Uburyo bwa Graphene Antibacterial Mechanism no Gushyira mu bikorwa

Umunwa wo mu kanwa ni microecosystem igoye ifite amoko arenga 23.000 ya bagiteri ayakoronije.Mu bihe bimwe na bimwe, izo bagiteri zishobora gutera indwara zo mu kanwa ndetse zikanagira ingaruka ku buzima muri rusange. Nyamara, ikoreshwa rya antibiotique ryerekana ibibazo bitandukanye, birimo kwangirika kw’ibiyobyabwenge byihuse, kurekura, no guteza imbere antibiyotike. Mu myaka yashize, ubushakashatsi bwibanze ku iterambere ryibikoresho byinshi hamwe na mikorobe nziza ya mikorobe ikoresheje nanomaterial. Kugeza ubu, ibikoresho bya antibacterial ya nanosilver ion n'ibikoresho bya antibacterial bishingiye kuri graphene bikoreshwa cyane ku isoko.Muri iki kiganiro, tuzamenyekanisha uburyo bwa graphene antibacterial hamwe nogukoresha mubikorwa byo koza amenyo.

 

Graphene ni karubone ebyiri-ya karubone nanomaterial igizwe na atome ya karubone itondekanye muri kasike ya mpande esheshatu hamwe na sp2 ivanze na orbitals.Ibikomokaho birimo graphene (G), graphene oxyde (GO), hamwe na graphene oxyde (rGO). Bafite imiterere yihariye yimiterere-yimiterere yimiterere nuburyo butyaye bwumubiri.Ubushakashatsi bwerekanye imiterere yihariye ya antibacterial hamwe na biocompatibilité ya graphene hamwe nibiyikomokaho. Byongeye kandi, bakora nk'abatwara imiti igabanya ubukana bwa mikorobe, bigatuma basezerana cyane mubikorwa bitandukanye mumirima ya mikorobe.

Ibyiza byagraphene ibikoresho bya antibacterial

1. Umutekano nubucuti bwibidukikije, Ntabwo ari uburozi: Gukoresha igihe kirekire nanosilver birashobora kuzamura impungenge z'umutekano kuberaubushobozi bwo kwirundanya no kwimuka. Ifumbire ya feza irashobora kwangiza cyane abantu n’inyamabere, kuko ishobora kwinjira muri mitochondriya, insoro, umwijima, sisitemu yo gutembera, n’ibindi bice byumubiri binyuze mu guhumeka. Ubushakashatsi bwerekanye ko ibice bya nanosilver bigaragaza uburozi bukomeye ugereranije nibindi byuma bya nanoparticles nka aluminium na zahabu. Kubera iyo mpamvu, Umuryango w’ubumwe bw’ibihugu by’i Burayi ukomeje kugira amakenga ku bijyanye no gukoresha ibikoresho bya mikorobe ya nanosilver.Ibinyuranye, ibikoresho bya mikorobe bishingiye kuri graphene bifashisha uburyo bwinshi bwo guhuza umubiri, nka “nano-ibyuma.” Birashobora gusenya rwose no kubuza gukura kwa bagiterinta burozi bwa shimi. Ibi bikoresho bihuza hamwe nibikoresho bya polymer, kugirango ubyemezenta gutandukanya ibintu cyangwa kwimuka. Umutekano n’umutekano wibikoresho bishingiye kuri graphene byemewe neza. Kurugero, mubikorwa bifatika, progaramu ya graphene ishingiye kuri PE (polyethylene) firime yo kubika ibiryo / imifuka yabonye ibyemezo byubahiriza ibyiciro byibiribwa nkuko Amabwiriza (EU) 2020/1245 mubumwe bw’ibihugu by’Uburayi abiteganya.
2. Guhagarara igihe kirekire: Ibikoresho bishingiye kuri Graphene byerekana guhagarara neza no kuramba, gutangaingaruka ndende ya antibicrobial kumyaka irenga 10. Ibi byemeza ko imiti yica mikorobe ikomeza kuba ingirakamaro mugihe kinini cyo kuyikoresha, bigatuma ikoreshwa mugihe kirekire mubicuruzwa by isuku yo mu kanwa.
3. Ibinyabuzima n'umutekano:Graphene, nkibikoresho bibiri-bishingiye kuri karubone, byerekana biocompatibilité n'umutekano byiza. Ihuza nibikoresho bitandukanye bishingiye kuri resin kandi irashobora gukoreshwa neza mubicuruzwa byita kumanwa bitagize ingaruka mbi kumitsi yo mumunwa cyangwa mubuzima rusange.
4. Igikorwa kinini-Igikorwa:Ibikoresho bishingiye kuri Graphene byerekana ibikorwa byinshi bya mikorobe,ishoboye kwibasira bagiteri zitandukanye, harimo Gram-nziza na Gram-mbi. Berekanyeantibacterial igipimo cya 99.9%kurwanya Escherichia coli, Staphylococcus aureus, na Candida albicans. Ibi bituma bahinduka kandi bagakoreshwa mubihe bitandukanye byubuzima bwo mu kanwa.

 

Uburyo bwa antifacterial graphene ni nkibi bikurikira:

Uburyo bwa antibacterial ya grapheneyizwe cyane nitsinda mpuzamahanga rikorana. Harimo abashakashatsi bo mu Ishuri Rikuru ry'Ubushinwa, Ikigo cy’ubushakashatsi cya IBM Watson, na kaminuza ya Columbia. Bateye intambwe igaragara mu kwiga uburyo bwimikorere ya molekile yimikoranire hagati ya graphene na bagiteri ya selile. Impapuro ziherutse kuri iyi ngingo zasohotse mu kinyamakuru “Kamere Nanotehnologiya.”

Nk’uko ubushakashatsi bwakozwe n’itsinda bubigaragaza, graphene ifite ubushobozi bwo guhungabanya ingirabuzimafatizo ya bagiteri, bigatuma ibintu biva mu nda ndetse n’urupfu rwa bagiteri. Ubu buvumbuzi bwerekana ko graphene ishobora kuba “antibiotique” idashobora kwihanganira umubiri. Ubushakashatsi bugaragaza kandi ko graphene itinjiza gusa muri selile ya bagiteri, itera kugabanuka, ahubwo ikanakuramo molekile ya fosifolipide mu buryo butaziguye, bityo igahungabanya imiterere ya membrane ikica bagiteri. Ubushakashatsi bwa microscopi ya elegitoronike bwatanze ibimenyetso bitaziguye byerekana imiterere nini yubusa muri selile ya bagiteri nyuma yo gukorana na graphene ya okiside, ishyigikira imibare. Iki kintu cyo gukuramo molekile ya lipide no guhungabana kwa membrane gitanga uburyo bushya bwa molekile yo gusobanukirwa cytotoxicity hamwe nibikorwa bya antibacterial ya nanomaterial. Bizorohereza kandi ubushakashatsi bwimbitse ku ngaruka zishingiye ku binyabuzima bya graphene nanomateriali nuburyo bukoreshwa muri biomedicine.

 

Porogaramu ya graphene antibacterial ikoreshwa munganda zoza amenyo ：

 

Bitewe nibyiza byavuzwe haruguru byibikoresho bya graphene, uburyo bwa antibacterial graphene nuburyo bukoreshwa byashimishije cyane abashakashatsi ninzobere mubikorwa bijyanye.

Graphene yoza amenyo ya antibacterial, yatangijwe naItsinda rya MARBON, koresha udusimba twabugenewe twakozwe muri graphene nanocomposite. Irashobora rero kubuza neza gukura no kubyara kwa bagiteri, bityo bikagabanya ibyago byindwara zo mu kanwa.

Ibibyimba biroroshye ariko birashobora kwihanganira, bituma habaho guhanagura neza amenyo n amenyo mugihe urinda ubuzima bwa emam na gum. Koza amenyo kandi biranga igishushanyo mbonera cya ergonomic gitanga gufata neza no gukoresha neza.

Twizera tudashidikanya ko ubu buroso bw'amenyo ya antibacterial buzatanga uburambe budasanzwe bwo kwita kumanwa. Irashobora gukuraho neza icyapa cy amenyo hamwe n imyanda. Byongeye kandi, itanga antibacterial kurinda igihe kirekire, ituma urwungano rwawe rwo mu kanwa ruguma rushya kandi rukagira ubuzima bwiza.

 

 

Umwanzuro:

Graphene yoza amenyo ya antibacterial yerekana iterambere rigezweho mugukoresha ibikoresho bya graphene mumurima wa antibacterial. Nubushobozi bwabo bunini, graphene antibacterial yoza amenyo yashyizweho kugirango ihindure ubuvuzi bwo mu kanwa, biha abantu uburambe bwiza bwo kuvura umunwa. Mugihe ubushakashatsi bwibikoresho bya graphene bugenda butera imbere, uburoso bwinyo ya graphene antibacterial izagira uruhare runini mugutezimbere ubuzima bwo mumanwa no kumererwa neza.
