Ushbu maqolada kumush nanozarrachalarini o‘simlik ekstraktlari, mikroorganizmlar va biopolimerlar yordamida “yashil” usulda hosil qilishning kolloid-kimyoviy negizlari tahlil qilingan. Yadrolanish (nukleatsiya) va zarracha o‘sishi jarayonlarining klassik nazariyasi, kolloid tizimlarning to‘planishga qarshi turg‘unligini belgilaydigan elektr zaryadi va jismoniy to‘siqqa asoslangan itarilish omillari, fitokimyoviy birikmalarning ikkilamchi — ham qaytaruvchi, ham qoplovchi (barqarorlashtiruvchi) — vazifasi, shuningdek, yuzaviy plazmon rezonansining nazorat-aniqlash ahamiyati yoritilgan. Hosil qilish jarayonining ko‘rsatkichlari (pH, harorat, ekstrakt miqdori, reaksiya davomiyligi) zarracha o‘lchami va o‘lcham bir xilligi darajasiga ta’siri tizimlashtirilgan holda ko‘rib chiqilgan.Keywords
