Applications of diatoms and silica nanotechnology in biosensing, drug and gene delivery, and formation of complex metal nanostructures

2011

Abstract Diatoms, single-cell eukaryotic microalgae, are present in nearly every water habitat and their silicon-dioxide (silica)-based cell walls of tens to hundreds of micrometers in size are the most interesting feature to be used in nanotechnology, including biosensing, drug delivery, molecular separation, molecular biology, biomimetics, frustule formation, and electronic, photonic, optical and structural materials. In this review, we present recent progress in applications of diatoms and silica nanomaterials in biosensing, drug and gene delivery, and formation of complex metal nanostructures.
