Medical Nanomaterials and Nanodevices

One of the simplest medical nanomaterials is a surface perforated with holes, or nanopores. These pores are large enough to allow small molecules such as oxygen, glucose, and insulin to pass but are small enough to impede the passage of much larger immune system molecules such as immunoglobulins and graft-borne virus particles. Hybrid “nanodevice” composed of 4.5-nm nanocrystals of biocompatible titanium dioxide semiconductor covalently attached with snippets of oligonucleotide DNA. Both single-walled and multiwalled carbon nanotubes are also being investigated as biosensors; for example, to detect glucose, ethanol, hydrogen peroxide, selected proteins such as immunoglobulins, and an electrochemical DNA hybridization biosensor.
