Introduction to Metal Nanoparticles

Metallic nanoparticles are a special class of chemical object that are ubiquitous in many fields of science, such as physics, chemistiy, materials science, biochemistry and nanotechnology. Metallic nanoparticles exhibit many special diverse characteristics such as optical, electronic, magnetic and related properties. Most research attention has been focused on the control of the size and shape of nanoparticles, aiming at their utilization in well-defined chemistiy. 

Quantum dots (QDs), with obvious fluorescence properties, exhibit superior properties to those of traditional dyes, such as strong fluorescence emission intensity, broad excitation, and long fluorescence time. Pillar[5]arenes with carbo ylate groups can be introduced as a stabilizer of QDs to expand their applications. 

Nanoparticles of Fe304 are magnetic and therefore can be used in absorption and extraction via the magnetic response. Pillar[5]arenes hybridized with Fe304 nanoparticles are expected to show special properties and immense application potential.
