- Abstract:
- ... The growing dye pollution has become an urgent threat to environmental and biological safety. To meet the requirements of both dye adsorption and photocatalytic degradation in complicated wastewater environments, here, a novel La(OH)₃-immobilized alginate/polyacrylamide composite hydrogel (La(OH)₃@SA/PAM) is fabricated by in situ growth of La(OH)₃ on the inner walls of alginate/polyacrylamide netw ...

- Abstract:
- ... Surface tension driven assembly is a simple and rapid strategy in “modular” tissue engineering to fabricate three-dimensional (3D) structures with predefined geometrical and biological features. Besides the biocompatibility for encapsulated cells, the mechanical and hydrophilic properties of the microgel are the utmost two factors for assembly and structure preservation. Herein, we developed a new ...

Our study reports a versatile immobilization method of Hemagglutinating Virus of Japan Envelope (HVJ-E) for the generation of viral-mimetic surfaces for hormone resistant prostate cancer cell isolation. HVJ-E has recently attracted much attention as a new type of therapeutic material because hormone resistant prostate cancer cells such as PC-3 cells possess the HVJ-E receptors, GD1a. The HVJ-E was ...

- Abstract:
- ... As vectors of pathogens, ticks pose a considerable problem in most parts of the world. Most tick bites in Germany are caused by Ixodes ricinus for which there is no specific scientifically proven control agent available. Although biological control options like entomopathogenic fungi are known, there is a lack of studies on formulation and applicability. This study presents a broad biotechnologica ...

A perfect wound covering should prevent dryness of the wound and provide a favourable moist milieu at the wound interface allowing gas access but act as a barrier to the dirt and microorganisms. It is imperative to ensure early restoration of wound without scar formation at the site. Topical application of antiseptic preparation is the best for wound treatment because of its direct action.
