Musi wa3 Nyamavhuvhu, vaongorori vakashandisa iyo photoconductive zvimiro zvespider silk kugadzira sensor inogona kuona uye kuyera diki shanduko mune refractive index yebiological solution, kusanganisira glucose nemamwe marudzi eshuga mhinduro.Iyo nyowani-yakavakirwa sensor sensor inogona kushandiswa kuyera shuga yeropa uye mamwe biochemical analytes.
Iyo sensor nyowani inogona kuona uye kuyera shuga yekumisikidza zvichibva pane refractive index.Iyo sensor inogadzirwa nesirika kubva kune hofori yehuni spider Nephila pilipes, iyo yakavharidzirwa mune biocompatible photocurable resin uye yobva yashanda neine biocompatible goridhe nanolayer.
"Glucose sensors yakakosha kuvarwere vane chirwere cheshuga, asi michina iyi inowanzova isina kunaka, kusagadzikana uye haina mari," akadaro mutungamiri weboka rekutsvagisa Chengyang Liu anobva kuNational University kuTaiwan."Spider silk inozivikanwa nekunaka kwayo optomechanical properties. Taida kuongorora chaiyo-nguva yekuona maziso emhando dzakasiyana dzeshuga tichishandisa iyi biocompatible material."Inogona kushandiswa kuona kuwanda kwefructose, sucrose, uye glucose izvo zvinoenderana nekuchinja mune refractive index yemhinduro.Spider silk ndiyo yakanakira kushandiswa kwakakosha nekuti haingofambisi mwenje seoptical fiber, asiwo yakasimba uye elastic.
Kugadzira sensor, vaongorori vakakohwa sirika yedandemutande kubva muhombe yehuni spider Nephila pilipes.Vakaputira sirika inongori 10 microns muhupamhi ine biocompatible light-curable resin, uye vakairapa kuti iite nzvimbo yakatsetseka, inodzivirira.Izvi zvakagadzira optical fiber chimiro icho dhayamita ingangoita 100 microns, ine spider sirika sepakati uye resin seyakavharika.Ipapo, ivo vakawedzera biocompatible goridhe nanolayers kuwedzera iyo fiber yekunzwa kugona.
Iyi nzira inoumba chimiro chakafanana newaya chine magumo maviri.Kugadzira zviyero, inoshandisa optical fiber.Vatsvakurudzi vakanyudza mugumo mumwe mumuenzaniso wemvura uye vakabatanidza imwe mugumo kune chiedza chechiedza uye spectrometer.Izvi zvakabvumira vatsvakurudzi kuti vaone refractive index uye vakaishandisa kuti vaone rudzi rweshuga uye kuiswa kwayo.
