Lero tikufuna kugawana zinthu zina za antibacterial za nanoparticles monga zili pansipa:

1. Nano siliva

Mfundo ya antibacterial ya nano silver material

(1).Kusintha permeability wa nembanemba selo.Kuchiza mabakiteriya ndi nano siliva kungasinthe permeability ya nembanemba ya selo, zomwe zimayambitsa kutaya kwa michere yambiri ndi metabolites, ndipo pamapeto pake maselo amafa;

(2).Silver ion imawononga DNA

(3).Chepetsani ntchito ya dehydrogenase.

(4).Kupanikizika kwa okosijeni.Siliva ya Nano imatha kupangitsa maselo kupanga ROS, zomwe zimachepetsanso zomwe zili mucoenzyme II (NADPH) oxidase inhibitors (DPI), zomwe zimapangitsa kuti cell kufa.

Zogwirizana: Nano siliva ufa, akuda siliva antibacterial madzi, mandala siliva antibacterial madzi

2.Nano zinc oxide 

Pali njira ziwiri za antibacterial za nano-zinc oxide ZNO:

(1).Photocatalytic antibacterial mechanism.Ndiko kuti, nano-zinc oxide imatha kuwola ma elekitironi oipitsidwa m'madzi ndi mpweya pansi pa kuwala kwa dzuwa, makamaka kuwala kwa ultraviolet, ndikusiya mabowo okhala ndi mpweya wabwino, zomwe zingayambitse kusintha kwa mpweya mumlengalenga.Imakhala ndi okosijeni yogwira, ndipo imadzaza ndi tizilombo tosiyanasiyana, potero imapha mabakiteriya.

(2).Njira ya antibacterial ya kusungunuka kwa ayoni yachitsulo ndikuti ayoni a zinc adzamasulidwa pang'onopang'ono.Zikakumana ndi mabakiteriya, zimaphatikizana ndi protease yogwira mu mabakiteriya kuti ikhale yosagwira ntchito, motero imapha mabakiteriya.

3. Nano titanium oxide

Nano-titaniyamu woipa amawola mabakiteriya pansi pa zochita za photocatalysis kukwaniritsa antibacterial kwenikweni.Popeza dongosolo lamagetsi la nano-titanium dioxide limadziwika ndi gulu lathunthu la TiO2 valence ndi gulu lopanda kanthu la conduction, mu dongosolo la madzi ndi mpweya, nano-titaniyamu woipa wamadzimadzi amawonekera ndi kuwala kwa dzuwa, makamaka kuwala kwa ultraviolet, pamene mphamvu ya electron ikufika kapena imadutsa kusiyana kwa gulu lake.Mutha nthawi.Ma electron amatha kukondwera kuchokera ku gulu la valence kupita ku gulu la conduction, ndipo mabowo ofanana amapangidwa mu gulu la valence, ndiko kuti, ma electron ndi ma hole awiriawiri amapangidwa.Pansi pa zochita za magetsi, ma electron ndi mabowo amasiyanitsidwa ndikupita kumalo osiyanasiyana pa tinthu tating'onoting'ono.Zotsatira zingapo zimachitika.Mpweya womwe umagwidwa pamwamba pa TiO2 adsorbs ndi misampha ma elekitironi kuti apange O2, ndipo opangidwa ndi superoxide anion radicals amachita (oxidize) ndi zinthu zambiri zamoyo.Panthawi imodzimodziyo, imatha kuchitapo kanthu ndi organic matter mu mabakiteriya kuti apange CO2 ndi H2O;pamene mabowo amathira OH ndi H2O adsorbed pamwamba pa TiO2 mpaka ·OH, ·OH ali ndi mphamvu ya okosijeni yamphamvu, kumenyana ndi unsaturated zomangira za organic kanthu kapena kuchotsa H ma Atomu amapanga zowonongeka zatsopano, kuyambitsa unyolo, ndipo pamapeto pake zimayambitsa mabakiteriya kuti awole.

4. Nano mkuwa,nano mkuwa oxide, nano cuprous oxide

Ma nanoparticles amkuwa opangidwa bwino ndi mabakiteriya oyipa amapangitsa kuti nanoparticles amkuwa akumane ndi mabakiteriya kudzera pakukopa kwamphamvu, ndiyeno ma nanoparticles amkuwa amalowa m'maselo a mabakiteriya, zomwe zimapangitsa kuti khoma la cell la bakiteriya liphwanyike ndipo madzi amadzimadzi amayenda. kunja.Imfa ya mabakiteriya;tinthu tating'onoting'ono ta nano-mkuwa timene timalowa m'selo nthawi yomweyo timatha kuyanjana ndi michere ya mapuloteni m'maselo a bakiteriya, kotero kuti ma enzymes amasinthidwa ndikuchotsedwa, motero amapha mabakiteriya.

Ma elemental mkuwa ndi mkuwa ali ndi antibacterial properties, kwenikweni, onse ndi ma ion amkuwa pothirira.

Zing'onozing'ono za tinthu tating'onoting'ono, zimakhala bwino ndi antibacterial effect ponena za antibacterial materials, zomwe ndizochepa kukula kwake.

5.Graphene

Ntchito ya antibacterial ya zida za graphene makamaka imaphatikizapo njira zinayi:

(1).Kuboola thupi kapena "nano mpeni" kudula njira;

(2).Kuwonongeka kwa mabakiteriya / membrane chifukwa cha kupsinjika kwa okosijeni;

(3).Transmembrane chipika choyendera ndi/kapena bakiteriya kukula chipika chifukwa ❖ kuyanika;

(4).Nembanemba ya cell imakhala yosakhazikika polowetsa ndikuwononga zinthu za cell membrane.

Malinga ndi madera osiyanasiyana okhudzana ndi zida za graphene ndi mabakiteriya, njira zingapo zomwe tazitchula pamwambapa zimayambitsa kuwononga kwathunthu kwa nembanemba zama cell (bactericidal effect) ndikuletsa kukula kwa mabakiteriya (bacteriostatic effect).
