I nga tau kua pahure ake nei, ko te huihuinga nanoparticles koura o te DNA i waenga i te rangahau rangahau nui, ko te alkane thiol i whakarereke i nga oligonucleotides me te hononga kovalent koura nanometer, te ahua me te kaupapa polynucleotide raupapa rangahau hybridization, kua whakaemihia nga nanoparticles koura ki roto i te hanganga supramolecular, ko te tukanga whakaemi he whero ki te puru, te huringa tae o te hua ahu tikanga hou colorimetry ki te kitea backlog DNA sequence.Ko te tikanga he tiketike whiriwhiri me te tairongo pai, a ka taea te whakamahi i roto i te ranu ira, rapunga maramara me etahi atu mara.

Ko te punaha marara i hangaia e nga nanoparticles koura i roto i te wai e mohiotia ana ko te koura colloidal.

Ko nga matūriki koura ka taea te herea ki te roopu amino na roto i te whakaurunga electrostatic kore-covalent, te hanga i te here covalent AU-S kaha me te roopu sulfhydryl, ka taea te whakakotahi i te koura colloidal me nga ngota ngota koiora, a ka taea e te rangahau te hanga. whakamahia ki te kimi i te punaha koiora.

Immunogold me immunogold staining hiriwa ma te whakamahi i te koura colloidal hei tohu ka taea te whakamahi mo te tapanga kotahi, maha ranei, a ka taea te whakamahi mo te kounga, localization me te ako ine ine o macromolecules, kua whakamahia whānuitia i roto i te maha o nga mara o te rongoa me te koiora.

Guangzhou Hongwu Material Technology Co., kei te tuku ltd 99.99% au marara koura colloidal, rahi 20nm, 100ppm-10000ppm.

Ko ia ota ka mahia e matou e whakaatu ana i te manaakitanga me te kounga i noho hei kohatu kokonga o to maatau tipu haere tonu.
