The formulation of a novel delivery system for ellagic acid formulated via layer-by-layer (Lb-L) electrostatic deposition of biopolymers onto soybean lecithin liposomes was achieved. Optimization of parameters affecting the formulation of biopolymer-coated liposomes was carried out by monitoring changes on its size, surface charge and morphology. Ellagic acid was loaded into the liposome core a...

Filamentous biopolymer networks in cells and tissues are routinely imaged by confocal microscopy. Image analysis methods enable quantitative study of the properties of these curvilinear networks. However, software tools to quantify the geometry and topology of these often dense 3D networks and to localize network junctions are scarce. To fill this gap, we developed a new software tool called "S...

We report the current–voltage characteristics of gold nanoparticle–biopolymer networks at room temperature. The characteristics have features that are indicative of single-electron charging in ordered, one-dimensional chains of nanoparticles. From capacitance estimates and numerical simulations, we argue that the observed electrical behavior is related to the low size dispersion of the nanopart...

We present a detailed description of biopolymer translocation through a nanopore in the presence of a solvent using an innovative multiscale methodology that treats the biopolymer at the microscopic scale as combined with a self-consistent mesoscopic description for the solvent fluid dynamics. We report evidence for quantized current blockade depending on the folding configuration and offer det...

In this paper an attempt has been made to develop an appropriate storage and collection plan based on optimal routing model using Geologic Information System in one of the wards of the Singanallur, Coimbatore city, India. The ward map is digitized and georeferenced. The collection bins are attributed and collection routes of the MSW are optimized for degradable and recyclable wastes separately....

Considerable efforts have been placed on the development of degradable microspheres for use in transarterial embolization indications. Using the guidance of the U.S. Food and Drug Administration (FDA) special controls document for the preclinical evaluation of vascular embolization devices, this review consolidates all relevant data pertaining to novel degradable microsphere technologies for bl...

A synthetic polymer is a plastic, which having wide applications in our day-to-day life. The packaging industries, agriculture, cosmetics, etc. Plastics are not easily degradable, it takes 1000 years to degrade plastic or even more than that. pollution caused by only because of the waste disposal method but also releases carbon dioxide and dioxins while burning. considered threat environment as...

Recent developments in the synthetic degradable polymers have been the subject of significant interest for macromolecular science to both of an environmental and biomedical perspective with dedication towards applications in tissue engineering and drug delivery. The best candidate for degradable polymer is poly (lactic acid) (PLA), which is described as aliphatic polyester [1]. It is produced f...

We use passive and active techniques to study microrheology of a biopolymer solution. The passive technique is video tracking of tracer particles in the biopolymer, a technique which is well established. The active technique is based on rotating optical tweezers, which is used to study viscosity. A method to actively measure viscoelascity using time varying rotation of a particle trapped in opt...
