Ngomhla we-3 ka-Agasti, abaphandi basebenzise iipropati ze-photoconductive zesilika yesigcawu ukuphuhlisa inzwa ekwazi ukubona kunye nokulinganisa utshintsho oluncinci kwi-index refractive yezisombululo zebhayoloji, kuquka i-glucose kunye nezinye iintlobo zezisombululo zeswekile.Inzwa entsha esekwe ekukhanyeni ingasetyenziselwa ukulinganisa iswekile yegazi kunye nolunye uhlalutyi lwe-biochemical.

Inzwa entsha inokubona kwaye ilinganise i-sugar concentration esekelwe kwi-index refractive index.Isivamvo senziwe ngesilika evela kwisigcawu somthi omkhulu iNephila pilipes, egqunywe kwintlaka ekwazi ukufotokopa ekwaziyo ukufotokopa kwaye isebenze ngenanolayer yegolide ehambelana nendalo.

Inkokeli yeqela lophando uChengyang Liu, inkokeli yeqela lophando, uChengyang Liu, wathi: "Ii-sensors ze-glucose zibalulekile kwizigulana ezinesifo seswekile, kodwa ezi zixhobo zihlala zihlasela, zingonwabanga kwaye azibizi mali ininzi.""I-silk yesigcawu iyaziwa ngeempawu zayo ezibalaseleyo ze-optomechanical. Besifuna ukuphonononga ukubonwa kwe-optical real-time yeentlobo ezahlukeneyo zeswekile kusetyenziswa le nto i-biocompatible."Ingasetyenziselwa ukumisela i-concentration ye-fructose, i-sucrose, kunye ne-glucose esekelwe kwiinguqu kwi-index refractive yesisombululo.Isilika yesigcawu yeyona nto ifanelekileyo kwisicelo esikhethekileyo kuba ayigqithisi nje ukukhanya njengefiber optical, kodwa yomelele kakhulu kwaye iyalastiki.

Ukwenza inzwa, abaphandi bavuna isilika yesigcawu se-dragline spider giant wood spider Nephila pilipes.Basonga isilika ene-10 microns nje ububanzi kunye ne-biocompatible light-curable resin, kwaye bayinyanga ukuze yenze umphezulu ogudileyo, okhuselayo.Oku kudale ulwakhiwo lwefiber optical enedayamitha emalunga ne-100 microns, kunye nesilika yesigcawu njengombindi kunye neresin njengolugqubuthelo.Emva koko, bongeze iinanolay zegolide ezihambelana ne-biocompatible ukuphucula amandla okuva kwefiber.

Le nkqubo yenza isakhiwo esifana nocingo kunye neziphelo ezimbini.Ukwenza imilinganiselo, isebenzisa i-fiber optical.Abaphandi bantywila isiphelo esinye kwisampulu yolwelo kwaye badibanisa enye isiphelo kumthombo wokukhanya kunye ne-spectrometer.Oku kwavumela abaphandi ukuba babone i-index refractive index kwaye bayisebenzise ukumisela uhlobo lweswekile kunye nokugxilwa kwayo.
