Kim, Sehyun published the artcileIn Vitro and In Vivo Human Body Odor Analysis Method Using GO:PANI/ZNRs/ZIF-8 Adsorbent Followed by GC/MS, SDS of cas: 6259-76-3, the main research area is graphene oxide polyaniline zinc nanorod ZIF 8 body odor; GO:PANI/ZNRs/ZIF−8; headspace-in needle microextraction; human body odor; needle-based adsorbent; response surface methodology; volatile organic compounds.
Among various volatile organic compounds (VOCs) emitted from human skin, trans-2-nonenal, benzothiazole, hexyl salicylate, α-hexyl cinnamaldehyde, and iso-Pr palmitate are key indicators associated with the degrees of aging. In our study, extraction and determination methods of human body odor are newly developed using headspace-in needle microextraction (HS-INME). The adsorbent was synthesized with graphene oxide:polyaniline/zinc nanorods/zeolitic imidazolate framework-8 (GO:PANI/ZNRs/ZIF-8). Then, a wire coated with the adsorbent was placed into the adsorption kit to be directly exposed to human skin as in vivo sampling and inserted into the needle so that it was able to be desorbed at the GC injector. The adsorption kit was made inhouse with a 3D printer. For the in vitro method, the wire coated with the adsorbent was inserted into the needle and exposed to the headspace of the vial. When a cotton T-shirt containing body odor was transferred to a vial, the headspace of the vial was saturated with body odor VOCs. After volatile organic compounds were adsorbed in the dynamic mode, the needle was transferred to the injector for anal. of the volatile organic compounds by gas chromatog./mass spectrometry (GC/MS). The conditions of adsorbent fabrication and extraction for body odor compounds were optimized by response surface methodol. (RSM). In conclusion, it was able to synthesize GO:PANI/ZNRs/ZIF-8 at the optimal condition and applicable to both in vivo and in vitro methods for body odor VOCs anal.
