Fluorescent Silica Nanobeads

luorescent nanobeads offer great potential for many applications in both basic and applied research. In the recent past, scientists have been offered a wide range of technical solutions in fluorescence imaging, enabling a significant advancement in fields such as microscopy and diagnostics. However, such optical labels mostly spanned the microscale range and/or suffered from limited optical performance and versatility. Recently, the progress of nanoscience has enabled the fabrication of accurately controlled nanostructures with tailored optical properties, and this is disclosing completely unexplored avenues and exciting possibilities in many research areas.
