Kuphatikizika kwa ma nanoparticles a golide pamtunda wakwaniritsidwa ndi kuyika kwa mafilimu a poly(dimethylsiloxane) (PDMS) mu tetrachloroauric (III) acid ndi chitosan solution pa kutentha kwa firiji ndi 4 ° C. Mfundo imodzi yofunika kwambiri mu phunziroli ndi yakuti kaphatikizidwe mwa kusankha. chinachitika pa PDMS pamwamba.Zowonerazi ndizosiyana kwambiri ndi zomwe zimachitika mu yankho, momwe palibe tinthu tating'onoting'ono tomwe timapanga kutentha.Kuwerengera kwa magulu a plasmon (SPBs) kutengera chiphunzitso cha Mie kumasonyeza kuti tinthu tating'onoting'ono tambirimbiri takutidwa ndi mamolekyu a chitosan, ndipo zotsatira zoyesera zimatsimikizira kuwerengera kwamalingaliro.Njira yomwe ikuyembekezeredwa ndi yakuti mamolekyu a chitosan omwe amatsatiridwa kapena kusindikizidwa pa PDMS amakhala ngati kuchepetsa / kukhazikika.Kuphatikiza apo, makanema a PDMS opangidwa ndi chitosan amatha kupangitsa kuti ma nanoparticles agolide apangidwe m'magawo okhala ndi chitosan okha.Mwanjira imeneyi, mapangidwe a colloidal anali opangidwa pamtunda wokhala ndi spa tial selectivity imodzi ndi kaphatikizidwe ka particles.Kuzimitsa kwa fluorescence kopangidwa ndi pamwamba kunkawoneka m'magawo okhala ndi ma nanoparticles agolide.
