Impact of Magnetic Nanomaterials on Biotechnology and Biomedicine by RV Mehta in Modern Applications of Bioequivalence & Bioavailability | Juniper Publishers

This note describes certain salient features of magnetic nanoparticles and their applications in biotechnology and biomedicine. Twenty first century is said to be the century of nanomaterials and nanotechnology. The word nano is derived from Greek word ‘nano’ means ‘dwarf’. It is one billionth of 1 meter. A page of this journal is about 100,000 nanometers thick. Atomic diameter of gold is nearly one third of a nanometer. So a gold nanoparticle will have only 3-4 atoms .Like this any material at Nanoscale will have only few atoms. In larger particles there are very large numbers of atoms and application of quantum mechanics in multi body is extremely difficult, time consuming and results of classical mechanics and that derived from quantum mechanics are not significantly different. While at Nanoscale situation is different. Only few atoms are there and larger number resides on the surface of the particles as surface to volume ratio is high. Hence, quantum mechanics prevails at this scale.
