I-Ag nanopowder ingafakwai-antibacterial:

Umphumela we-antibacterial wesiliva ungalandelelwa emuva kumaGreki namaRoma, awandisa isikhathi sokuphuza kwawo ngokugcina amanzi ezitsheni zesiliva.Ama-ion esiliva akhululwa odongeni lwesitsha, futhi ama-ion esiliva asebenzisana nama-enzyme abalulekile webhaktheriya kanye namaqembu e-protein sulfhydryl ukuze kuzuzwe imiphumela ye-antibacterial.Lokhu kuthinta ukuphefumula kwamangqamuzana nokuthuthwa kwe-ion kulo lonke ulwelwesi, futhi lesi sifo siholela ekufeni kwamangqamuzana.Ezinye izindlela zokulwa namagciwane ebusheni be-nanoparticles esiliva nazo ziye zahlongozwa.Ama-nanoparticles esiliva angabamba bese angena odongeni lweseli yebhaktheriya, abangele ukulimala kwesakhiwo kulwelwesi lweseli.Ukukhiqizwa kwezinhlobo ze-oxygen esebenzayo ebusweni be-nanoparticles esiliva kungabangela ukucindezeleka kwe-oxidative futhi kunikeze enye indlela yokulimala kwamangqamuzana.Ubuthi obukhethekile kubhaktheriya ngenkathi kugcinwa ubuthi obuphansi kubantu buye benza ama-nanoparticles esiliva ahlanganiswe emikhiqizweni ehlukahlukene, okuhlanganisa ukugqokwa kwamanxeba, izinto zokupakisha kanye nezingubo zokulwa ne-surface antifouling.

Omaka be-Bioimaging nokuhlosiwe
Ama-nanoparticles esiliva asebenza kahle ngendlela emangalisayo ekumunceni nasekuhlakazeni ukukhanya, futhi angasetshenziselwa ukulebula nokuthwebula izithombe.Isigaba sesiphambano esihlakazeka kakhulu se-nanoparticles singavumela ama-nanoparticles esiliva angawodwa ukuthi afakwe isithombe ngaphansi kwesibonakhulu sensimu emnyama noma isistimu ye-imaging ye-hyperspectral.Ngokuhlanganisa ama-biomolecules (njengamasosha omzimba noma ama-peptide) endaweni yawo, ama-nanoparticles esiliva angaqondiswa kumaseli athile noma izingxenye zeseli.Ukunamathiselwa kwe-molecule eqondiswe phezulu kungafezwa ngokukhangiswa ebusweni be-nanoparticle, noma ngokuhlangana okuhlangene noma ukukhangiswa ngokomzimba.
