Мазкур мақолада алмашиниш даражаси (АД) 0,65-0,85 ва полимерланиш даражаси (ПД) 200-600 бўлган натрий-карбоксиметилцеллюлоза (Na-КМЦ) эритмасида барқарор кумуш нанозарралари (АgНЗ) фотокимёвий қайтарилиш усулида синтез қилинган. Таркибида АgНЗ ва Na-КМЦ тутган плёнкаларнинг физик-кимёвий, физик-механик ва куйган яраларни даволовчи хоссалари ҳамда бактерицид фаоллиги ўрганилган. Na-КМЦ плёнкаларида шаклланган АgНЗнинг ўлчами, шакли ва миқдори атом кучланишли микроскопия (АКМ), УБ-спектроскопия, динамик ёруғлик тарқалиши (DLS) ва трансмиссион электрон микроскопия (TЭМ) усуллари орқали аниқланган. Na-КМЦ ва у асосида олинган имплант-плёнкаларда кумуш нитрат тузи концентрацияси ортиши билан фотокимёвий қайтариш натижасида шаклланаётган АgНЗ ўлчам ва шаклларининг ўзгариши аниқланди. Ўлчамлари 5–35 нм бўлган АgНЗ тутган Na-КМЦ плёнкалар юқори бактерицид фаоллик намоён қилганлиги ва 14 кун давомида куйган яраларни даволаш хусусиятига эга эканлиги аниқланди.
