Ngomhla zi-3 ku-Agasti, abacwaningi basebenzisa izakhiwo ze-photoconductive zikasilika wesicabucabu ukuthuthukisa inzwa ekwazi ukubona futhi ilinganise izinguquko ezincane kunkomba ye-refractive yezixazululo zebhayoloji, okuhlanganisa i-glucose nezinye izinhlobo zezixazululo zikashukela.Inzwa entsha esekelwe ekukhanyeni ingase isetshenziselwe ukukala ushukela wegazi nezinye izihlaziyi ze-biochemical.
Inzwa entsha ingathola futhi ilinganise ukugcwala kukashukela ngokusekelwe kunkomba ye-refractive.Inzwa yenziwe ngosilika ovela ku-giant wood spider Nephila pilipes, embozwe kunhlaka ye-biocompatible photocurable bese isebenza nge-nanolayer yegolide ehambisanayo.
"Izinzwa ze-glucose zibalulekile ezigulini ezinesifo sikashukela, kodwa le mishini ivame ukuhlasela, ingakhululekile futhi ayibizi," kusho umholi weqembu labacwaningi uChengyang Liu waseNational University eTaiwan."Usilika wesicabucabu waziwa ngezici zawo ezinhle kakhulu ze-optomechanical. Besifuna ukuhlola ukutholwa kwe-optical ngesikhathi sangempela kokugxilwa kukashukela okuhlukahlukene sisebenzisa le nto ehambisana ne-biocompatible."Ingasetshenziselwa ukunquma ukugcwala kwe-fructose, i-sucrose, ne-glucose okusekelwe ekushintsheni kwenkomba ye-refractive yesisombululo.Usilika wesicabucabu ulungele ukusetshenziswa okukhethekile ngoba awudluliseli nje ukukhanya njengefiber optical, kodwa futhi unamandla kakhulu futhi unwebeka.
Ukuze benze inzwa, abacwaningi bavune usilika wesicabucabu se-dragline spider giant wood spider Nephila pilipes.Basonga usilika ongama-microns angu-10 nje ububanzi nge-biocompatible light-curable resin, futhi bawelapha ukuze kwakheke indawo ebushelelezi, evikelayo.Lokhu kwakha uhlaka lwefiber optical ububanzi obucishe bube yi-100 microns, nosilika wesicabucabu njengomongo kanye ne-resin njenge-cladding.Bese, bengeza ama-nanolay egolide asebenzisanayo ukuze kuthuthukiswe amandla okuzwa kwe-fiber.
Le nqubo yakha isakhiwo esifana nocingo esineziphetho ezimbili.Ukwenza izilinganiso, isebenzisa i-fiber optical.Abacwaningi bacwilisa isiphetho esisodwa kwisampula ewuketshezi futhi baxhuma enye ekugcineni kumthombo wokukhanya kanye ne-spectrometer.Lokhu kwavumela abacwaningi ukuba bathole inkomba ye-refractive futhi bayisebenzise ukuze banqume uhlobo lukashukela kanye nokugxila kwawo.
