Antibacterial
Nekuvandudzwa kwesainzi uye tekinoroji uye nekuvandudzwa kwemararamiro evanhu, kudiwa kwevanhu kwezvinhu zveantibacterial uye zvigadzirwa zvicharamba zvichiwedzera.Kuti uvandudze hutano hwevanhu, kuvandudza nharaunda yekugara uye yekushanda, kutsvagisa uye kusimudzira kwezvitsva, zvepamusoro-soro, zvisina muchetura, zvisinganhuwi uye zvinorwisa mabhakitiriya zvinhu zvine antibacterial zvimiro zvinogara kwenguva refu zvave ikozvino hotspot yekutsvaga.Silver antibacterial zvinhu zvine hunhu hwepamusoro-soro, yakafara spectrum, yakaderera toxicity, isinganakidze, isina-kusvibisa nharaunda, chengetedzo uye kuchengetedzwa kwezvakatipoteredza, nezvimwewo, uye iri kuve imwe yekutanga sarudzo antibacterial agents.
Sananomaterial, nanosilver ine vhoriyamu mhedzisiro, mhedzisiro, quantum saizi maitiro uye macroscopic quantum tunnel athari, uye ine yakakura budiriro mukana uye kukosha kwekushandisa muminda ye superconductivity, photoelectricity, antibacterial, uye catalysis.
Mhando mbiri dzebhakitiriya, Escherichia coli uye Staphylococcus aureus, dzakasarudzwa sevamiririri vehutano uye huwandu hwekuonekwa kwehutachiona hwehutachiona hweiyo yakagadzirwa nano-silver colloid.Mhedzisiro yekuedza yakasimbisa kuti nano sirivheri colloid inogadzirwa naHongwu Nano ine yakanaka antibacterial properties kurwisa Gram-negative bacteria, Gram-positive bacteria uye mold.Uye iyo antibacterial properties inogara kwenguva refu.
Iko kushandiswa kukuru kwe nano sirivheri colloid hakugumiri kune zvinotevera:
Mushonga: antibacterial uye anti-infection, kugadzirisa uye kuvandudzwa kwematishu;
Electronics: conductive coating, conductive inki, chip packaging, electrode paste;
Zvinodiwa zvezuva nezuva: anti-static, anti-bacterial coating / firimu;
Catalytic zvinhu: mafuta cell catalyst, gasi chikamu catalyst;
Zvinhu zvekutsinhanisa kupisa;electroplating coating materials.
Mhoteredzo yekugara ine hutano yave chinangwa chevanhu.Nokudaro, utachiona hwezvakatipoteredza hunokuvadza hutano hwevanhu hunokwezvawo pfungwa dzevanhu.Antibacterial activities
inogara iri basa rakakosha rekuti vanhu vadzivirire hutano hwedu.Nekuvandudzwa kwesainzi uye tekinoroji, nano antibacterial zvinhu zvinoshandiswa zvakanyanya mukucheneswa kwemhepo, kurapa kwetsvina,
zvigadzirwa zvepurasitiki, zvekuvaka coatings, hutano hwehutano uye mamwe minda.
Kurongwa kwezvimwe zvinonyanya kushandiswa nano antibacterial zvinhu
1. Metal nano antibacterial zvinhu
a.Silver nanoparticles (muchimiro chehupfu)
b.Silver nanoparticles dispersion(mumvura fomu)
c.Rudzi rusina ruvara rwakajeka nano sirivheri kupararira (mumvura fomu)
2.Metal oxide nano antibacterial zvinhu
a.ZnO Zinc oxide nanoparticles
b.CuO Copper oxide nanoparticles
c.Cu2O Cupous oxide nanoparticles
d.TiO2 Titanium dioxide nanoparticles (photocatalysis)
3.Core-shell nanoparticles
Ag/TiO2 Nanoparticles,Ag/ZnO nanoparticles.etc
Kushandiswa kwe nano antibacterial zvinhu
1. Nano antibacterial coating
Iyo antibacterial uye mildewproof coating, mhepo yekuchenesa coating uye antifouling yekuzvichenesa coating yakagadziridzwa nekuwedzera zvakataurwa pamusoro apa nano antibacterial zvinhu mujasi, uye inoshamisa yekunatsa mhedzisiro yakawanikwa.
2. Nano antibacterial mapurasitiki
Kuwedzerwa kwechikamu chiduku chemishonga inorwisa mabhakitiriya inogona kupa purasitiki yenguva refu inorwisa mabhakitiriya uye bactericidal kukwanisa.Plastic antibacterial material yakawedzera huwandu hwe1% inogona kuva mupurasitiki kwenguva refu - antibacterial uye sterilization.
Kushandiswa kwemapurasitiki anorwisa utachiona kunosanganisira midziyo yechikafu, kutaurirana nemagetsi, midziyo yemumba, zvekuvakisa, zvemuhofisi, matoyi, hutano, uye zvigadzirwa zvemumba.
3. Nano antibacterial fibers
Nekuti faibha inogona kutora ma microorganisms akawanda, kana tembiricha yakakodzera, ma microorganisms anowedzera nekukurumidza, nekudaro achikonzera kukuvadza kwakasiyana kumuviri wemunhu.
Textile fiberantibacterial chinhu chakakosha chekusimbisa hutano hwevanhu.
4. Nano antibacterial ceramics
Iyo antibacterial pamusoro peceramic tableware inowanikwa nekuwedzera nano antibacterial zvinhu.
5. Nano antibacterial building materials
Zvivakwa zvemazuva ano zvine kusimba kwemhepo kwakanaka, kusakwana kwekudzivirira kupisa uye kufefetera, uye madziro anogona kunge aine dova uye kunyorova, izvo zvinopa mamiriro akanaka ekubereka uye kuwanda.
Kushandiswa kweantibacterial zvivakwa zvekuvaka, antibacterial coatings uye antibacterial pendi zvinogona kudzikisa zvakanyanya chiyero chekupona kwebhakitiriya pane fenicha.
madziro emukati uye mhepo yemukati, inova nzira inoshanda yekudzikisa mukana wehutachiona hwehutachiona hwehutachiona uye kubata hutachiona.
