nanoparticles for biological solutions

Welcome to the Nano Biosols gold-blog: a potted history of the technology


Welcome to the Nano Biosols gold-blog.  Nano Biosols is a new start up supplying gold nanoparticles to industry and  the bio-medical research community with a view to developing the technology in the future.  In the 1970’s  we were introduced to the concept of immunogold. The only application was in immonoelectron microscopy where particles were visualised as  black dots where they bound on biological samples. Through innovative steps the particles were also used in light microscopy and protein blotting techniques  in combination with silver enhancement techniques. The second generation of gold based reagents were developed to be used  in lateral flow in-vitro diagnostic assays due to their macroscopic ruby red colour. It was around the new millennium in 2000 that the term nanoparticle appeared in relation to gold and the concept of the third major application surfaced in the form of therapeutics. The concept of nanomedicine , i.e. use of nanomaterials as therapeutic agents in medicine had developed. It is expected that these theranostics will have multi-modal properties of targeting, imaging and delivering a therapeutic effect. The future looks bright for the continuous development of applications of gold nanoparticles  even in other non biological sectors such as catalysis and solar energy. Who knows where the next  innovative application of these versatile materials will take us ? I hope this blog can be a sounding board for new ideas, applications and problem solving in the nano gold community.
