Nanofibrous silica-ku salaysan wejiyada taagan ee electrospun chromatography lakabka khafiifka ah (E-UTLC) ayaa lagu sifeeyay.Nanofibers waxaa lagu soo saaray elektrospinning xal silica nanoparticles ku kala firdhiyey xalalka polyvinylpyrrolidone si loo abuuro nanofibers silica/polymer isku dhafan.Wajiyada joogtada ah ayaa laga sameeyay nanofibers as-spun, ama nanofiber-yada ayaa la kululeeyay si ay uga gudbaan polyvinylpyrrolidone ama in la calcine oo si door ah looga saaro polymerka.As-spun, crosslinked, and calcined nanofibers oo leh dhumucdiisuna waxay la mid tahay (23-25 ​​μm) ayaa lagu qiimeeyay inay yihiin wejiyada taagan ee kala-soocida E-UTLC ee midabada laysarka iyo amino acids iyo marka la barbar dhigo taarikada silica TLC ee ganacsiga.Taarikada nanofiber-ka-soo-baxa ayaa bixiya xawaaraha wareega wareega ee degdega ah, laakiin sida nanofiber-yada kale ee polymer-ku-saleysan, kala-soocida waxay kaliya la jaan qaadayaan farsamooyinka isticmaalaya waxyaabaha aan milmaha lahayn ee polymerka.Nanofiber-yada isku-xiran ma ahayn kuwo xaddidan marka la eego xasilloonida kiimikada, laakiin kala-soociddu waxay soo saartay qaabab dabo leh.Ma jiraan wax xaddidan marka loo eego wejiyada guurguura, dareerayaasha falanqaynta, iyo farsamooyinka aragga ayaa lagu arkay nanofibers-ka la kariyey.Kala-soocida aadka waxtarka leh ee amino acids-ka ayaa lagu sameeyay 15 mm taarikada nanofiber ee calcined, oo leh dhererka saxanka ee la arkay sida ugu hooseeya 8.6 μm, iyo lambarrada saxanka sida weyn sida 1400. Isku-xidhka dheeraadka ah ee nanofibers-ka ayaa bixiyay waqtiyo falanqayn gaaban laakiin sidoo kale ballaadhka dhibcaha waaweyn.Kordhinta wejiyada taagan ee nanofibers-ku-salaysan silica waxay si weyn u balaadhisaa kala duwanaanshaha wejiyada wareega, dareerayaasha falanqaynta, iyo farsamooyinka aragga ee loo isticmaali karo kala-soocidda E-UTLC.
