Puas yog UV STERILIZATION muaj txiaj ntsig rau cov kab mob thiab kab mob?

UV sterilization ua haujlwm zoo li cas? Nws puas tua kab mob thiab kab mob? Cov txiaj ntsig thiab qhov tsis zoo yog dab tsi? Thaum tib neeg xav txog qhov ua qias tuaj ntawm lawv lub xov tooj ntawm tes, cov no yog cov lus nug uas kuv nquag hnov ​​thaum ua haujlwm hauv microbiology txoj haujlwm. Tej zaum koj yuav xav tsis thoob tias UV sterilization cov khoom puas tsim nyog sim ua ntau thiab ntau ntawm lawv nkag mus rau hauv khw. Yog li cia peb pib!

Txij li thaum nruab nrab ntawm lub xyoo pua 20th, UV hluav taws xob tau siv los ua kom tsis muaj menyuam thiab tua kab mob. Nws txhim khu kev ua neej ntev (ntau txhiab teev) thiab txo qhov loj me (xws li UV LED vs. qauv UV qhov muag teev) tau nce nws cov ntawv thov ua tsaug rau kev tsim kho thev naus laus zis, tshwj xeeb hauv UV qhov muag teev lawv tus kheej. Nws yog siv los ntxuav ntau qhov chaw sib txawv, suav nrog dej, huab cua, txiv hmab txiv ntoo, zaub, khoom siv kho mob, ntsiav tshuaj computer, thiab cov khoom ua si.

Tsis yog txhua qhov UV wavelengths ua tau zoo rau UV sterilization. Vim li cas qhov ntawd tseem ceeb? Kev hais lus, ultraviolet (UV) yog hais txog ib pawg ntawm cov hluav taws xob hluav taws xob nrog lub voj voog luv luv (ntau zaus thiab lub zog) dua li lub teeb pom kev zoo nkauj. UV stands rau "dhau violet" thiab piav qhia txog ntau yam ntawm electromagnetic nthwv dej. Peb pawg ntawm UV yog qhov txawv los ntawm kev txo cov wavelengths thiab nce zog. UVA, UVB, thiab UVC yog peb. Tsuas yog UVC (100–280 nm) muaj lub zog txaus rau UV kom tsis muaj menyuam kom tua cov kab mob zoo. Xyuas kom tseeb tias UV sterilization khoom koj xaiv los siv hauv koj lub tsev lossis qhov chaw ua lag luam ua haujlwm ntawm UVC wavelength, uas nyob nruab nrab ntawm 100 thiab 280 nanometers.

Puas yog UV sterilization zoo tiv thaiv kab mob thiab kab mob? Yog, thiab txawm ntau cov kab mob, yog cov lus teb ceev. Tag nrho cov khoom noj uas muaj kab mob, lub ntuj microbiota, pwm, thiab cov poov xab tuaj yeem raug rhuav tshem los ntawm UVC ntawm 254 nm, raws li kev tshawb fawb. Txhua hom kab mob yuav tsum muaj ntau lub sijhawm los tua vim lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov duab uas cuam tshuam ntau npaum li cas UV teeb lawv nqus.

UV sterilization koom nrog dab tsi? Kuv zoo siab koj nug! UV sterilization, qee zaum hu ua UV tshuaj tua kab mob los yog ultraviolet germicidal irradiation (UVGI), tiv thaiv cov kab mob los ntawm kev tsim tawm los ntawm kev sib cais cov tshuaj lom neeg tshwj xeeb thiab jumbling cov qauv ntawm DNA, RNA, thiab cov proteins. Ib microbe uas tsis tuaj yeem rov tsim dua yog suav tias yog tuag vim nws tsis kis tau thiab tsis tuaj yeem tsim tawm hauv tus tswv tsev.

"Tuag." Qhov ntawd yog qhov zoo tagnrho, kuv xav. Nws yuav siv sij hawm ntev npaum li cas rau qhov khoom phem no kom ncav cuag qhov "tuag"? Wb sib tham txog kev puas tsuaj. Txij li UV sterilization siv UVC hluav taws xob los rhuav tshem cov proteins, cov nqi ntawm lub zog siv, uas cuam tshuam los ntawm lub sij hawm raug thiab qhov kev ncua deb ntawm lub teeb ci, txiav txim siab seb cov txheej txheem yuav ua li cas. Piv txwv li, kev ua kom tsis muaj menyuam ntawm E. coli-loj petri phaj siv sijhawm tsuas yog 1-2 feeb yog tias siv lub teeb UV thiab tuav ib nti saum lub tais.1 Nws tuaj yeem siv li 5 mus rau 10 feeb kom tsis muaj menyuam cov khoom siv phais hauv nruab nrab UV lub thawv. Ib qho kev pom zoo yog 30 feeb rau kev ua kom tsis muaj menyuam hauv 8-ko taw biosafety txee hauv chav kuaj.

Lwm qhov tsis zoo ntawm UV sterilization yog cov proteins thiab DNA / RNA raug mob hnyav heev los ntawm UVC uas cov khoom siv kho mob tsis tuaj yeem tsim siv lawv. Piv txwv li, thaum cov kab mob ua kom tsis muaj menyuam nrog UVC, cov proteins saum npoo tau raug puas tsuaj loj, ua rau nws tsis tuaj yeem siv cov kab mob ua cov tshuaj tiv thaiv kom tshem tawm cov lus teb xav tau. Hauv cov khoom lag luam biomedical, cov kab mob ntawm cov kab mob saum npoo yog khaws cia thaum cov kab mob ua haujlwm tsis zoo siv cov txheej txheem "UV inactivation". Vim tias peb xav siv cov kab mob sib kis tsis zoo ntawm cov kab mob UV kho rau lub hom phiaj biomedical, xws li tsim cov tshuaj tiv thaiv kab mob, qhov no kuj yog cov txheej txheem uas peb siv rau peb cov khoom siv UV inactivated purified virus.

Thaum kawg, UV ua kom tsis muaj menyuam yog lwm txoj hauv kev zoo txawm tias koj tab tom nrhiav lub tshuab los ntxuav koj lub worktops, ib lub wand los ntxuav koj lub txaj hauv tsev so qias neeg, lossis ib lub cuab yeej los ntxuav koj cov khau stale. Thiab tsis txhob hnov ​​​​qab tias nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov chaw tsim khoom cov lus qhia rau lub teeb-qhov deb, lub sij hawm raug, thiab kev ntsuas kev nyab xeeb rau txhua yam khoom koj yuav.
