Polymers stabilize the nanoparticles onto which they wrap, avoiding coagulation and undesired phase separation processes. Wrapping gives rise to hybrid colloids, is useful in bio-intended applications. In non-covalent interaction modes, polymers physically adsorb nanoparticles’ surface, NPs, some of their portions protrude outside. Both non-interacting parts free are contact with solvent, and/o...

The high throughput discovery of new bio materials can be achieved by rapidly screening many different materials synthesised by a combinatorial approach to identify the optimal composition that fulfils a particular biomedical application. Here we review the literature in this area and conclude that for polymers this process is best achieved in a microarray format, which enable thousands of cell...

We recently introduced a series of stimuli-responsive, mechanically adaptive polymer nanocomposites. Here, we report the first application of these bio-inspired materials as substrates for intracortical microelectrodes. Our hypothesis is that the ideal electrode should be initially stiff to facilitate minimal trauma during insertion into the cortex, yet become mechanically compliant to match th...

In the paper will be presented a safety and security system based on fingerprint technology. The results suggest a new scenario where the new cars can use a fingerprint sensor integrated in car handle to allow access and in the dashboard as starter button. Introduction One of the most relevant question in the security world is how identify and recognize people not only in some protected areas w...

This paper reports the rheological behavior of swelled and mineralized hydrogel prepared using polyvinylpyrrolidone (PVP) and carboxymethylcellulose (CMC) hydrogel as base polymer. Herein, the bio-mineral calcium carbonate (CaCO3) was incorporated into the hydrogel using simple liquid diffusion method. The morphology of the swelled and mineralized hydrogel was analyzed through scanning electron...

Fused deposition modeling (FDM), one among the most commonly used additive manufacturing (AM), techniques has been widely in recent years to produce customized parts with intricate geometries, especially from thermoplastics. This method was limited its ability for industrial applications due inferior properties and poor quality of fabricated parts. Hence, researchers are being driven discover n...

Precise knowledge of the mechanical properties of emerging nanomaterials and nanocomposites is crucial to match their performance with suitable applications. While methods to characterize mechanical properties exist, they are limited by instrument sensitivity and sample requirements. For bio-based nanomaterials this challenge is exacerbated by the extreme dependence of mechanical properties on ...

Bio-films have been produced that attract attention with their functional behavior among conventional food packaging materials of bio-based polymer blends. The physical and morphological properties copolymeric biofilms extensively investigated. Biodegradable copolymer films were by in situ polymerization technique prepared as solution casting. strong water absorbency polyvinyl alcohol the antim...
