Although poly(alpha-hydroxy esters), especially the PLGA family of lactic acid/glycolic acid copolymers, have many properties which make them promising materials for tissue engineering, the inherent chemistry of surfaces made from these particular polymers is problematic. In vivo, they promote a strong foreign-body response as a result of nonspecific adsorption and denaturation of serum protein...

In this paper an overview about the applications of Aerogels in the fields of pharmacy, cosmetics, medicine, agriculture and biotechnology is given. The in situ encapsulation of proteins and enzymes into aerogels was shown to be a very promising technique leading to the increase of biocatalytical activity. Furthermore aerogels are used as host matrix for bio-active compounds, which improve or e...

The coating of solid-binding peptides (SBPs) on inorganic material surfaces holds significant potential for improved surface functionalization at nano-bio interfaces. In most related studies, the goal has been to engineer peptides with selective and high binding affinity for a target material. The role of the material substrate itself in modulating the adsorption behavior of a peptide molecule ...

Understanding the adsorption properties of DNA bases on metal surfaces is fundamental for the rational control of surface functionalization leading to the realisation of biocompatible devices for biosensing applications, such as monitoring of particular parameters within bio-organic environments and drug delivery. In this study, the effects of deposition rate and substrate temperature on the ad...

The free growth of ice crystals in supercooled bulk water containing an impurity of glycoprotein, a bio-macromolecule that functions as 'antifreeze' in living organisms in a subzero environment, was observed under microgravity conditions on the International Space Station. We observed the acceleration and oscillation of the normal growth rates as a result of the interfacial adsorption of these ...

Empty Fruit Bunches (EFB) are oil palm waste that has the potential as a source of bioenergy because it contains lignocellulose (cellulose, hemicellulose, and lignin) so can be converted into biofuel through thermal cracking, adsorption, distillation processes. Thermal cracking is decomposition chemical content biomass by utilizing heat without mixture oxygen at temperature 200oC–600oC. This st...

Heavy metals are among the most dangerous substances that cause pollution and accumulation in nature. The bio-sensitive way to decompose these pollutants is through adsorption studies with biopolymers. In this study, chitosan, one of common cost-effective biopolymers, was produced be employed aluminum lead, which have proven negative effects on living organisms. production stages shrimp crab sh...

Hemicelluloses are the earth's second most abundant structural polymers, found in lignocellulosic biomass. Efficient enzymatic depolymerization of xylans by cleaving their β-(1 → 4)-glycosidic bonds to produce soluble sugars is instrumental to the cost-effective production of liquid biofuels. Here we show that the multi-scale two-phase process of enzymatic hydrolysis of amorphous hemicelluloses...

Synthetic polycations show great potential for the construction of ideal non-viral gene delivery systems. Several cationic polymers were synthesized by the epoxide ring-opening polymerization between diepoxide and various polyamines. Disulfide bonds were introduced to afford the polymers bio-reducibility, while the oxygen-rich structure might enhance the serum tolerance and biocompatibility. Th...
