Rapid Fluorescence Quenching Detection of Using Natural Silica-Based Nanoparticles.

The development of fluorescent silica nanoparticles (SNP-RB) from natural amorphous silica and its performance as an () biosensor is described in this paper. SNP-RB was derived from silica recovered from geothermal installation precipitation and modified with the dye, Rhodamine B. The Fourier Infrared (FTIR) confirms the incorporation of Rhodamine B in the silica matrix.
