Colloidal kub

Colloidal kub nanoparticlestau siv los ntawm cov kws ua yeeb yam rau ntau pua xyoo vim lawv cuam tshuam nrog lub teeb pom kev los tsim cov xim ci.Tsis ntev los no, cov cuab yeej photoelectric tshwj xeeb no tau tshawb fawb thiab siv rau hauv high-tech fields xws li cov organic solar cells, sensor probes, therapeutic agents, drug delivery systems in biological and medical applications, electronic conductors, and catalysis.Cov khoom siv kho qhov muag thiab hluav taws xob ntawm kub nanoparticles tuaj yeem hloov kho los ntawm kev hloov lawv qhov loj, zoo li, nto chemistry thiab aggregation xeev.

Cov tshuaj colloidal kub yog hais txog ib tug kub sol nrog ib tug dispersed theem particle txoj kab uas hla ntawm 1 thiab 150 nm.Nws belongs rau heterogeneous heterogeneous system, thiab xim yog txiv kab ntxwv mus rau ntshav.Kev siv cov colloidal kub ua tus cim rau immunohistochemistry pib hauv 1971. Faulk li al.Siv electron microscopy immunocolloidal kub staining (IGS) los soj ntsuam Salmonella.

Sau npe rau ntawm cov tshuaj tiv thaiv thib ob (nees anti-tib neeg IgG), ib qho kev tsis ncaj ncees ntawm cov tshuaj tiv thaiv kab mob kub hnyiab tau tsim.Xyoo 1978, geoghega tau tshawb pom daim ntawv thov ntawm cov cim kub colloidal ntawm lub teeb tsom iav.Daim ntawv thov ntawm colloidal kub hauv immunochemistry kuj hu ua immunogold.Tom qab ntawd, ntau tus kws tshawb fawb tau lees paub ntxiv tias cov kub colloidal tuaj yeem nqus cov protein kom ruaj khov thiab nrawm, thiab kev ua haujlwm lom neeg ntawm cov protein tsis tau hloov pauv ntau.Nws tuaj yeem siv los ua kev sojntsuam rau qhov tseeb ntawm qhov chaw ntawm tes ntawm tes thiab intracellular polysaccharides, proteins, polypeptides, antigens, cov tshuaj hormones, nucleic acids thiab lwm yam macromolecules lom.Nws kuj tseem tuaj yeem siv rau kev tiv thaiv kab mob txhua hnub thiab immunohistochemical hauv zos, yog li hauv kev kuaj mob thiab kev siv tshuaj tshawb nrhiav thiab lwm yam muaj txiaj ntsig zoo.Tam sim no, immunogold staining ntawm qib electron microscope (IGS), immunogold staining ntawm lub teeb tsom iav theem (IGSS), thiab speckle immunogold staining ntawm qib macroscopic tau nce los ua cov cuab yeej muaj zog rau kev tshawb fawb thiab kev kuaj mob.
