Polymeric micelles, which form upon self-assembly of amphiphilic macromolecules, can act as vehicles for the oral delivery of these drugs. This manuscript.This review summarizes recent developments related to targeted anticancer drug delivery to tumor sites using polymeric micelles via active and passive.approach in the field of polymeric drug delivery systems was introduced by the. Functionali...

Drug delivery systems comprising vesicles prepared from one amphiphile encapsulating vesicles prepared from a second amphiphile have not been prepared previously due to a tendency of the bilayer components of the different vesicles to mix during preparation. Recently we have developed polymeric vesicles using the new polymer-palmitoyl glycol chitosan and cholesterol in a 2:1 weight ratio. These...

A novel graphical method of analysing continuous membrane separation systems has been developed. The method is applicable to all counterand co-current membrane modules – single-stage, cascades, and membrane columns. All configurations can be broken down into “column sections”, no matter how complex the arrangement. Each column section, which resembles a typical single-stage separator, is modell...

due to the importance of the plant extracts and classification of them as gras, blending them with food packaging materials based on dietary biopolymers attracts a great attention recently. polysaccharides (eg. chitosan, alginate) and proteins (such as soy and whey protein isolate, gelatin and zein) act as polymeric carriers for transporting a variety of bio active extracts like green tea extra...

Nowadays the application of nanotechnology in different biomedical fields such as drug delivery is increasing due to its unique advantages. With this in mind, it is widely believed that nanogels as the nanometer-sized networked polymeric particles have a considerable impact on drug delivery systems as biocompatible nanocarriers due to their unique characteristics such as high loading capacity, ...

Conventional transdermal drug delivery systems (TDDS) have been designed for drug delivery through the skin. These systems use the permeability property of stratum corneum, the outermost surface layer of the skin. Applying polymeric micro and nanofibers in drug delivery has recently attracted great attention and the electrospinning technique is the preferred method for polymeric micro-nanofiber...

Some recent developments in the preparation of polymeric reagents and their use in various chemical reactions are described. Improved polymeric acyl transfer reagents were prepared. They possess good mechanical properties and are therefore easy to handle and pure products are obtained by their use. With one of these polymeric reagents pure peptides may be obtained in high yield in reactions las...
