Colloidal Kub

Colloidal Kub Nanoparticlestau siv los ntawm cov kws kos duab rau ntau pua xyoo vim tias lawv sib cuam tshuam nrog pom lub teeb kom ua cov xim ci. Tsis ntev los no, qhov cim duab photicelecric no tau tshawb fawb thiab thov cov phiaj xwm kev siv hluav taws xob, kev siv tshuaj yeeb yaj kiab thiab cov ntawv thov kev kho mob, cov khoom siv hluav taws xob, thiab catalysis. Cov khoom siv kho tshiab thiab hluav taws xob ntawm kub nanoparticles tuaj yeem hloov kho los ntawm kev hloov pauv lawv qhov loj me, kev siv tshuaj thiab kev sib sau ua ke hauv lub xeev.

Lub colloidal kub kev daws yog hais txog ib tus kub kub nrog lub sij hawm dispersed dispersed particle inch ntawm 1 thiab 150 nm. Nws zwm rau cov kab ke heterogeneous heterogeneous, thiab cov xim yog txiv kab ntxwv rau ntshav. Kev siv cov kub colloidal ua tus cim rau immunohistochemtry pib xyoo 1971. Faulk li al. Siv hluav taws xob tsom iav microscktoporoid kub staining (igs) kom soj ntsuam Salmonella.

Sau npe rau ntawm lub antibody thib ob (nees tawm tsam tib neeg IGG), ib txoj kev Immunocolloid kub tau tsim. Xyoo 1978, Geoghega nrhiav tau daim ntawv thov colloidal kub cim ntawm lub teeb tsom iav. Daim ntawv thov ntawm Collroidal Kub hauv Immunochemontry tseem hu ua immunogold. Tom qab, muaj ntau tus kws tshawb fawb ntxiv tias kub colloidal kub tau adsorb protein stably thiab sai sai, thiab kev ua si ntawm cov protein tsis tau hloov pauv ntau. Nws tuaj yeem siv los ua kev sojntsuam rau kev ua kom haum ntawm cov xovtooj ntawm tes thiab antigens, cov tshuaj hormones, nucleic acids thiab lwm yam macromolecules. Nws kuj tseem siv tau rau kev txhaj tshuaj txhua hnub thiab txhaj tshuaj tiv thaiv kab mob thiab kev kuaj mob tshuaj thiab lwm yam tau muaj nuj nqis. Tam sim no, immunogold staining ntawm lub tshuab hluav taws xob qib (iGS), txhaj tshuaj tiv thaiv lub zog rau kev tshawb fawb thiab kuaj mob kev kuaj mob.
