Research Perspectives on Functional Micro and Nano Scale Coatings

Abstract

Research topics related to the production of nanocomposites are the most important directions of development of new semiconductor engineering, ensuring high nanocomposites obtaining useful properties in the scope of biophysical characteristics, biomedical and piezoelectric applications. We present two case studies as Hydroxyapatite are in medical applications and aluminum nitride as acoustic wave sensor. Hydroxyapatite, is the main inorganic structure of the tooth enamel and bone and is a biomaterial that is commonly used in biomedical applications that involve bone substitution, drug delivery and bone regeneration because of its excellent biocompatibility, high bioactivity and good osseoconductivity. Since the past decade. Aluminum nitride (AlN), an electrical insulating ceramic with a wide band gap of 6.3 eV, is a potentially useful dielectric material very important in fields such as optoelectronic and micro electronics.

Smart Antibacterial Surface Made by Photopolymerization

“…The adhesion of bacteria to material surfaces (ensuing formation of biofilms) and the associated risk of biofouling is considered to contribute to be a variety of threats, including but not limited to public health, water purification, medical implants, textiles, biosensors, as well as in food packaging and food storage. − Thus, the development of methods to prevent biocontamination on material surfaces have attracted much public attention over the past few decades. There are two different general approaches that have been adopted to avoid biofouling.…”
