Le Graphene Antibacterial Mechanism and Application

O le gutu o le gutu ose microecosystem lavelave ma sili atu i le 23,000 ituaiga o siama o loʻo nofoia.I nisi tulaga, o nei siama e mafai ona mafua tuusaʻo faʻamaʻi gutu ma e aʻafia ai le soifua maloloina atoa. Ae ui i lea, o le faʻaaogaina o vailaʻau faʻamaʻi e maua ai faʻafitauli eseese, e aofia ai le vave faʻaleagaina o vailaʻau, faʻamalolo, ma le atinaʻeina o faʻamaʻi faʻamaʻi. I tausaga talu ai nei, o le suʻesuʻega o loʻo taulaʻi atu i le atinaʻeina o mea tuʻufaʻatasia ma mea e sili ona lelei antimicrobial e faʻaaoga ai nanomaterials. I le taimi nei, o mea faʻapipiʻi faʻamaʻi faʻasolosolo nanosilver ma mea faʻamaʻi faʻamaʻi graphene e masani ona faʻaaogaina i le maketi.I totonu o lenei tusiga, o le a matou faʻalauiloaina le graphene antibacterial mechanism ma le faʻaogaina i totonu o pisinisi pulumu nifo.

 

O le Graphene o se mea e lua-dimensional carbon nanomaterial e aofia ai carbon atoms faatulagaina i se lattice hexagonal ma sp2 hybridized orbitals.O ana mea e maua mai ai e aofia ai le kalafi (G), graphene oxide (GO), ma le fa'aitiitia o le graphene oxide (rGO). O lo'o i ai i latou tulaga fa'apitoa e tolu-dimensional fa'asologa o vaila'au i luga o le eleele ma fausaga mata'i tino ma'ai. O su'esu'ega ua fa'aalia ai uiga mata'ina antibacterial ma le biocompatibility o le graphene fa'apea fo'i ma ana mea e maua mai ai. E le gata i lea, o loʻo avea i latou ma taʻavale lelei mo vailaʻau faʻamaʻi, e faʻamaonia ai mo le tele o faʻaoga i totonu o vailaʻau faʻamaʻi.

Le lelei ographene mea antibacterial

  1. Saogalemu ma le Siosiomaga, E le oona: Fa'aumi le fa'aogaina o le nanosilver e mafai ona fa'atupula'ia ai le saogalemu ona ofa'aputuga ma femalaga'iga. O le maualuga o le siliva e mafai ona matua afaina ai tagata ma mammals, aua e mafai ona ulu atu i le mitochondria, embryos, ate, toto toto, ma isi vaega o le tino e ala i le manava. O suʻesuʻega ua faʻaalia ai o vaega nanosilver e faʻaalia ai le sili atu o le oona pe a faʻatusatusa i isi nanoparticles uʻamea pei ole alumini ma auro. O le iʻuga, o loʻo faʻatumauina e le Iuni a Europa se tulaga faʻaeteete e uiga i le faʻaogaina o mea faʻamaʻi faʻamaʻi nanosilver.I ata vaaia, o mea fa'ama'i fa'ama'i fa'atatau i le graphene e fa'aogaina ai le tele o faiga fa'ama'i fa'amalosi tino, e pei o le "nano-nafi." E mafai ona latou faʻaumatia atoa ma faʻalavelaveina le tupu aʻe o siamae aunoa ma se vaila'au oona. O nei meafaitino e faʻapipiʻi faʻatasi ma mea polymer, ina ia mautinoaleai se fa'ate'a fa'aletino po'o le femalaga'iga. O le saogalemu ma le mautu o mea faʻavae graphene e mautinoa lelei. Mo se fa'ata'ita'iga, i fa'atinoga o oloa fa'atino, o ata/pepe fa'asaoina o mea'ai e fa'atatau i le graphene ua maua le fa'amaoniga mo le tausisia o mea'ai e tusa ai ma Tulafono Fa'atonutonu (EU) 2020/1245 i le Iuni a Europa.
  2. Maumau Tumau: O mea e fa'avae i luga o le graphene e fa'aalia ai le mautu ma le tumau, sauniaose aafiaga antimicrobial umi mo le silia ma le 10 tausaga. Ole mea lea e fa'amautinoa ai e tumau pea le aoga o latou mea fa'aantimicrobial i taimi fa'aumi ole fa'aoga, ma fa'apena ona talafeagai mo fa'aoga umi i oloa tumama.
  3. Biocompatibility ma le Saogalemu:O le Graphene, o se mea e lua-dimensional carbon-based material, e faʻaalia ai le biocompatibility sili ona lelei ma le saogalemu. E fetaui lelei ma le tele o mea e fa'avae resini ma e mafai ona fa'aoga saogalemu i oloa tausi gutu e aunoa ma le fa'atupuina o so'o se a'afiaga i luga ole gutu po'o le soifua maloloina atoa.
  4. Gaoioiga Alaala Lautele:O mea fa'atatau i le graphene o lo'o fa'aalia ai le tele o alaleo o le antimicrobial,mafai ona fa'atatau i le tele o siama, e aofia uma ai faʻamaʻi Gram-positive ma Gram-negative strains. Ua latou faaaliafua faatatau antibacterial o 99.9%faasaga i Escherichia coli, Staphylococcus aureus, ma Candida albicans. Ole mea lea e fa'aogaina ai ma fa'aoga i tulaga eseese ole soifua maloloina ole gutu.

 

O le graphene antibacterial mechanism e fa'apea:

Le faiga antibacterial o grapheneua su'esu'eina tele e se au galulue fa'ava-o-malo. E aofia ai tagata suʻesuʻe mai le Chinese Academy of Sciences, IBM Watson Research Center, ma Columbia University. Ua latou alualu i luma tele i le suʻesuʻeina o faiga mole mole o le fegalegaleaiga i le va o le graphene ma siama sela siama. O pepa talu ai nei e uiga i lenei autu ua lomia i le tusi talaaga "Nature Nanotechnology."

E tusa ai ma suʻesuʻega a le 'au, o le graphene o loʻo i ai le malosi e faʻalavelave ai sela sela siama, e oʻo atu ai i le tafe o mea intracellular ma oti siama. O lenei suʻesuʻega o loʻo fautua mai ai o le graphene e mafai ona avea o se "antibiotic" faaletino e le faʻasaʻo. O le suʻesuʻega o loʻo faʻaalia atili ai o le graphene e le gata e faʻapipiʻi i totonu o sela siama siama, e mafua ai le tipi, ae faʻapea foʻi ona aveese saʻo mai molelaʻau phospholipid mai le membrane, ma faʻalavelave ai le fausaga o le membrane ma fasiotia ai siama. Electron microscopy faʻataʻitaʻiga ua tuʻuina atu faʻamaoniga tuusaʻo o le tele o fausaga gaogao i sela siama siama pe a uma ona fegalegaleai ma graphene oxidized, lagolagoina le faʻatusatusaga faʻapitoa. O lenei mea mata'utia o le fa'aaogaina o le mole lipid ma le fa'alavelave fa'alavelave ua ofoina mai ai se faiga fou mole mole mo le malamalama i le cytotoxicity ma le antibacterial gaioiga o nanomaterials. O le a fa'afaigofie atili ai su'esu'ega i a'afiaga fa'aola o graphene nanomaterials ma latou fa'aoga ile biomedicine.
