Molecular Surface Engineering of Bio-Compatible Coatings

Jeff Chinn, , Integrated Surface Technologies

Surface engineering techniques through to use of specialized molecular chemistries can be used to develop or mitigate a wide range of functional properties, including physical, chemical, fluid flow, electrical, and corrosion-resistant properties. Almost all types of materials including metals, semiconductors, ceramics, polymers, and composites can be coated with molecular films to alter their surface states. Common surface engineered properties of interest often include: control of surface energies (hydrophobicity, hydrophilicity, anti-fouling), chemical grafting (functional groups –NH2, -OH, -COOH, -SH2, etc.), molecular level cleaning, surface activation, adhesion promotions (chemical activation for bonding, immobilizing DNA) and preservation (corrosion inhibitors, moisture barriers). These nano-scaled films can be engineered into many unique bio-compatible coatings. In this talk, we will review the basics of molecular coatings that are commonly used and a technique to applied and to control of surface properties for applications like micro-fluidics, genomics, PCR and others.
