Li-probe tsa liteko ke likhechana tse nyane tsa DNA kapa RNA (hoo e ka bang 20 ho isa ho 500 bp) tse sebelisetsoang ho bona tatellano ea li-nucleic acid.DNA e nang le likhoele tse peli e fetoloa ka ho futhumatsa hore e be stranded e le 'ngoe, ebe e ngotsoe ka radioisotopes (hangata phosphorus-32), li-fluorescent dyes, kapa li-enzyme (tse kang horseradish peroxidase) hore e be li-probes.Phosphorus-32 hangata e kenyelelitsoe sehlopheng sa phosphate sa e 'ngoe ea li-nucleotide tse' nè tse etsang DNA, 'me li-fluorescent dyes le li-enzyme li hokahanngoa ka mokhoa o kopanetsoeng le tatelano ea nucleic acid.
Hona joale setsing sa teko, probe ea teko e sebelisoa e le seaplane, probe e behoa ka har'a casing, hlooho ea probe e hokahana le ntho e lokelang ho lekoa, 'me terata e etellang pele ea casing pheletsong e 'ngoe e tsamaisa lets'oao, mme lets'oao le amohetsoeng le ka har'a mohlahlobi.Ka mohlala, mohanyetsi o sebelisa mohloli oa hona joale ho bala ho theoha ha motlakase ho pholletsa le probe, 'me capacitor e sebelisa mohloli oa motlakase o sa khaotseng ho bala moepa oa nako ea ho tjhaja ka maqhubu a fapaneng.Probe e na le litšoaneleho tsa tšebeliso e tsoelang pele ha e etsoa sesebelisoa, 'me litšenyehelo ha li phahame.O sebelisitsoe haholo sechabeng sa liteko.
Ho na le mefuta e mengata ea mefuta ea li-probe tsa liteko.Lebaka le ka sehloohong ke hore lintlha tse fapaneng tsa teko li hloka mefuta e fapaneng ea hlooho.Mohlala, maoto a dip a sebelisa mefuta ea lihlooho tse nang le manala a mangata, lintlha tsa pampiri ea teko li sebelisa lihlooho tse nchocho, tse chitja kapa tse bataletseng, 'me IC pins e sebelisa plum blossom.Sebopeho sa hlooho, joalo-joalo kaofela li khethoa ke basebetsi ba nang le phihlelo ba tlhahiso ho latela likarolo tsa PCB e phethiloeng.
Nanometering ke feela ho matlafatsa lisebelisoa bakeng sa probe, 'me ha ho na tšusumetso ho sebopeho sa liteko.Haeba o na le thahasello, litlamorao ho sesebelisoa sa tlhahlobo e lokela ho ba karolo ea sesebelisoa sa tlhahlobo, joalo ka ho lemoha AOI.
