[Ukwenziwa inzalo kwe-UVLED] Isayensi Edumile Yokubulala Amagciwane Kwe-UV LED Sterilization

Imisebe ye-Ultraviolet iyigagasi lokukhanya lamandla aphezulu elinamandla amakhulu, iso lenyama alikwazi ukubonwa. Ubude bayo begagasi bungaphansi kuka-400nm, obungaphandle kohlangothi olungaphandle lwe-spectrum ultraviolet end, ngakho ibizwa ngokuthi imisebe ye-ultraviolet. Ngobubanzi be-wavelength ihlukaniswe yaba yi-UV-A (320nm 400nm), UV-B (275nm 3 2 0 n m), UV-C (2 0 nm 2 7 5 nm), UV-D (100nm 200nm) amane Le bhendi, lapho i-A , B, no-C, amabhande amathathu abizwa nangokuthi imisebe ye-ultraviolet ekhishwa amagciwane. Amabhendi amathathu ka-A, B, kanye no-C anomphumela othile wokubulala amagciwane, ikakhulukazi ngomthelela ongcono kakhulu wokubulala amagciwane ngebhendi engu-C. Ithiyori ye-quantum ekhanyayo ikholelwa ukuthi ukukhanya kuyindlela ekhethekile yokuhamba kwezinto ezibonakalayo. I-wavenge ngayinye ye-253.7nm UV photon inamandla angu-4.9EV. Ukukhipha amagciwane kanye nokufakwa inzalo kolayini we-UV emanzini ngokuyinhloko ubukhulu beza beza beza (254nm) bokumuncwa kwe-nucleic acid (DNA). I-DNA ingakwazi ukumunca imisebe ye-ultraviolet ene-high-energy, ibangele ukuhlukaniswa okusekelwe kwe-alkali eduze, futhi yakhe i-pyrimidine dimer; Ikhophi ye-Nucleic acid kanye ne-protein expression iholela ku-apoptosis. Njengamanje, ucwaningo lukhawulelwe ocwaningweni lwemisebe ye-ultraviolet evamile, futhi i-UV-LED njengohlobo olusha lwenqubo yokubulala amagciwane ingase yehluke kakhulu kumshini ovamile wokubulala amagciwane. Ngakho - ke. Ukuze uthole ulwazi olwengeziwe, wamukelekile kusizindalwazi esisemthethweni http:///show-23-155.html
