ʻO ka Graphene Antibacterial Mechanism and Application

ʻO ka waha waha he microecosystem paʻakikī me ka ʻoi aku o 23,000 mau ʻano bacteria e noho ana.I kekahi mau kūlana, hiki i kēia mau bacteria ke hoʻoulu pololei i nā maʻi waha a hiki i ka hopena i ke olakino holoʻokoʻa. Eia nō naʻe, ʻo ka hoʻohana ʻana i nā lāʻau lapaʻau e hōʻike i nā pilikia like ʻole, e like me ka hōʻemi wikiwiki ʻana i ka lāʻau lapaʻau, hoʻokuʻu, a me ka hoʻomohala ʻana i ke kūʻē antibiotic. I kēia mau makahiki i hala iho nei, ua neʻe ka manaʻo noiʻi i ka hoʻomohala ʻana i nā mea hoʻohui me nā waiwai antimicrobial maikaʻi me ka hoʻohana ʻana i nā nanomaterials. I kēia manawa, hoʻohana pinepine ʻia nā mea antibacterial ion-ion-based nanosilver a me nā mea antibacterial graphene-based i ka mākeke.Ma kēia ʻatikala, e hoʻolauna mākou i ka mīkini antibacterial graphene a me ka hoʻohana ʻana i ka ʻoihana niho niho.

 

ʻO Graphene kahi kalapona nanomaterial ʻelua-dimensional i haku ʻia me nā ʻātoma kalapona i hoʻonohonoho ʻia i loko o kahi lattice hexagonal me nā orbital hybridized sp2.ʻO kāna mau huaʻōlelo he graphene (G), graphene oxide (GO), a me ka graphene oxide hoʻemi (rGO). Loaʻa iā lākou nā ʻano kemika ʻokoʻa ʻekolu-dimensional a me nā hoʻolālā lihi kino ʻoi. Eia kekahi, lawelawe lākou ma ke ʻano he mea lawe kūpono no nā mea antimicrobial, e hoʻohiki nui ana iā lākou no nā noi like ʻole i nā māla antimicrobial waha.

ʻO nā pono onā mea antibacterial graphene

1. Palekana a me ke Kaiapuni, Non-toxic: ʻO ka hoʻohana lōʻihi ʻana o ka nanosilver hiki ke hāpai i nā hopohopo palekana ma muli ohiki ke hōʻiliʻili a me ka neʻe ʻana. Hiki ke hoʻopōʻino loa i nā kānaka a me nā mammals ke kiʻekiʻe o ke kālā, no ka mea hiki ke komo i ka mitochondria, embryos, ate, ʻōnaehana kaʻa, a me nā ʻāpana ʻē aʻe o ke kino ma o ka hanu ʻana. Ua hōʻike ʻia nā haʻawina e hōʻike ana nā ʻāpana nanosilver i ka ʻawaʻawa i hoʻohālikelike ʻia me nā nanoparticles metala e like me ke alumini a me ke gula. ʻO ka hopena, mālama ka European Union i kahi kūlana makaʻala e pili ana i ka hoʻohana ʻana i nā mea antimicrobial nanosilver.He ʻokoʻa, hoʻohana nā mea antimicrobial i hoʻokumu ʻia i ka graphene i nā ʻano hana sterilization kino synergistic, e like me "nano-knives." Hiki iā lākou ke luku loa a pale i ka ulu ʻana o ka bacteriame ka ʻole o nā mea ʻona. Hoʻohui maikaʻi kēia mau mea me nā mea polymer, i mea e hōʻoia aiʻaʻohe mea hoʻokaʻawale a neʻe paha. Hoʻopaʻa maikaʻi ʻia ka palekana a me ka paʻa o nā mea graphene. No ka laʻana, i nā noi huahana pono, ua loaʻa i nā kiʻiʻoniʻoni mālama meaʻai ʻo PE (polyethylene) e pili ana i ka graphene i ka palapala hōʻoia no ka hoʻokō ʻana i ka meaʻai e like me Regulation (EU) 2020/1245 i ka European Union.
2. Paʻa no ka wā lōʻihi: Hōʻike nā mea i hoʻokumu ʻia i ka graphene i ke kūpaʻa a me ka lōʻihi, hāʻawihe hopena antimicrobial lōʻihi no nā makahiki he 10. Mālama kēia i kā lākou mau waiwai antimicrobial i ka hoʻohana ʻana i nā manawa lōʻihi, e kūpono ana iā lākou no nā noi lōʻihi i nā huahana hoʻomaʻemaʻe waha.
3. Biocompatibility a me ka palekana:ʻO Graphene, ma ke ʻano he ʻelua-dimensional carbon-based material, hōʻike i ka biocompatibility maikaʻi loa a me ka palekana. He kūpono ia me nā ʻano mea like ʻole e pili ana i ka resin a hiki ke hoʻohana pono ʻia i nā huahana mālama waha me ka ʻole o ka hopena ʻino i nā ʻiʻo waha a i ʻole ke olakino holoʻokoʻa.
4. Haʻawina Launa Nui:Hōʻike nā mea hana graphene i ka hana antimicrobial ākea ākea,hiki ke hoʻopaʻa i nā ʻano bacteria, e pili ana i nā kānana Gram-positive a me Gram-negative. Ua hōʻike lākouka helu antibacterial o 99.9%kū'ē iā Escherichia coli, Staphylococcus aureus, a me Candida albicans. ʻO kēia ka mea i maʻalahi a kūpono i nā kūlana olakino waha.

 

ʻO ka hana antibacterial graphene penei:

ʻO ka hana antibacterial o grapheneua aʻo nui ʻia e kahi hui hui honua. Me nā mea noiʻi mai ka Chinese Academy of Science, IBM Watson Research Center, a me Columbia University. Ua holomua nui lākou i ke aʻo ʻana i nā ʻano molekala o ka pilina ma waena o ka graphene a me nā membrane cell bacteria. Ua paʻi ʻia nā pepa hou e pili ana i kēia kumuhana ma ka puke pai "Nature Nanotechnology."

Wahi a ka noiʻi a ka hui, hiki i ka graphene ke hoʻopau i nā membrane cell bacteria, e alakaʻi ana i ka leakage o nā mea intracellular a me ka make bacteria. Hōʻike kēia ʻike e hiki i ka graphene ke lawelawe ma ke ʻano he "antibiotic" kino. Hōʻike hou ka haʻawina ʻaʻole hoʻokomo wale ka graphene iā ia iho i loko o nā membrane cell bacteria, e hōʻoki ana, akā lawe pū kekahi i nā molekole phospholipid mai ka membrane, a laila e hoʻopau ai i ke ʻano o ka membrane a pepehi i ka bacteria. Ua hāʻawi nā hoʻokolohua microscopy electron i nā hōʻike pololei o ka nui o nā mea ʻole i loko o nā membrane cell bacterial ma hope o ka launa pū ʻana me ka graphene oxidized, e kākoʻo ana i nā helu theoretical. Hāʻawi kēia ʻano o ka ʻili mole lipid a me ka hoʻopau ʻana i ka membrane i kahi mīkini molekala hou no ka hoʻomaopopo ʻana i ka cytotoxicity a me ka hana antibacterial o nā nanomaterials. E hoʻomaʻamaʻa hoʻi ia i ka noiʻi hou ʻana i nā hopena biological o nā nanomaterials graphene a me kā lākou noi i ka biomedicine.

 

ʻO ka noi antibacterial graphene i ka ʻoihana niho niho:

 

Ma muli o nā pono o luna o ka graphene composite material, graphene antibacterial mechanism a me ka hoʻohana ʻana i hoihoi nui mai ka poʻe noiʻi a me nā loea i nā ʻoihana pili.

Pahu niho antibacterial Graphene, hoʻolauna ʻia eʻO ka hui MARBON, e hoʻohana i nā bristles i hoʻolālā kūikawā ʻia i hana ʻia mai nā mea graphene nanocomposite. No laila hiki iā ia ke pale pono i ka ulu a me ka hana hou ʻana o ka bacteria, a laila e hōʻemi ana i ka hopena o nā maʻi waha.

He palupalu nā bristles akā hiki ke hoʻomaʻemaʻe ʻia i ka hoʻomaʻemaʻe ʻana i nā niho a me nā ʻāʻī ʻoiai e pale ana i ka enamel a me ke olakino gum. Hāʻawi pū ka pulupulu niho i kahi hoʻolālā lima ergonomic e hāʻawi i kahi ʻoluʻolu a me ka hoʻohana maʻalahi.

Ke manaʻoʻiʻo nei mākou e hāʻawi kēia pulupulu niho antibacterial i kahi ʻike mālama waha. Hiki iā ia ke wehe pono i ka plaque niho a me nā ʻōpala meaʻai. Hoʻohui ia, hāʻawi ia i ka pale antibacterial lōʻihi, e hōʻoiaʻiʻo ana i kou lua waha e noho hou a olakino.

 

 

Ka hopena:

Hōʻike nā pulupulu niho antibacterial Graphene i ka holomua hou loa i ka hoʻohana ʻana i nā mea graphene ma ke kahua antibacterial. Me ko lākou mana nui, ua hoʻonohonoho ʻia nā pulupulu niho antibacterial graphene e hoʻololi i ka mālama waha, e hāʻawi ana i nā poʻe me kahi ʻike mālama waha ʻoi aku ka olakino a ʻoluʻolu. Ke holomua nei ka noiʻi ʻana i nā mea graphene, e pāʻani nui ana nā pulupulu niho antibacterial graphene i ka hāpai ʻana i ke olakino waha a me ka maikaʻi.
