What is nanoparticle coating?

Nanoparticle deposition refers to the process of attaching nanoparticles to solid surfaces called substrates to create coatings of nanoparticles. The coatings can have a monolayer or a multilayer and organized or unorganized structure based on the coating method used.

What are polymer nanoparticles?

Polymeric nanoparticles (NPs) are particles within the size range from 1 to 1000 nm and can be loaded with active compounds entrapped within or surface-adsorbed onto the polymeric core. Polymeric NPs have shown great potential for targeted delivery of drugs for the treatment of several diseases.

What is spray coating method?

Spray coating is a technique in which the printing ink is forced through a nozzle whereby a fine aerosol will be formed [25]. In a spray coating process, characteristic performance of polymer solar cells is limited by some drawbacks such as isolated droplets, non-uniform surface and pinholes [10], [47].

How do you rinse nanoparticles?

Centrifuge nanoparticle at high speed ( approximately 6500 rpm for 5-10 minutes) then, wash your nanoparticles with water/ethanol (1:1 v/v) three times and then redisperse nanoparticles in hexane/ water depending upon its nature.

What are polymer nanoparticles used for?

2.2. Polymeric nanoparticles are used for different formulations of drugs by using one these methods, including, adsorption, dissolution, entrapment, encapsulation, or chemical binding of drug molecules on the surface of polymeric nanoparticles (Bhowmik et al., 2015).

Which natural polymer is used in nanoparticles?

29.4. 1 Polymeric Nanoparticles. PNPs are usually made of either natural polymers (chitosan, albumin, and heparin) or synthetic polymers [(N-(2-hydroxypropyl)-methacrylamide, copolymer, poly(ethylene glycol) (PEG), poly(lactic acid–glycolic acid), and poly(lactic acid) (PLA)] for various biomedical applications.

What is metal spray coating?

Metal spraying is a process for covering a surface with a metallic coating using a spray of molten particles. Numerous variations of the technique exist, including: Flame spraying. Wire arc spraying. Plasma spraying.

What is the most commonly used form of thermal spraying?

Thermal spraying processes are usually distinguished by the heat sources used. The most widely used techniques are conventional combustion spraying, high velocity oxy-fuel spraying, wire arc spraying and plasma spraying.
