What is nanoparticle functionalization?

Abstract. Functionalization enhances the properties and characteristics of nanoparticles through surface modification, and enables them to play a major role in the field of medicine. Functionalization allows imaging for a prolonged period and enables to track the cells over a period of time.

What are the characteristics of nanoparticles?

There are three major physical properties of nanoparticles, and all are interrelated: (1) they are highly mobile in the free state (e.g., in the absence of some other additional influence, a 10-nm-diameter nanosphere of silica has a sedimentation rate under gravity of 0.01 mm/day in water); (2) they have enormous …

What are the classifications of nanomaterials?

Nanomaterials can be categorized into four types [9, 10] such as: (1) inorganic-based nanomaterials; (2) carbon-based nanomaterials; (3) organic-based nanomaterials; and (4) composite-based nanomaterials. Generally, inorganic-based nanomaterials include different metal and metal oxide nanomaterials.

How does DNA nanotechnology work?

DNA nanotechnology uses artificial nucleic acids as a non-biological engineering material for technological uses. Two-dimensional and three-dimensional crystal lattices, nanotubes, polyhedra and other shapes have all been created, as have functional devices such as molecular machines and DNA computers.

What is the size of nanomaterials?

A nanoparticle is a small particle that ranges between 1 to 100 nanometres in size.

What are the advantages of nanoparticles?

The key advantages of nanoparticles are (1) improved bioavailability by enhancing aqueous solubility, (2) increasing resistance time in the body (increasing half life for clearance/increasing specificity for its cognate receptors and (3) targeting drug to specific location in the body (its site of action).

What are the main classification of nanomedicine?

Nanomaterials can be applied in nanomedicine for medical purposes in three different areas: diagnosis (nanodiagnosis), controlled drug delivery (nanotherapy), and regenerative medicine.
