The advancement of clinical medicine established exceptionally in today’s era is used to cure many infectious diseases. Unfortunately, the negative aftermath associated with synthetic drugs has caused turn their attention towards an alternative, which natural plant-extract drugs. Plant-based have a vast number benefits and applications biomedical field are further formulated nanocomposite hydro...

Nanofibrous scaffolds are of interest in tissue engineering due to their high surface area to volume ratio, interconnected pores, and architectural similarity to the native extracellular matrix. Our laboratory recently developed a biodegradable, photo-crosslinkable alginate biopolymer. Here, we show the capacity of the material to be electrospun into a nanofibrous matrix, and the ability to enh...

Alginate production by the highly alginate-producing Pseudomonas aeruginosa 8821M was maximal at a dissolved oxygen tension (DOT) of 5% of air saturation. Lower DOT limited growth and alginate synthesis. At higher DOT values up to 70% of air saturation, the specific alginate production rate decreased. Nevertheless, the molecular mass of the alginate increased at higher aerations, as indicated b...

Delivery systems based on filled hydrogel particles (microgels) can be fabricated from natural food-grade lipids and biopolymers. The potential for controlling release characteristics by modulating the electrostatic interactions between emulsifier-coated lipid droplets and the biopolymer matrix within hydrogel particles was investigated. A multistage procedure was used to fabricate calcium algi...

Novel Pickering emulsions were stabilized by complex interfaces in the presence of zein colloidal particles (ZCPs), propylene glycol alginate (PGA), and rhamnolipid (Rha) for delivery ?-carotene. The influence particle-surfactant, particle-biopolymer, particle-biopolymer-surfactant mixed on physiochemical properties digestion fate was investigated. It is first time that three different types em...

Taesik Chae, Heejae Yang, Frank Ko, Tom Troczynski. Materials Engineering Department, University of British Columbia, Vancouver, BC Canada V6T 1Z4 Statement of Purpose: Aging of population increases the need for human organ/tissue repairs. Autografts supply, however, has limitation, and allografts may cause the risk of disease transmission and anti-immunization response. One of the alternatives...

Clay-Based Robust Hemostats In article 2202265 by Mingxian Liu, Yuri Lvov, and co-workers, an efficient clay hemostat of halloysite nanotubes is tightly assembled onto cotton fibers capillaries mediated a biopolymer alginate with Ca2+ crosslinking. This dressing maintains high clotting activity after washing only few residuals in the wound. strategy balances robustness, biosafety, effectiveness...

Transparent aerogels of biopolymer–polysiloxane double networks have been developed. In their Research Article (e202306518), Satoru Takeshita and Takumi Ono established a sequential protocol for condensation methyltrimethoxysilane crosslinking various biopolymers such as alginate, carrageenan, pectin, carboxymethyl cellulose in the same space. The drawbacks or polysiloxane alone can be overcome...

Abstract Grafting of styrene (S) onto biopolymer Sodium Alginate (NaAlg) via free-radical polymerization forming (NaAlg-g-PS), using potassium persulfate K 2 S O 8 (KPS) as initiator. Fourier-transform infrared spectroscopy (FT-IR) and Proton nuclear magnetic resonance ( 1 H-NMR) characterized the formed grafted copolymer scanning electron microscope (SEM) to show changes in surface morphology ...
