Iiprobe zovavanyo zincinci ze-DNA ezinemisonto enye okanye i-RNA fragments (malunga ne-20 ukuya kwi-500 bp) esetyenziselwa ukufumanisa ukulandelelana kwe-nucleic acid ehambelanayo.I-DNA enemisonto ephindwe kabini idityaniswe ngokufudumeza ukuze ibe ngumsonto omnye, kwaye emva koko ibhalwe ngeradioisotopes (idla ngokuba yi-phosphorus-32), idayi ye-fluorescent, okanye i-enzymes (efana ne-horseradish peroxidase) ukuze ibe yi-probes.I-Phosphorus-32 idla ngokudityaniswa kwiqela le-phosphate yenye yee-nucleotide ezine ezenza i-DNA, kunye nedayi ze-fluorescent kunye ne-enzymes zidibene ngokulandelelana kwi-nucleic acid.
Ngoku kwindawo yovavanyo, iprobe yovavanyo isetyenziswa njengendawo ephakathi, iprobe ibekwe ecasing, intloko yeprobe inxibelelana nento eza kuvavanywa, kwaye ucingo olukhokelayo lwecasing kwelinye icala luqhuba umqondiso, kwaye uphawu olufunyenweyo lukumvavanyi.Ngokomzekelo, i-resistor isebenzisa umthombo wangoku ukubala ukuhla kwamandla ombane kwi-probe, kwaye i-capacitor isebenzisa umthombo we-voltage rhoqo ukubala ukuthambeka kwexesha lokutshaja kwiifrikhwensi ezahlukeneyo.I-probe ineempawu zokusetyenziswa ngokuqhubekayo xa yenziwe kwi-fixture, kwaye ixabiso aliphezulu.Usetyenziswe ngokubanzi kwindawo yokuvavanya.
Kukho iintlobo ezininzi zeentloko zeprobe yovavanyo.Isizathu esona sizathu kukuba amanqaku okuvavanya ahlukeneyo afuna iindidi zeentloko ezahlukeneyo.Umzekelo, iinyawo zediphu zisebenzisa iindidi zentloko yezipho ezininzi, amanqaku ovavanyo asebenzisa iintloko ezitsolo, ezingqukuva okanye ezisicaba, kwaye izikhonkwane ze-IC zisebenzisa iplum blossom.Imilo yentloko, njl.njl zonke zikhethwe ngabasebenzi abanamava emveliso ngokweenxalenye kwi-PCB egqityiweyo.
I-Nanometering kuphela ukomelezwa kwemathiriyeli yeprobe, kwaye akukho mpembelelo kuluhlu lovavanyo.Ukuba unomdla, impembelelo kuluhlu lovavanyo kufuneka ibe yinxalenye yesixhobo sovavanyo, esifana nokubhaqwa kwe-AOI.
