Among biocontrol fungi, Trichoderma species produce a wide range of bioactive compounds with antifungal activities. In this study, Di-(2-Ethylhexyl) Phthalate (DEHP) is identified via gas chromatog.-mass spectrometry (GC-MS) device in Trichoderma atroviridae (1-3) secondary metabolites and its antifungal effectiveness is confirmed. An eco-friendly approach for the extraction of DEHP is carried out by a nanoporous molecularly imprinted methacrylic acid-based network copolymer as a solid sorbent. Molecularly imprinted polymers (MIPs) are synthesized by pprotein polymn using DEHP as a template, methacrylic acid (MAA) as a functional monomer, and trimethylolpropane trimethacrylate (TRIM) as a cross-linker with mol. ratio (1: 4: 8). After the removal of DEHP, the nanoporous polymer could recognize and rebind specifically the same or structurally very similar mols. The synthesized MIPs exhibit a suitable tendency to absorb the template with the highest binding capacity of 300 mg/g for DEHP in n-Hexane solvent as a solid phase extraction (SPE) system. The measured particle size of the MIPs with dynamic light scattering (DLS) is reported at 75.38 nm. In addition, the porosity of the MIPs is evaluated by nitrogen gas adsorption/desorption using Brouneur Emmet Teller (BET) anal. Indicate that nanoporous MIPs with an av pore diameter of 2.70 nm and a sp surface area of 309 (cm3/g) is achieved. According to the above-mentioned results, nanoporous MIPs could be considered as an acceptable candidate for the seperation of antifungal bioactive compounds (natural fungicide) such as DEHP as an eco-friendly method in order to replace chem. pesticides.

M.; Sampaio, Paula; Sales, Maria Goreti Ferreira published the artcile< Cellulose-based hydrogel on quantum dots with molecularly imprinted polymers for the detection of CA19-9 protein cancer biomarker>, Computed Properties of 3290-92-4, the main research area is cancer biomarker CA19 9 cellulose hydrogel mol imprinted polymer; CA 19–9 protein; Imprinted cellulose hydrogels; Molecularly imprinted polymers; Optical sensor; Pancreatic cancer diagnosis; Quantum dots.

Molecularly imprinted polymers MIPs were successfully assembled around quantum dots (QDs), for the detection of the protein biomarker CA19-9 associated to pancreatic cancer (PC). These imprinted materials MIP@QDs were incorporated within the cellulose hydrogel with retention of its conformational structure inside the binding cavities. The concept is to use MIPs which function as the biorecognition elements, conjugated to cadmium telluride QDs as the sensing system. The excitation wavelength was set to 477 nm and the fluorescence signal was measured at its maximum intensity, with an emission range between 530 and 780 nm. The fluorescence quenching of the imprinted cellulose hydrogels occurred with increasing concentrations of CA19-9, showing linearity in the range 2.76 x 10 -2 – 5.23 x 10 2 U/mL, in a 1000-fold diluted human serum. Replicates of the imprinted hydrogel show a linear response below the cut-off values for pancreatic cancer diagnosis (< 23 U/mL), a limit of detection of 1.58 x 10 -3 U/mL and an imprinting factor (IF) of 1.76. In addition to the fact that the imprinted cellulose hydrogel displays good stability and selectivity towards CA19-9 when compared with the non-imprinted controls, the conjugation of MIPs to QDs increases the sensitivity of the system for an optical detection method towards ranges within clin. significance. This fact shows potential for the imprinted hydrogel to be applied as a sensitive, low-cost format for point-of-care tests (PoCTs).

Photoswitchable fluorescent nanomaterials have received much attention due to their versatile applications but they normally do not show high-contrast red fluorescence. Herein, we report novel photoswitchable red fluorescent polymer nanoparticles (PRFPNs) based on fluorescence resonance energy transfer (FRET) from Nile Red (fluorescent donor) to spirothiopyran (photochromic acceptor). Both the donor and the acceptor are covalently incorporated into nanoparticles through a facile miniemulsion polymerization The obtained PRFPNs exhibit not only reversible photoswitching of fluorescence characteristics under alternate UV and visible light irradiation, but also tunable FRET efficiency, favorable photoreversibility, excellent fluorescence stability, ultrahigh brightness and high contrast on/off fluorescence. We demonstrate that these PRFPNs can be used in rewritable information encryption, anti-counterfeiting and reversible fluorescence bioimaging in living cells.

In this study, a light cross-linkable biocomposite scaffold based on a photo-cross-linkable poly (propylene fumarate) (PPF)-co-polycaprolactone (PCL) tri-block copolymer was synthesized and characterized. The developed biodegradable scaffold was further modified with β-tricalcium phosphate (β-TCP) bioceramic for bone tissue engineering applications. The developed biocomposite was characterized using H NMR and Fourier transform IR spectroscopy. Moreover, the bioceramic particle size distribution and morphol. were evaluated using Brunauer-Emmett-Teller method, X-ray diffraction, and SEM. The mech. properties and biodegradation of the scaffolds were also evaluated. Cytotoxicity and mineralization assays were performed to analyze the biocompatibility and bioactivity capacity of the developed biocomposite. The characterization data confirmed the development of a biodegradable and photo-cross-linkable PCL-based biocomposite reinforced with β-TCP bioceramic. In vitro analyses demonstrated the biocompatibility and mineralization potential of the synthesized bioceramic. Altogether, the results of the present study suggest that the photo-cross-linkable PCL-PPF-PCL tri-block copolymer reinforced with β-TCP is a promising biocomposite for bone tissue engineering applications. According to the results, this newly synthesized material has a proper chem. composition for further clin.-relevant studies in tissue engineering.

Ceglowski, Michal; Kurczewska, Joanna; Ruszkowski, Piotr; Liberska, Joanna; Schroeder, Grzegorz published the artcile< The influence of crosslinking agent onto adsorption properties, release behavior and cytotoxicity of doxorubicin-imprinted microparticles>, Formula: C18H26O6, the main research area is doxorubicin molecularly imprinted polymer microparticle crosslinking agent adsorption release; Cell culture; Doxorubicin; Drug delivery; Microspheres; Molecularly imprinted polymers.

Molecularly imprinted polymers (MIPs) are synthetic polymers that possess cavities selective towards their mol. templates and have found many applications in separation science, drug delivery, and catalysis. Here, we report the synthesis of doxorubicin-imprinted microparticles crosslinked with two different compounds (ethylene glycol dimethacrylate or trimethylolpropane trimethacrylate) and examination of their physicochem. properties. During the synthesis methacrylic acid was used as functional monomer and 2-hydroxyethyl methacrylate was added into polymerization mixture to increase hydrophilicity of the obtained materials and therefore improve interactions with aqueous release medium. The influence of initial concentration and contact time onto doxorubicin adsorption by obtained MIPs microparticles have been investigated. The microparticles obtained using ethylene glycol dimethacrylate as a crosslinker showed 3 times higher adsorption properties towards doxorubicin, than the ones obtained using trimethylolpropane trimethacrylate crosslinker. The release kinetics of doxorubicin from drug-loaded MIPs microparticles has been proven to be dependent upon crosslinker used and pH of the release medium. For drug-loaded MIPs microparticles obtained using both crosslinkers the IC50 values measured for cancer cell were comparable to the ones measured for pure doxorubicin, whereas the cytotoxicity towards normal HDF cell lines was lower.

A. published the artcile< Effect of gamma dose rate in the crosslinking of PVC composites used for radiation protection in radiology>, HPLC of Formula: 3290-92-4, the main research area is PVC tantalum carbide composite crosslinking gamma irradiation radiation protection.

Flexible PVC composites loaded with various levels of tantalum carbide (TaC) were gamma irradiated at two different dose rates and their effect on crosslinking level, thermal stability and mech. properties evaluated. The shielding properties of composites against X-Rays at radiodiagnosis energies were also evaluated. Gel percentage results indicate a relatively stable crosslinking level after irradiation, only some reduction was observed for highly loaded composite treated at a low dose rate, although thermal stability observed by TGA was maintained. TaC particles were properly dispersed within the PVC material, as seen by SEM and toughness increased when both E’ and E” Moduli were enhanced after irradiation; even Tg, followed by Tanδ DMA curves, increased noticeably after treatment and for the higher TaC loaded composites, particularly when treated at low dose rate irradiation D. measurements indicated lighter and manageable materials with respect to traditional shielding items. The shielding properties for composites, evaluated in a clin. X-Ray apparatus, in the 50-129 kV interval, show mass attenuation coefficients close to the ones reported for lead, even higher for 50% TaC loaded composite and a very competitive half-value layer (HVL) for all of them.

Okesanjo, Omotola; Tennenbaum, Michael; Fernandez-Nieves, Alberto; Meredith, J. Carson; Behrens, Sven H. published the artcile< Rheology of capillary foams>, Category: esters-buliding-blocks, the main research area is vinyl chloride copolymer capillary foam rheol.

Aqueous foams are ubiquitous; they appear in products and processes that span the cosmetics, food, and energy industries. The versatile applicability of foams comes as a result of their intrinsic viscous and elastic properties; for example, foams are exploited as drilling fluids in enhanced oil recovery for their high viscosity. Recently, so-called capillary foams were discovered: a class of foams that have excellent stability under static conditions and whose flow properties have so far remained unexplored. The unique architecture of these foams, containing oil-coated bubbles and a gelled network of oil-bridged particles, is expected to affect foam rheol. In this work, we report the first set of rheol. data on capillary foams. We study the viscoelastic properties of capillary foams by conducting oscillatory and steady shear tests. We compare our results on the rheol. properties of capillary foams to those reported for other aqueous foams. We find that capillary foams, which have low gas volume fractions, exhibit long lasting rheol. stability as well as a yielding behavior that is reminiscent of surfactant foams with high gas volume fractions.

A restricted access molecularly imprinted polymer (RAMIP) crosslinked with bovine serum albumin (BSA) was prepared on the surface of the mesoporous UiO-66-NH2 metal-organic framework (MOF). The surface morphol., imprinting behavior, and protein exclusion properties of UiO-66-NH2@RAMIP@BSA were investigated. The maximum adsorption capacity was 50.55 mg g-1 for ofloxacin, with a 99.4% protein exclusion rate. Adsorption equilibrium was reached in 9 min. Combined with RP-HPLC, a solid-phase extraction column filled with UiO-66-NH2@RAMIP@BSA was used to selectively enrich and analyze ofloxacin and enrofloxacin antibiotics from bovine serum with recoveries of 93.7-104.2% with relative standard deviations of 2.0-4.5% (n = 3). The linear range and the limit of detection were 0.1-100μg mL-1 and 15.6 ng mL-1, resp. These results suggest that UiO-66-NH2@RAMIP@BSA is an efficient pretreatment adsorbent for biol. sample anal.
