Zoyesa zoyesa ndi tiziduswa tating'ono ta DNA kapena RNA (pafupifupi 20 mpaka 500 bp) zomwe zimagwiritsidwa ntchito pozindikira kutsatizana kwa nucleic acid.DNA yamitundu iwiri imasinthidwa ndi kutenthedwa kuti ikhale yamtundu umodzi, kenako imalembedwa ndi radioisotopes (nthawi zambiri phosphorous-32), utoto wa fulorosenti, kapena ma enzyme (monga horseradish peroxidase) kuti akhale ma probes.Phosphorus-32 nthawi zambiri imaphatikizidwa mu gulu la phosphate la imodzi mwa nucleotide zinayi zomwe zimapanga DNA, ndipo utoto wa fulorosenti ndi ma enzymes amalumikizidwa molumikizana ndi ma nucleic acid sequences.
Tsopano muzoyeserera zoyeserera, kafukufuku woyeserera amagwiritsidwa ntchito ngati sing'anga, kafukufukuyo amayikidwa m'bokosi, mutu wa probe umalumikizana ndi chinthu choti chiyesedwe, ndipo waya wotsogolera wa casing kumapeto kwina umatulutsa chizindikiro, ndipo chizindikiro cholandilidwa chiri mu tester.Mwachitsanzo, wotsutsa amagwiritsa ntchito gwero lamakono kuti awerengere kutsika kwa voteji pa kafukufuku, ndipo capacitor imagwiritsa ntchito gwero lamagetsi nthawi zonse kuti iwerengere kutsetsereka kwa nthawi yolipiritsa pamaulendo osiyanasiyana.Pulogalamuyi ili ndi mawonekedwe ogwiritsidwa ntchito mosalekeza ikapangidwa kukhala chokhazikika, ndipo mtengo wake siwokwera.Wagwiritsidwa ntchito kwambiri m'magulu oyesera.
Pali mitundu yambiri yamitundu yama test probe head.Chifukwa chachikulu ndi chakuti mfundo zoyesa zosiyana zimafuna mitundu yosiyanasiyana yamutu.Mwachitsanzo, kuviika mapazi amagwiritsa ntchito mitundu ya mitu ya zikhadabo zambiri, malo oyesera amagwiritsa ntchito mitu yosongoka, yozungulira kapena yosalala, ndipo ma IC pin amagwiritsa ntchito maluwa.Mutu mawonekedwe, etc. onse amasankhidwa ndi ogwira ntchito odziwa kupanga malinga ndi mbali pa PCB yomalizidwa.
Nanometering ndikungolimbitsa zida za kafukufukuyo, ndipo palibe chokhudza kuyesererako.Ngati mukufuna, kukhudzika kwa choyesacho kuyenera kukhala gawo la chida choyesera, monga kuzindikira kwa AOI.
