In spite of the potential use of nanomaterials as tissue engineering devices, implants, biosensors, drug delivery devices, etc., there has yet to be a compilation of the risks associated with the in vivo use of nanomaterials. There are numerous and well-known risks because of the size of nanoparticles. For example, nanoparticles can cross cell membranes and enter the cytoplasm undetected. The aim of this book is to provide one of the first (if not...
