金纳米粒子 PEG 5000 生物素终止。 应用 金纳米颗粒（直径5 nm，生物素封端，PEG 5000包被，OD 50，在H2O中分散）可用作治疗剂，有望用于癌症治疗和COVID-19的治疗。它也可以用于生物传感应用中的病原体检测。AuNP可用于制备SARS-CoV-2偶联物，用于通过侧向流免疫分析（lateral flow immunoassay ）技术进行COVID-19检测。生物素功能化的金纳米颗粒适用于链霉亲和素标记结合物的结合。金纳米颗粒标记通过测定结合后样品吸光度的增加，可直接检测链霉亲和素。最大吸收与金纳米颗粒大小有关，范围从 515-520 nm（5 nm 颗粒）至 572 nm（100 nm 颗粒）。 Gold nanoparticles PEG 5000 biotin terminated.Biotin functionalized gold nanoparticles are suitable for binding of streptavidin labelled conjugates. The gold nanoparticle label allows for straightforward detection of streptavidin by measuring the increase in absorbance of the sample upon binding. The absorption maximum is gold nanoparticle size dependent, and ranges from 515-520 nm for a 5 nm particle to 572 nm for a 100 nm particle.Gold nanoparticles 5 nm diameter, biotin terminated, PEG 5000 coated, OD 50, dispersion in H2O can be used as a theranostic agent for potential usage in cancer therapy and treatment of COVID-19. It can also be used in the detection of pathogens for biosensing applications. AuNPs may be used to prepare SARS-CoV-2 conjugate for COVID-19 detection using lateral flow immunoassay technique.
