Uphuhliso lwe-UV Leds phantsi kobhubhane

Usulelo olunxulumene nempilo kunye nolwasemanzini ludla ihlabathi iibhiliyoni zeerandi ngonyaka kunye namawaka obomi ngonyaka. Elinye inyathelo elibalulekileyo lokuthintela kukuvala inzala, nto leyo enokwenziwa kusetyenziswa iindlela ezahlukahlukeneyo, kuquka nemitha yokukhanya yeultraviolet (UV). Kuba iinkqubo ezifanelekileyo zokubulala iintsholongwane zinokunqanda usulelo lwezifo ezosulelayo, le mfuneko iye yangxamiseka ngakumbi ngenxa yobhubhani we-coronavirus yehlabathi.

Xa kuthelekiswa nemithombo yokukhanya ye-semiconductor, imithombo yangoku efana neebhalbhu zemercury zininzi, ziyingozi, kwaye zinenketho ezimbalwa zosetyenziso.

Yintoni? Ngaba ii-UV LEDs ?

Ii-UV-LEDs zi-LED ezivelisa imitha ye-UV ene-wavelengths ye-400 nm okanye ngaphantsi. Zahlulwe kwii-LEDs ezinzulu ze-ultraviolet (DUV-LEDs), ezinobude obungange-200-3 2 0 nm, kunye ne-ultraviolet ukukhanya-emitting diodes (NUV-LEDs), ezinobude obuphuma malunga 3 2 0-400 nm.

Ii-UV-LEDs zithembisa abaviwa kwizicelo ezininzi, kubandakanya ukutshintshwa kwezibane ze-UV, imithombo yokukhanya ye-fluorescence yokubonisa kunye nokukhanyisa, imithombo yokukhanya efanelekileyo yeemicroscopes kunye nezixhobo zokuvezwa,
imithombo yokukhanya yokuvuselela imichiza 4 esetyenziswa kwi-biotechnology, amayeza, kunye nokunyanga i-resin, imithombo yokukhanya yokuvuselela i-spectroscopy esetyenziselwa ukuchongwa kwamanqaku emali, iitshiphu ze-DNA, kunye nokubeka iliso kokusingqongileyo, kunye nemithombo yokukhanya yococeko yokubulala iintsholongwane kunye nokuvala inzala.

Ukudalwa kweUv Leds

Nakubhubhane oqhubekayo, ukubulala iifomites sisenzo esibalulekileyo sempilo yoluntu ekupheliseni usulelo lwezifo ezininzi ezosulelayo. Ngokungathandabuzekiyo kukho umdla ekudaleni itekhnoloji enokuthi ivumele ukubulawa kweentsholongwane rhoqo, okuphezulu, ngakumbi kwiindawo ezityelelwa kakhulu zikawonke-wonke, ngenxa yolwazi lwamva nje lwendima esondeleyo kunye nomdlalo wangaphakathi wokuxinana ekusasazeni intsholongwane.

Ngaphandle kokusebenza kwazo, iikhemikhali ezisebenzayo kwizibulali-ntsholongwane zemichiza yemveli kwiindawo zeklinikhi nakwilabhoratri zibeka imozulu, impilo yoluntu, kunye nemingcipheko yeziseko ezingundoqo ezenza kube nzima ukusasazwa kwazo ngokubanzi. Ukongeza, ukusebenza kwezibulala-ntsholongwane zemichiza kunokwahluka ngokuxhomekeke kumsebenzisi kunye nendlela abalandela ngononophelo ngayo iinkqubo zokucoca eziphindaphindwayo. Njengenye indlela, imitha ye-ultraviolet (UV) isetyenziswe ngokubanzi ukwenza ukuba kusebenze iintsholongwane ezininzi, kubandakanya iintsholongwane. Ukukhanya kwe-Ultraviolet kunokwenziwa ngokuzenzekelayo ukuvelisa idosi ye-germicidal ephindaphindwayo.

Intshayelelo ye Uv ikhokelela inika umgangatho ofanayo wokuphelisa ungcoliseko njengezibane zemercury zemveli, kodwa ngeenzuzo ezininzi, kubandakanywa ubulula be-retrofit kwiintlobo ngeentlobo zemithombo yokukhanya engaphezulu kwesiqhelo, kunye nesakhono sokubulala iintsholongwane.

Ukusebenza kwe-UV yokucoca kuboniswa yindlela echanekileyo yokusebenza kwayo. Ngelixa iziseko ze-thymine ezingabamelwane (okanye iziseko ze-uracil kwimeko ye-RNA) zinengxaki yokuncipha, ephazamisa ubume be-nucleotide ulandelelwano kwaye yenze "imiqobo" ekuphindaphindweni kwe-genome, iziseko ezikufutshane ze-nucleotide kwi-DNA kunye ne-RNA zifunxa ngokukodwa iifoto ze-UV.

Abaphandi babonise ukusebenza kwe-antiviral ye- Imodyuli ekhokelweyo ngokwenza iintsholongwane ezimbini: i-coronavirus 229E yomntu (hCoV-229E) kunye ne-immunodeficiency virus type 1 (HIV-1). Abaphandi babonisa ukuncitshiswa okubonakalayo kokuphindaphindeka kwentsholongwane kwimizuzwana emva kokuvezwa kwe-UV-LED ngokulinganisa iimeko eziqhelekileyo zokusingqongileyo zokusasazeka kwentsholongwane (umzekelo, ukuthimla, ukukhohlela, amathontsi egazi) kusetyenziswa iindlela zokusasazeka kwethontsi.

Uphando lwethu lunegalelo kumzimba wolwazi ekusebenziseni ii-UV-LEDs ukucoca iindawo zoluntu ezinonxibelelwano oluphezulu. Ii-UV-LEDs zimele ukhuselo olongezelelweyo, olusebenzayo kakhulu lokhuselo ngokuchasene nokusasazeka kwe-pathogen kuba azibizi kwaye kulula ukuyifaka kuluhlu lwezixhobo zokukhanya ezikhoyo, ngakumbi ngexesha lobhubhani oluqhubekayo losulelo lokuphefumla.

Iimfuno zeUV-LEDs

Ii-LED ezisithoba ze-275 nm kuluhlu lwe-3 3 kunye namashumi amabini e-380 nm LEDs kwi-4 5 uluhlu lubandakanya iiseti ezimbini ze-UV-LEDs ezibonelelweyo. Umgama phakathi kwe-LED kunye nesampuli eveziweyo yayijikeleze i-5 cm, kwaye ukuphuma kokukhanya kwe-UV ukusuka kuluhlu ngalunye ukusuka kwi-0.4 ukuya kwi-0.6 mW / cm2.

Elona xesha liphezulu lokusasazeka kwemitha laliyimizuzwana engama-30, kwaye uluhlu oludityanisiweyo lwanikezela ngethamo lilonke kwiisampulu zeradioactive ukusuka kwi-8 mJ/cm2 ukuya kwi-20 mJ/cm2. Indawo yonke ekhanyisiweyo yesixhobo yayimalunga ne-10 cm nge-20 cm, okanye i-200 cm2, inkulu kakhulu kunesampulu elayitiweyo, kwaye ifumene idosi ye-aquifer iyonke ye-1.6 J ukuya kwi-4 J.

Iziphumo kuPhando loPhuhliso lwe-UV LED phantsi kobhubhane

Imodyuli ekhokelweyo   ziye zaboniswa kolu phononongo ukuba luyasebenza ekungavuthi ntsholongwane kwi-UV-resistant, i-HIV-1, kunye ne-coronavirus yomntu 229E. Kwimeko ye-coronavirus yomntu, sibone ukuncipha kokuphindaphinda kwentsholongwane ukuya kuthi ga kwi-5.8-Log. Ekubeni umonakalo we-RNA yeyona ndlela ikhethekileyo yokucinywa imitha ye-UV kunye nokuba i-229E iyintsholongwane ye-RNA njani, abaphandi baqikelela ukuncipha okufanayo kosulelo emva kokuvezwa kwi-UV.

Nangona kunjalo, abakhange bahlole ngokuthe ngqo ukuba oku kuncitshiswa kokuphindaphindwa kwe-hCoV-229E kuhambelana nokuncipha okufanayo kosulelo. Abaphandi balumkisa ngelithi iziphumo zethu zinokusetyenziswa ngokuthe ngqo ekuvavanyeni ukusebenza kakuhle ekucoceni iintsholongwane ezingagqunywanga kuba zihlala zikwazi ukumelana ne-UV kuneentsholongwane ezigqunyiweyo.

Kolu phononongo, uphando lubonisa ukuba uyilo lwethu lwentsholongwane olukhethiweyo zonke yayizintsholongwane ezigutyungelweyo, ezikhethelwe ukuhlola nawuphi na umahluko onokwenzeka ekwamkelweni kwe-UV ngenxa yobude bejenome yentsholongwane.

Ukungasebenzi kweB. I-pumilus spores, eyaziwa ngokuba nenqanaba eliphezulu lokomelela kwe-UV, yaboniswa kulingo lwethu. Abaphandi bathi obu inokuba bubungqina bokuqala bokuba iintsholongwane ezingagqunywanga zinokuthi zingasebenzi kukukhanya kwe-UV. Kuye kwacetywa ukuba kusetyenziswe i-B. i-pumilus spores njengendawo yokuma yokuvavanya ukungasebenzi kwe-rotavirus yomntu engagqunywanga ngemitha ye-UV.

Ungayithenga phi i-UV yakho ye-LED ukusuka?

Ngokuqhutywa ngokupheleleyo kwemveliso, umgangatho ongaguqukiyo kunye nokuthembeka, kunye neendleko ezifikelelekayo, Tianhui Electronics   ebesebenza kwi Isisombululo se-UV LED   imarike. UV   L abavelisi be-ed   yiza kwi-UVA, UVB, kunye ne-UVC yamaza. Ngokusekwe kwiinkqubo ezahlukeneyo ze-UV, iintlobo ezininzi ze Uv ikhokelela   ziyafumaneka, ezifana UV LED   imigibe yeengcongconi, UV LED   iibhotile zokuvala inzala, kunye nenqwelo-mafutha UV LED   abacoci bomoya.

Namhlanje Isisombululo se-UV LED   isetyenziselwa ukuphelisa ipathogen emoyeni kunye nokucocwa kwefotocatalytic kwimoto UV LED   abacoci bomoya.

Ngetekhnoloji ye-UVC yokuphelisa iintsholongwane ze-LED, engeyotyhefu kunye ne-mercury-free, ngaphandle kwemitha okanye ivumba, izinga lokubulala iintsholongwane kwi-UVC LED iikomityi zokubulala iintsholongwane ezinokufikelela phezulu ukuya kuma-99%.

Xa isetyenziswe kwi-a UV LED   umgibe weengcongconi, Ii-LED ze-UV ngesiphumo esiphezulu se-optical sinokutsala iingcongconi ngokufanelekileyo kwindawo enkulu. Baphinde bavelise i-CO2 nge-photocatalytic reaction kunye ne-TiO2 egqunywe kwicala langaphakathi lophahla oluphezulu.
