In recent years, the synthetic polymer polyetheretherketone (PEEK) has increasingly been used in a number of orthopedic implementations, due to its excellent mechanical properties, bioinertness, and chemical resistance. For in vivo applications, the surface of PEEK, which does not naturally support cell adhesion, has to be modified to improve tissue integration. In the present work we demonstra...

Since last three decades delivery of the desired drug as muocoadhesive drug delivery systems has been subject of interest. Mucoadhesion involving a polymeric drug delivery system is a complex phenomenon that includes theory of diffusion, wetting, adsorption, fracture and interpenetration of polymer chains amongst various other processes. Various polymer-based properties such as the degree of cr...

We present a simple yet robust method for fabricating angled, hierarchically patterned high-aspect-ratio polymer nanohairs to generate directionally sensitive dry adhesives. The slanted polymeric nanostructures were molded from an etched polySi substrate containing slanted nanoholes. An angled etching technique was developed to fabricate slanted nanoholes with flat tips by inserting an etch-sto...

Today, packaging plays a crucial role in maintaining the quality of products during uses by providing safeguarding against physical, chemical and environmental challenges. While polymer-based material has been very extensively used, there recent move to paper-based because their economic environmentally-friendly nature. Currently, Paper board materials have used as for food products, e-commerce...

The utilization of used polystyrene as adhesive material for emulsion polymer asphalt has been carried out. Polystyrene foam was dissolved in toluene at the ratio 30:70 mL, then solution mixed with aquadest ratios 90: 10 70: 30 50: 50 and 10: 90 mL. Then added mL Sodium Dodecyl Sulfate concentrations 10%, 20%, 30%. most stable latex 200 g sand aggregate volume 20 40 mixture pressed into a hotpr...

BACKGROUND Secondary caries are considered the main cause of dental restoration failure. In this context, anti-biofilm and bactericidal properties are desired in dental materials against pathogens such as Streptococcus mutans. To this purpose, graphene based materials can be used as fillers of polymer dental adhesives. In this work, we investigated the possibility to use as filler of dental adh...

Single Cell Force Spectroscopy was combined with Electrochemical-AFM to quantify the adhesion between live single cells and conducting polymers whilst simultaneously applying a voltage to electrically switch the polymer from oxidized to reduced states. The cell-conducting polymer adhesion represents the non-specific interaction between cell surface glycocalyx molecules and polymer groups such a...
