I-antibacterial
Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuthuthukiswa kwamazinga okuphila kwabantu, isidingo sabantu sezinto ezilwa namagciwane kanye nemikhiqizo sizoqhubeka nokwanda.Ukuze kuthuthukiswe impilo yomuntu, kuthuthukiswe indawo yokuhlala kanye nokusebenza, ucwaningo nokuthuthukiswa kwezinto ezintsha, ezisebenza kahle kakhulu, ezingenabuthi, ezingenaphunga nezibulala amagciwane ezinezakhiwo ezihlala isikhathi eside zokulwa namagciwane seziphenduke indawo yocwaningo lwamanje.Izinto zesiliva ze-antibacterial zinezici zokusebenza kahle okuphezulu, i-spectrum ebanzi, ubuthi obuphansi, imvelo enganambitheki, engangcolisi, ukuphepha nokuvikelwa kwemvelo, njll., futhi iba enye yezinto zokuqala zokukhetha ama-antibacterial agents.
Njenge-nanomaterial, i-nanosilver inomphumela wevolumu, umphumela ongaphezulu, umphumela wesayizi we-quantum kanye nomphumela we-macroscopic quantum tunnel, futhi inamandla amakhulu okuthuthuka kanye nenani lesicelo emikhakheni ye-superconductivity, photoelectricity, antibacterial, kanye ne-catalysis.
Izinhlobo ezimbili zamabhaktheriya, i-Escherichia coli ne-Staphylococcus aureus, zakhethwa njengabameleli bokutholwa kwekhwalithi nobuningi bezakhiwo ze-antibacterial ze-nano-silver colloid elungisiwe.Imiphumela yokuhlolwa iqinisekise ukuthi i-nano silver colloid ekhiqizwe i-Hongwu Nano inezindawo ezinhle zokulwa namagciwane ngokumelene nama-Gram-negative bacteria, amagciwane e-Gram-positive kanye nezibungu.Futhi izakhiwo ze-antibacterial zihlala isikhathi eside.
Ukusetshenziswa okuyinhloko kwe-nano silver colloid akugcini kulokhu okulandelayo:
Umuthi: i-antibacterial kanye ne-anti-infection, ukulungiswa nokuvuselelwa kwezicubu;
I-elekthronikhi: i-conductive coating, inki yokuqhuba, ukupakishwa kwe-chip, ukunamathisela kwe-electrode;
Izidingo zansuku zonke: i-anti-static, i-anti-bacterial coating/ifilimu;
Izinto zokwakha: i-fuel cell catalyst, i-gas phase catalyst;
Izinto zokushintshanisa ukushisa;izinto zokugqoka ze-electroplating.
Indawo yokuhlala enempilo isibe umgomo wabantu.Ngakho-ke, ama-microorganisms emvelo alimaza impilo yomuntu nawo aheha ukunaka kwabantu.Imisebenzi yokulwa namagciwane
zihlale ziwumsebenzi obalulekile kubantu ukuvikela impilo yethu.Ngokuthuthukiswa kwesayensi nobuchwepheshe, izinto ze-nano antibacterial zisetshenziswa kabanzi ekuhlanzeni umoya, ekuhlanzeni indle,
imikhiqizo yepulasitiki, ezinengilazi yezakhiwo, impilo yezokwelapha kanye neminye imikhakha.
Ukuhlukaniswa kwezinye zezinto ezivame ukusetshenziswa kakhulu ze-nano antibacterial
1. Metal nano impahla elwa namagciwane
I-a.Silver nanoparticles(ngefomu lempushana)
b.Silver nanoparticles dispersion(in liquid form)
c.I-nano silver dispersion engenambala engenambala (isesimweni esiwuketshezi)
2.Metal oxide nano impahla elwa namagciwane
a.ZnO Zinc oxide nanoparticles
b.I-CuO Copper oxide nanoparticles
c.Cu2O Cupous oxide nanoparticles
d.TiO2 Titanium dioxide nanoparticles(photocatalysis)
3.Core-shell nanoparticles
I-Ag/TiO2 Nanoparticles,Ag/ZnO nanoparticles.etc
Ukusetshenziswa kwe-nano antibacterial materials
1. I-Nano antibacterial enamathela
I-antibacterial and mildewproof coating, i-air purification coating kanye ne-antifouling self-cleaning coating yathuthukiswa ngokungeza izinto ezibalulwe ngenhla ze-nano antibacterial embotsheni, futhi kwatholakala umphumela wokuhlanza ophawulekayo.
2. Amapulasitiki e-antibacterial e-Nano
Ukwengezwa kwenani elincane lezinto ezilwa namagciwane kunganikeza ipulasitiki ikhono lesikhathi eside lokulwa namagciwane kanye ne-bactericidal.Impahla yepulasitiki elwa namagciwane isamba esingu-1% singaba sepulasitiki isikhathi eside sokulwa namagciwane kanye nokuvala inzalo.
Izicelo zamapulasitiki ezilwa namagciwane zihlanganisa izinto zikagesi zokudla, ukuxhumana ngogesi, izinto zasendlini, izinto zokwakha, izinto zasehhovisi, amathoyizi, ukunakekelwa kwezempilo, kanye nemikhiqizo yasendlini.
3. I-Nano antibacterial fibers
Ngenxa yokuthi i-fiber ingakwazi ukumunca ama-microorganisms amaningi, uma izinga lokushisa lifanelekile, ama-microorganisms azokhula ngokushesha, ngaleyo ndlela abangele ukulimala okuhlukahlukene emzimbeni womuntu.
I-textile fiberantibacterial iyisixhumanisi esibalulekile sokuqinisekisa impilo yabantu.
4. I-Nano antibacterial ceramics
I-antibacterial surface ye-ceramic tableware ibonakala ngokungeza izinto zokulwa namagciwane ze-nano.
5. Izinto zokwakha ze-Nano antibacterial
Izakhiwo zesimanje zinomoya omuhle oqinile, ukuvikela ukushisa okwanele kanye nokungena komoya, futhi izindonga zingase zibe namazolo futhi zibe nomswakama, okunikeza izimo ezikahle zokuzala nokwanda.
Isikhunta nezinye izinambuzane.Ukusetshenziswa kwezinto zokwakha ezilwa namagciwane, izimbotshana ezilwa namagciwane kanye nopende obulala amagciwane kunganciphisa kakhulu izinga lokusinda kwamagciwane endaweni yefenisha,
izindonga zasendlini kanye nomoya wangaphakathi, okuyindlela ephumelelayo yokunciphisa amathuba okutheleleka kwe-bacterial cross kanye nokutheleleka kokuxhumana.
