Nanofibrous silica-based stationary phases for electrospun Ultra-thin layer chromatography (E-UTLC) akufotokozedwa.Nanofibers opangidwa ndi electrospinning njira ya silika nanoparticles omwazikana mu polyvinylpyrrolidone njira kulenga gulu silika/polima nanofibers.Magawo osasunthika adapangidwa kuchokera ku as-spun nanofibers, kapena nanofibers adatenthedwa mwina kuti adutse polyvinylpyrrolidone kapena calcine ndikuchotsa polima.As-spun, crosslinked, and calcined nanofibers okhala ndi makulidwe ofanana (23-25 ​​μm) adawunikidwa ngati magawo osakhazikika a E-UTLC kupatukana kwa utoto wa laser ndi ma amino acid ndikuyerekeza ndi mbale zamalonda za silika TLC.Ma mbale a as-spun nanofiber amapereka ma liwiro othamanga, koma monga ma nanofiber ena opangidwa ndi polima, kulekanitsa kunali kogwirizana ndi njira zogwiritsa ntchito ma nosolvents a polima.Ma nanofiber ophatikizika analibe malire malinga ndi kukhazikika kwamankhwala, koma kupatukana kunapanga mawonekedwe a mawanga.Palibe malire okhudzana ndi magawo am'manja, zosungunulira za analyte, ndi njira zowonera zomwe zidawonedwa pama nanofibers owerengeka.Kulekanitsa kothandiza kwambiri kwa ma amino acid kunachitika mu 15 mm pa mbale za calcined nanofiber, zokhala ndi kutalika kwa mbale zotsika mpaka 8.6 μm, ndi manambala a mbale zazikulu ngati 1400. Kuwongolera kowonjezera kwa nanofibers kunapereka nthawi zazifupi zowunikira komanso m'lifupi mwake.Kukulitsidwa kwa magawo oyima ku ma nanofibers opangidwa ndi silika kumakulitsa kwambiri magawo am'manja, ma analyte solvents, ndi njira zowonera zomwe zingagwiritsidwe ntchito kupatukana kwa E-UTLC.
