Aggregation assisted enhancement of singlet oxygen generation by 4-ethynylphenyl substituted porphyrin photosensitizer for photodynamic therapy.

Modulating the photophysical properties of photosensitizers is an effective approach to enhance singlet oxygen generation for photodynamic therapy. Porphyrins are the most widely used photosensitizers due to their biocompatible nature. Aggregation-induced emission (AIE) characteristics of photosensitizers are one of the advantageous features that will enhance fluorescence, intersystem crossing, and efficient triplet state generation.

Exopolysaccharide Produced by Probiotic DM-15 Isolated From Ayurvedic Fermented : Characterization, Antioxidant, and Anticancer Activities.

An exopolysaccharide (EPS) was purified from the probiotic bacterium DM-15, isolated from the Indian Ayurvedic traditional medicine . Gas chromatography-mass spectrophotometry and nuclear magnetic resonance (NMR) analyses revealed the heteropolymeric nature of the purified EPS with monosaccharide units of glucose, galactose, xylose, and rhamnose. Size-exclusion chromatography had shown the molecular weight of the purified EPS as around 240 kDa.

Effect of film constituents and different processing conditions on the properties of starch based thermoplastic films.

The main aim of this study is to examine the different film preparation methods (Hot air oven method, Microwave oven method, and UV irradiation method) for development of Bio-thermoplastic films from agro waste polysaccharides. The rheological properties were also studied for different combinations of tamarind seed starch (T), okra mucilage polysaccharide (OK), Residual rice bran starch (R) and sugarcane bagasse cellulose (C). Increase in concentration of okra mucilage polysaccharide and sugarcane bagasse cellulose found to highly influence the rheological viscous properties of tamarind starch solution.

Active compound diffusivity of particle size reduced S. aromaticum and C. cassia fused starch edible films and the shelf life of mutton (Capra aegagrus hircus) meat.

In the present study, mathematical models were used to examine the effect of active compound diffusion from edible film (supplemented with S. aromaticum and C. cassia) on the microbial, physical and chemical quality of mutton stored at 4 and 10°C.

Production and characterization of cellulose reinforced starch (CRT) films.

Starch from Tamarind seed is considered to be a nonedible and inexpensive component, with many industrial applications. Extraction and characterization of tamarind seed starch was carried out for the synthesis of biopolymer. Tamarind seeds were collected, cleaned and further roasted, decorticated, and pulverized to get starch powder.
