I tausaga talu ai nei, o le faʻapotopotoga nanoparticles auro o DNA faʻasalalau suʻesuʻega lautele gauai atu, alkane thiol suia oligonucleotides ma nanometer auro covalent fusipaʻu, foliga ma faamoemoega polynucleotide faasologa suʻesuʻe hybridization, reversible nanoparticles auro na potopoto i le fausaga supramolecular, faagasologa accumulation e mumu i le lanumoana, le suiga lanu o le taunuuga e maua mai colorimetry auala fou e iloa backlog DNA sequence.O le auala e maualuga selectivity ma lagona lelei, ma e mafai ona faaaoga i togitogiga hybridization, vaʻavaʻa iloa ma isi fanua.

O le faʻasalalauga faʻapipiʻi e faia e nanoparticles auro i le vai e masani ona taʻua o auro colloidal.

O vaega auro e mafai ona faʻamausaliina ma le vaega amino e ala i le non-covalent electrostatic adsorption, e fausia ai se malosi AU-S covalent bond ma le sulfhydryl group, lea e mafai ai ona tuʻufaʻatasia le auro colloidal ma molekiola bioactive, ma o le suʻega e mafai ona faia. fa'aaogaina i le su'esu'eina o le tino ola.

Immunogold ma immunogold siliva staining e faaaoga colloidal auro e pei o se faailoga e mafai ona faaaoga mo le igoa tasi pe tele, ma e mafai ona faaaoga mo qualitative, localization ma e oo lava suʻesuʻega quantitative o macromolecules, lea ua faaaogaina lautele i le tele o vaega o vailaau ma biology.

Guangzhou Hongwu Material Technology Co., ltd o loʻo tuʻuina atu 99.99% au faʻasalalau auro colloidal, lapoa 20nm, 100ppm-10000ppm.

O fa'atonuga uma matou te fa'atinoina e atagia mai ai le tausiga ma le tulaga lelei sa avea ma maatulimanu o lo matou fa'aauauina pea.
