Dahab ka samaysan

Nanoparticles dahab ah kolloidalwaxaa isticmaali jiray fanaaniinta qarniyo badan sababtoo ah waxay la falgalaan iftiinka muuqda si ay u soo saaraan midabyo dhalaalaya.Dhowaan, hantidan gaarka ah ee korantada ayaa la baadhay oo lagu dabaqay qaybaha farsamada sare sida unugyada cadceedda dabiiciga ah, baaritaanka dareemayaasha, wakiilada daweynta, hababka gudbinta daroogada ee codsiyada bayoolojiga iyo caafimaadka, kiriyeyaasha elektaroonigga ah, iyo catalysis.Qalabka indhaha iyo elektiroonigga ah ee nanoparticles dahabka ah waxaa lagu hagaajin karaa iyada oo la beddelo cabbirkooda, qaabkooda, kimistariga dusha sare iyo xaaladda isku-darka.

Xalka dahabka kolloidhka waxa loola jeedaa sol dahab ah oo leh dhexroor qaybeed kala firdhiyey inta u dhaxaysa 1 iyo 150 nm.Waxay ka tirsan tahay nidaamka heterogeneous heterogeneous, midabkuna waa orange ilaa guduud.Isticmaalka dahabka kolloidal sida calaamadaynta immunohistochemistry wuxuu bilaabmay 1971. Faulk et al.La isticmaalay mikroskoob elektaroonig ah midabaynta dahabka ee immunocolloidal (IGS) si loo eego Salmonella.

Lagu calaamadiyay antibody-ka labaad (faras ka-hortagga bini'aadamka IgG), qaab dahab ah oo aan toos ahayn oo difaaca jirka ah ayaa la sameeyay.Sannadkii 1978-kii, geoghega waxa uu daah-furay adeegsiga calamadaha dahabka kolloidhka ah ee heerka muraayadda iftiinka.Codsiga dahabka kolloidal ee immunochemistry waxa kale oo loo yaqaan immunogold.Intaa ka dib, culimo badan ayaa sii xaqiijiyey in dahabka kolloidalku uu si deg deg ah oo degdeg ah u soo saari karo borotiinnada, iyo dhaqdhaqaaqa nafleyda ee borotiinku si weyn isuma beddelin.Waxaa loo isticmaali karaa sidii baaritaan loogu talagalay meelaynta saxda ah ee dusha unugyada iyo polysaccharides intracellular, borotiinada, polypeptides, antigens, hormoonnada, acids nucleic iyo macromolecules kale oo bayooloji ah.Waxa kale oo loo isticmaali karaa ogaanshaha maalinlaha ah ee immunodiagnosis iyo immunohistochemical localization, sidaas darteed ogaanshaha kiliinikada Iyo codsiga ogaanshaha daroogada iyo dhinacyo kale ayaa si weyn loo qiimeeyay.Waqtigan xaadirka ah, midabaynta difaaca jirka ee heerka mikroskoob ee elektarooniga ah (IGS), midabaynta difaaca jirka ee heerka mikroskoob ee iftiinka (IGSS), iyo midabaynta speckle immunogold ee heerka makroscopic ayaa sii kordheysa inay noqdaan aalado awood leh oo loogu talagalay cilmi-baarista sayniska iyo ogaanshaha caafimaad.
