I-Promethean Particles ibeka i-Nano-Copper yayo kuVavanyo kumlo ochasene neentsholongwane

Ezinye iintsimbi, ezifanaisilivere, igolide kunye nobhedu, zinezixhobo zokulwa ne-antibacterial kunye ne-antimicrobial;bayakwazi ukubulala okanye ukunciphisa ukukhula kwee-microorganisms ngaphandle kokuchaphazela kakhulu umkhosi.Ukuncamathela ubhedu, olona xabiso liphantsi kwezi zintathu, kwimpahla kungqineke kulucelomngeni kwixesha elidlulileyo.Kodwa kwi-2018, abaphandi abavela kwiYunivesithi yaseManchester kunye neNyakatho-ntshona yeMinzu kunye neYunivesithi yaseMzantsi-ntshona e-China baye basebenzisana ukuze benze inkqubo ekhethekileyo edibanisa ngokufanelekileyo ilaphu nge-nanoparticles yobhedu.La malaphu anokusetyenziswa njengeyunifomu yesibhedlele yamayeza okubulala iintsholongwane okanye amanye amalaphu asetyenziswa kwezonyango.

“Ezi ziphumo zintle kakhulu, kwaye ezinye iinkampani sele zibonisa umdla wokuphuhlisa obu buchwepheshe.Siyathemba ukuba singathengisa itekhnoloji ephezulu kwiminyaka embalwa.Ngoku sele siqalisile ukusebenza ekunciphiseni iindleko nokwenza inkqubo ibe lula ngakumbi,” uMbhali oyiNkokheli uGqr. Xuqing Liuwatsho.

Ngethuba lolu phononongo, i-nanoparticles yobhedu isetyenziswe kwikotoni kunye ne-polyester ngenkqubo ebizwa ngokuba, "I-Polymer Surface Grafting."I-nanoparticles yobhedu phakathi kwe-1-100 ye-nanometers ifakwe kwizinto zisebenzisa i-polymer brush.Ibrashi yepolymer yindibano yeemacromolecules (iamolekyuli eziqulethe izixa ezikhulu zeeathomu) ezibotshelelwe kwelinye icala ukuya kwi-substrate okanye kumphezulu.Le ndlela idale ibhondi eyomeleleyo yeekhemikhali phakathi kwe-nanoparticles yobhedu kunye nomphezulu welaphu.

"Kwafunyaniswa ukuba i-nanoparticles yobhedu yayilingana kwaye isasazwe ngokuqinileyo kwiindawo," ngokutsho kophando.abstract.Izinto eziphathwayo zibonise "umsebenzi osebenzayo we-antibacterial" ngokuchasene ne-Staphylococcus aureus (S. aureus) kunye ne-Escherichia coli (E. coli).Amalaphu adityanisiweyo amatsha aphuhliswe zizazinzulu zomelele kwaye ahlambeke – asabonisaantibacterialumsebenzi onganyangekiyo emva kwemijikelo ye-30 yokuhlamba.

“Ngoku ekubeni imathiriyeli yethu ehlanganisiweyo ibonisa iipropathi ezigqwesileyo zokulwa nentsholongwane kunye nokuqina, inamandla amakhulu kwizicelo zokhathalelo lwempilo lwangoku,” utshilo uLiu.

Ukosuleleka ziintsholongwane kuyingozi enkulu kwezempilo kwihlabathi jikelele.Banokusasazeka kwimpahla kunye nomgangatho ngaphakathi ezibhedlele, kuxabisa amashumi amawaka obomi kunye neebhiliyoni zeedola ngonyaka e-US kuphela.

UGregory Grass weDyunivesithi yaseNebraska-Lincoln unayowafundaisakhono sobhedu esomileyo sokubulala iintsholongwane xa sidibana nomphezulu.Ngelixa evakalelwa kukuba umphezulu wobhedu awunakuthatha indawo yezinye iindlela ezibalulekileyo zokugcina ucoceko kwiindawo zonyango, ucinga ukuba “ngokuqinisekileyo ziya kunciphisa iindleko ezinxulumene nosulelo olufunyanwa esibhedlele kwaye zithintele izifo zabantu, kwaye zisindise ubomi.”

Iintsimbi zisetyenziswe njengeii-antimicrobial agentskangangamawaka eminyaka kwaye yathatyathelwa indawo ngamayeza okubulala iintsholongwane phakathi kwenkulungwane yama-20.Ngo-2017iphephaenesihloko esithi, “Amacebo alwa neentsholongwane asekwe kwisinyithi,” uRaymond Turner weDyunivesithi yaseCalgary ubhala athi, “Ngelixa uphando ukuza kuthi ga ngoku kwii-MBAs ([i-metal-based antimicrobial]) inesithembiso esikhulu, ukuqondatoxicologykwezi zinyithi ebantwini, kwimfuyo, kwizityalo nakwi-microbial-ecosystem iyonke ayikho.”

"Ii-Nanoparticles zeCopper eZilwa neZilwa neZilwa neZibhaktheriya eziNcinciweyo ziBhlohliswe yiPolymer yeGrafting yoMphezulu Iibhrashi kuMqhaphu kunye neMathiriyeli yePolymeric,”yapapashwa kwiIjenali yeNanomaterialsngo-2018.
