Synthesis ntawm kub nanoparticles ntawm qhov chaw tau ua tiav los ntawm incubation ntawm poly (dimethylsiloxane) (PDMS) films nyob rau hauv tetrachloroauric (III) acid thiab chitosan tov nyob rau hauv chav tsev kub thiab 4 degrees C. Ib qho tseem ceeb point nyob rau hauv txoj kev tshawb no yog hais tias cov synthesis xaiv. tshwm sim ntawm PDMS nto.Cov kev soj ntsuam no muaj qhov sib txawv ntawm cov tshuaj tiv thaiv hauv kev daws teeb meem, uas tsis muaj cov khoom tuaj yeem tsim nyob rau hauv chav tsev kub.Kev suav ntawm qhov chaw plasmon bands (SPBs) raws li Mie txoj kev xav qhia tias cov khoom yog ib feem coated los ntawm chitosan molecules, thiab cov txiaj ntsig kev sim tau lees paub qhov kev suav theoretical.Lub tswv yim txheej txheem yog tias chitosan molecules adsorbed los yog luam tawm ntawm PDMS nto ua raws li kev txo qis / stabilizing cov neeg ua haujlwm.Tsis tas li ntawd, PDMS cov yeeb yaj kiab ua qauv nrog chitosan tuaj yeem ua rau muaj kev sib txuas hauv zos ntawm cov nanoparticles kub hauv cov cheeb tsam capped nrog chitosan nkaus xwb.Nyob rau hauv txoj kev no, cov qauv colloidal tau fabricated rau ntawm qhov chaw nrog siab spa tial selectivity ib txhij nrog cov synthesis ntawm cov khoom.Nto-induced fluorescence quenching tau pom nyob rau hauv cov cheeb tsam capped nrog kub nanoparticles thiab.
