Nanofibrous silica nke dabeere n'usoro guzoro maka electrospun ultra-thin Layer chromatography (E-UTLC) ka akọwara.A na-emepụta nanofibers site na electrospinning ngwọta nke silica nanoparticles gbasasịrị na ngwọta polyvinylpyrrolidone iji mepụta silica/polymer nanofibers mejupụtara.A na-emepụta usoro nkwụsị site na nanofibers as-spun, ma ọ bụ nanofibers na-ekpo ọkụ ma ọ bụ iji gafee polyvinylpyrrolidone ma ọ bụ iji calcine wee wepụ polymer.A tụlere nanofibers as-spun, crosslinked, na calcined nanofibers nwere ọkpụrụkpụ ute yiri ya (23-25 ​​μm) dị ka usoro kwụ ọtọ maka nkewa E-UTLC nke akwa akwa laser na amino acid ma jiri ya tụnyere efere silica TLC azụmahịa.Efere nanofiber dị ka-spun na-enye ngwa ngwa ngwa mkpanaka ngwa ngwa, mana dị ka nanofibers ndị ọzọ dabere na polymer, nkewa dabara naanị na usoro iji ihe na-adịghị edozi nke polymer.Nanofibers nwere njikọ chiri anya abụghị oke n'ihe gbasara nkwụsi ike kemịkalụ, mana nkewa na-emepụta ụdị ntụpọ ọdụdụ.Ọnweghị oke nhịahụ n'usoro usoro mkpanaaka, ihe mgbaze nyocha, na usoro nhụhụ anya ka ahụrụ maka nanofibers calcined.A na-eme nkewa nke amino acid dị oke mma na 15 mm na efere nanofiber calcined, nke nwere ọkwa dị elu dị ka 8.6 μm, yana ọnụ ọgụgụ efere dị ka 1400.
