Qee cov hlau, xws linyiaj, kub thiab tooj liab, muaj antibacterial thiab antimicrobial zog;lawv muaj peev xwm tua lossis txwv kev loj hlob ntawm cov kab mob uas tsis muaj kev cuam tshuam rau tus tswv tsev.Adhering tooj liab, pheej yig tshaj ntawm peb, rau khaub ncaws tau ua pov thawj nyuaj yav dhau los.Tab sis xyoo 2018, cov kws tshawb fawb los ntawm University of Manchester thiab Northwest Minzu thiab Southwest University hauv Suav teb tau sib koom ua ke los tsim cov txheej txheem tshwj xeeb uas ua rau cov ntaub npog zoo nrog tooj liab nanoparticles.Cov ntaub no tuaj yeem ua haujlwm ua cov khaub ncaws hauv tsev kho mob tshuaj tua kab mob lossis lwm yam khoom siv kho mob.

"Cov txiaj ntsig no yog qhov zoo heev, thiab qee lub tuam txhab tau nthuav tawm kev txaus siab los tsim cov thev naus laus zis no.Peb cia siab tias peb tuaj yeem ua lag luam thev naus laus zis hauv ob peb xyoos.Tam sim no peb tau pib ua haujlwm ntawm kev txo nqi thiab ua kom cov txheej txheem yooj yim dua, "Tus Thawj Kws Sau Ntawv Dr. Xuqing Liuhais.

Thaum txoj kev tshawb no, tooj liab nanoparticles tau siv rau paj rwb thiab polyester los ntawm cov txheej txheem hu ua, "Polymer Surface Grafting."Cov tooj liab nanoparticles ntawm 1-100 nanometers tau txuas nrog cov ntaub ntawv siv cov txhuam hniav polymer.Lub txhuam txhuam polymer yog ib qho kev sib dhos ntawm macromolecules (molecules uas muaj cov atoms loj) tethered ntawm ib kawg mus rau lub substrate los yog nto.Txoj kev no tau tsim cov tshuaj muaj zog ntawm cov tooj liab nanoparticles thiab cov ntaub ntaub.

"Nws tau pom tias tooj liab nanoparticles tau sib npaug thiab khov kho rau ntawm qhov chaw," raws li kev tshawb fawb.abstract.Cov ntaub ntawv kho mob tau pom tias "cov kab mob ua kom zoo" tiv thaiv Staphylococcus aureus (S. aureus) thiab Escherichia coli (E. coli).Cov ntaub ntawv tshiab sib xyaw cov khoom siv uas cov kws tshawb fawb tau tsim los kuj muaj zog thiab ntxuav tau - lawv tseem pom qhovtshuaj tua kab mobkev ua haujlwm tiv thaiv tom qab 30 lub voj voog ntxuav.

Liu hais tias "Tam sim no peb cov khoom sib xyaw ua ke nthuav tawm cov khoom siv tshuaj tua kab mob zoo thiab ua haujlwm ntev, nws muaj peev xwm loj heev rau kev siv kho mob thiab kev kho mob niaj hnub no," Liu hais.

Kab mob kab mob yog ib qho mob hnyav thoob ntiaj teb.Lawv tuaj yeem kis tau ntawm khaub ncaws thiab chaw hauv tsev kho mob, ua rau ntau txhiab tus neeg tuag thiab ntau txhiab daus las txhua xyoo hauv Asmeskas ib leeg.

Gregory Grass ntawm University of Nebraska-Lincoln muajkawmqhuav tooj liab lub peev xwm los tua microbes raws li qhov chaw sib cuag.Thaum nws xav tias qhov chaw tooj liab tsis tuaj yeem hloov lwm txoj hauv kev tu cev hauv tsev kho mob, nws xav tias lawv "yuav txo tus nqi cuam tshuam nrog kev kis mob hauv tsev kho mob thiab tiv thaiv tib neeg cov kab mob, nrog rau kev cawm neeg txoj sia."

Cov hlau tau siv los uatshuaj tua kab mobrau ntau txhiab xyoo thiab tau hloov los ntawm cov tshuaj tua kab mob hauv nruab nrab xyoo pua 20th.Hauv xyoo 2017ntawvlub npe, "Metal-based antimicrobial strategies," Raymond Turner ntawm University of Calgary sau hais tias, "Thaum kev tshawb fawb txog niaj hnub MBAs ([hlau-raws li tshuaj tua kab mob]) tau cog lus ntau, kev nkag siab ntawm covtoxicologyntawm cov hlau no ntawm tib neeg, tsiaj txhu, qoob loo thiab microbial-ecosystem tag nrho yog tsis muaj.
