Cellulose, the major constituent of all plant materials and the most abundant organic molecule on the Earth, is a linear biopolymer of glucose molecules, connected by β-1,4-glycosidic bonds. Enzymatic hydrolysis of cellulose requires mixtures of hydrolytic enzymes including endoglucanases, exoglucanases (cellobiohydrolases), and β-glucosidases acting in a synergistic manner. In biopolymer hydro...

The progress in the development of DPI technology has boosted the use of sensitive drug molecules for lung diseases. However, delivery of these molecules from conventional DPI to the active site still poses a challenge with respect to deposition efficiency in the lung. At same time, serious systemic side effects of drugs have become a cause for concern. The developed budesonide loaded biopolyme...

Monitoring enzyme secretion in tissue culture has proved challenging because to date the activity cannot be continuously measured in situ. In this Letter, we present a solution using biopolymer loaded photonic crystals of anodized silicon. Shifts in the optical response by proteolytic degradation of the biopolymer provide label-free sensing with unprecedented low detection limits (1 pg) and cal...

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...

Surfactant-based nanostructures are promising materials for designing novel colorimetric biosensors based on aggregation/disaggregation phenomena. In this work, a sensor the plasmonic shift of surfactant-capped gold nanoparticles via disaggregation mechanism was developed. To perform this, optimum SDS concentration firstly determined in order to form Au@16-s-16/SDS complex aggregates with well-...

Soil improvement using biopolymers has attracted considerable attention in recent years, with the aim to reduce harmful environmental effects of traditional materials, such as cement. This paper aims provide a review on assessment binders soil improvement, biopolymer-treated characteristics, well most important factors affecting behavior treated soil. In more detail, benefits and concerns about...

MOTIVATION Most existing bioinformatics methods are limited to making point estimates of one variable, e.g. the optimal alignment, with fixed input values for all other variables, e.g. gap penalties and scoring matrices. While the requirement to specify parameters remains one of the more vexing issues in bioinformatics, it is a reflection of a larger issue: the need to broaden the view on stati...

Following recent x-ray diffraction experiments by Wong, Li, and Safinya on biopolymer gels, we apply Onsager excluded volume theory to a nematic mixture of rigid rods and strong " pi/2" cross-linkers obtaining a long-ranged, highly anisotropic depletion attraction between the linkers. This attraction leads to breakdown of the percolation theory for this class of gels, to breakdown of Onsager's ...

DIFFUSION OF NANOPARTICLES IN SYNTHETIC AND BIOPOLYMERSOLUTIONSbyINDERMEET KOHLIAUGUST 2013 Advisor: Dr. Ashis Mukhopadhyay

The present work was undertaken to evaluate the feasibility of nickel (II) removal from aqueous solution by adsorption onto a biopolymer adsorbent. The adsorbent was prepared using modification of mesoporous silicate SBA-15 with alginate biopolymer (alginateSBA-15) by encapsulation method. Morphological structure of the obtained nanocomposite adsorbent was characterized by XRD, scanning electro...
