Uyu munsi turashaka gusangira antibacterial zimwe zikoresha ibikoresho bya nanoparticles nkibi bikurikira:

1. Nano silver

Ihame rya antibacterial ya nano silver material

(1).Hindura uburyo bwimikorere ya selile.Kuvura bagiteri hamwe nifeza ya nano birashobora guhindura uburyo bwimikorere ya selile, bigatera gutakaza intungamubiri nyinshi na metabolite, hanyuma amaherezo agapfa;

(2).Iion ya silver yangiza ADN

(3).Mugabanye ibikorwa bya dehydrogenase.

(4).Guhangayikishwa na Oxidative.Ifeza ya Nano irashobora gutuma ingirabuzimafatizo zibyara ROS, bikagabanya kandi ibikubiye muri coenzyme ya II (NADPH) oxydease inhibitor (DPI), biganisha ku rupfu.

Ibicuruzwa bifitanye isano: Ifu ya Nano ifu, amabara ya feza ya antibacterial, amavuta ya antibacterial ya feza

2.Nano zinc 

Hariho uburyo bubiri bwa antibacterial ya nano-zinc oxyde ZNO:

(1).Uburyo bwa antibacterial Photocatalytic.Ni ukuvuga, okiside ya nano-zinc irashobora kubora electroni zishizwemo nabi mumazi no mwuka munsi yumucyo wizuba ryizuba, cyane cyane urumuri ultraviolet, mugihe usize umwobo ushizwemo neza, ushobora gutuma umwuka wa ogisijeni uhinduka mukirere.Ni ogisijeni ikora, kandi igahindura hamwe na mikorobe itandukanye, bityo ikica bagiteri.

(2).Uburyo bwa antibacterial uburyo bwo gusesa ibyuma ion ni uko zinc ion zizagenda zisohoka buhoro buhoro.Iyo ihuye na bagiteri, izahuza na protease ikora muri bagiteri kugirango idakora, bityo yice bagiteri.

3. Nano titanium

Dioxyde ya Nano-titanium ibora bagiteri ikoresheje fotokatisiti kugirango igere kuri antibacterial.Kubera ko imiterere ya elegitoronike ya dioxyde ya nano-titanium irangwa na bande ya TiO2 yuzuye hamwe na bande itwara ubusa, muri sisitemu y’amazi n’umwuka, dioxyde ya nano-titanium ihura n’izuba, cyane cyane imirasire ya ultraviolet, iyo ingufu za electron zigeze cyangwa irenze icyuho cyayo.Urashobora umwanya.Electron irashobora gushimishwa kuva kumurongo wa valence kugeza kumurongo wogutwara, kandi imyobo ijyanye nayo ikorwa mumurongo wa valence, ni ukuvuga electron hamwe nu mwobo byombi.Munsi yumurimo wumuriro wamashanyarazi, electron nu mwobo biratandukanye kandi bimukira mumyanya itandukanye hejuru yubutaka.Urukurikirane rw'ibisubizo bibaho.Umwuka wa ogisijeni wafatiwe hejuru ya TiO2 adsorbs hanyuma ugatega electroni kugirango ube O2, kandi radicals ya superoxide yakozwe na reaction (okiside) hamwe nibintu byinshi kama.Mugihe kimwe, irashobora kwitwara nibintu kama muri bagiteri kubyara CO2 na H2O;mugihe ibyobo bihindura okiside ya OH na H2O byamamajwe hejuru ya TiO2 kugeza · OH, · OH ifite imbaraga zikomeye za okiside, yibasira imiyoboro idahagije yibintu kama cyangwa gukuramo H Atome ibyara radicals yubusa, bigatera urunigi, hanyuma amaherezo bigatera bagiteri kubora.

4. Umuringa wa Nano,nano umuringa, nano cuprous oxyde

Umuringa wuzuye wa nanoparticles hamwe na bagiteri zashizwemo nabi bituma nanoparticles y'umuringa ihura na bagiteri binyuze mu gukurura umuriro, hanyuma nanoparticles y'umuringa ikinjira mu ngirabuzimafatizo za bagiteri, bigatuma urukuta rwa bagiteri rumeneka kandi amazi ya selile akagenda. hanze.Urupfu rwa bagiteri;ibice bya nano-umuringa byinjira mu ngirabuzimafatizo icyarimwe birashobora gukorana na enzymes za poroteyine ziri mu ngirabuzimafatizo za bagiteri, ku buryo iyo misemburo itangwa kandi idakora, bityo ikica bagiteri.

Byombi byibanze byumuringa numuringa bifite antibacterial, mubyukuri, byose ni ion zumuringa muguhindura.

Ingano ntoya, ningaruka nziza ya antibacterial mubijyanye nibikoresho bya antibacterial, ningaruka ntoya.

5.Graphene

Igikorwa cya antibacterial yibikoresho bya graphene gikubiyemo uburyo bune:

(1).Gutobora kumubiri cyangwa "icyuma cya nano" uburyo bwo guca;

(2).Indwara ya bagiteri / membrane iterwa no guhagarika umutima;

(3).Transmembrane itwara abantu hamwe na / cyangwa gukura kwa bagiteri guterwa no gutwikira;

(4).Akagari ka selile ntigahinduka mugushyiramo no gusenya ibintu bigize selile.

Ukurikije uburyo butandukanye bwo guhuza ibikoresho bya graphene na bagiteri, uburyo bwinshi twavuze haruguru bukomatanya butera gusenya burundu uturemangingo (ingaruka za bagiteri) kandi bikabuza gukura kwa bagiteri (ingaruka za bagiteri).
