Ukusetshenziswa kwe-Silver Nanoparticles

Okuningi kakhuluama-nanoparticles esilivaisebenzisa i-anti-bacterial and anti-virus yayo, izithasiselo ezihlukahlukene ephepheni, amapulasitiki, izindwangu ze-anti-bacterial anti-virus.Cishe i-0.1% ye-nano layered nano-silver inorganic antibacterial powder ine-inhibition eqinile futhi ibulala umphumela ku-escherichia coli, i-staphylococcus aureus nezinye inqwaba ye-pathogenic microorganism.Njengemikhiqizo emisha yokulwa nokutheleleka, inobubanzi obubanzi, akukho ukumelana nomuthi, ayithinteki ngenani le-PH kanye ne-antibacterial ehlala isikhathi eside, akulula ukuba i-oxided, nokunye.Ama-nanoparticles esiliva esetshenziswa ngempumelelo ekwakheni, ukuvikelwa kwezinsalela zamasiko, imikhiqizo yezokwelapha.

I-Silver nanoparticles antibacterial mechanism inezici ezimbalwa ezilandelayo:

1. izithako ezisebenzayo ze-antibacterial fibre effect ku-membrane yeseli amaprotheni.Ingakwazi ukubhubhisa ngokuqondile ulwelwesi lwama-bacterium cell, kubangele okuqukethwe kweseli ukuvuza.Ama-nanoparticles esiliva akhangiswe kulwelwesi lweseli ukuze avimbe amagciwane kanye nokunye ukukhula kwamagciwane, okungukuthi, isiliva le-nano lingamisa amabhaktheriya ukuze amunce izakhi ezibalulekile ezifana ne-amino acid, i-uracil, ngaleyo ndlela ivimbele ukukhula kwayo.

2. Ingaphezulu lendwangu elwa namagciwane likhipha ububanzi obuthile be-wavelength be-infrared ray, evimbela ukusebenza kwamagciwane, ibulale amagciwane.

3. umthelela we-surface catalytic we-nanoparticles esiliva, uthinta i-metabolism evamile yamagciwane kanye nokuzalana okuvamile ukubulala amagciwane.

Ukuhlakazwa kwama-nanoparticles esiliva ngokuvamile kunconywa ukuthi ukwengeza ama-surfactants kanye nendlela yokuhlakazeka komshini kuhlanganiswe, kuzofeza umphumela wokuhlakazeka okwengeziwe.Ungasebenzisa i-supersonic jet mill depolymerize kanye nokuguqulwa kwendawo yesiliva nanoparticles powder.Ukuguqulwa kwethu okuvame ukusetshenziswa kakhulu kuhlanganisa i-PVP, i-oleic acid, njll.
