Fluorescent core–shell silica nanoparticles: towards
Lab on a Particle
architectures for nanobiotechnologyAndrew Burns, Hooisweng Ow and Ulrich Wiesner
Novel nanoscale fluorescent materials are integral to the progress of emergent fields such as nanobiotechnology and facilitate new research in a variety of contexts. Sol–gel derived silica is an excellent host material for creating fluorescent nanoparticles by the inclusion of covalently-bound organic dyes. Significant enhancements in the brightness and stability of organic dye emission can be achieved for silica-based core–shell nanoparticle architectures at length scales down to tens of nanometers with narrow size distributions. This tutorial review will highlight these findings and describe the evolution of the fluorescent core–shell silica nanoparticle concept towards integration of multiple functionalities including mesoporosity, metal nanoshells and quantitative chemical sensing. These developments point towards the development of
lab on a particle
architectures with promising prospects for nanobiotechnology, drug development and beyond.
