Development of Soft-Matter Delivery Systems: Coupling pH Responsive Polymers to Porous Silica Particles
<p>This work investigates polymeric coating of evaporated induced self-assembly (EISA) mesoprous silica nanoparticles for potential use in controlled drug release and therapeutics. As demonstrated here, lipid bilayer coatings can be easily replaced with different polymer analogs allowing for …

The effect of molecular weight on the behavior of polystyrene coated steel disks under fretting conditions
Thin polymeric coatings have been applied to metal surfaces to prevent and/or prolong the onset of fretting corrosion, but the properties that make a polymeric coating effective and the means by which a coating fails are unknown. The purpose of this study was to determine the effect of molecular …

Magnetic targeted drug delivery system in gene therapy
… and summarizes the research process of polymeric coating as a function of gene vectors. Nuclear magnetic resonance technology is used to identify the structure of the polymer step by step. At last, the use of PLLA(poly(L lactic acid)) in gene therapy is combined with the MTDDS. The …

Quantitative evaluation of thin film adhesion using the probe test
… the adhesion in thin adhesive films and coatings. The technique was initially developed as a qualitative test by the Hewlett-Packard Company for measuring adhesion of thin film microelectronic coatings. In the probe test method, an inclined needle-like probe with a conical tip is advanced …

Tribology of polymeric coatings for aggressive bearing applications
… to implement some type of advanced protective coatings on the interacting surfaces to withstand stringent contact conditions. Due to favorable tribological performance, polytetrafluoroethylene (PTFE)- and polyetheretherketone (PEEK)-based polymeric coatings have received interest in ACR …

Evaluation of the critical parameters and polymeric coat performance in compressed multiparticulate systems
… and rheological analysis techniques. Different coating formulations were made of ethyl cellulose (EC) as a coating polymer and two different kinds of additives were incorporated into the polymeric coating solution. Triethyl Citrate (TEC) and Polyethylene glycol 400(PEG400) were used as …

Mathematical modeling and simulation of intravascular drug delivery from drug-eluting stents with biodegradable PLGA coating
… A DES elutes drug compounds from a thin polymeric coating into the surrounding coronary artery tissue to reduce in-stent restenosis (a significant lumen loss due to growth of vascular tissue). Biodurable (non-erodible) polymers are often used in the current DES coatings, which stay …
