ABSTRACT
The Microspongesdelivery system are extremely small, inert,indestructibleclusters of even tinierspherical particles of microscopic sizepatented polymeric delivery systems consisting of porous microspheres that can entrap a wide range of active ingredients such as emollients, fragrances, essential oils, sunscreens, and anti-infective, anti-fungal, and anti-inflammatory agents and are very well tolerated, and highly efficacious, novel productsthat do not pass through the skin, capable of holding four times their weight in skin secretionsand can absorb skin secretions. Like a true sponge, each microspheres consists of a myriad of interconnecting voids within a non-collapsible structure with a large porous surface. The size of the microsponges can be varied usually from 5-300µm in diameter, depending upon the degree of smoothness or after-feel required for the end formula. Although the microsponge size may vary, a typical 25µm sphere can have up to 250000 pores and an internal pore structure equivalent to 10ft in length providing a total pore volume of about 1ml/g. This results in a large reservoir within each microsponge, which can be loaded with up to its own weight in active agent. The microsponge particles themselves are too large to be absorbed into the skin and this adds a measure of safety to these microsponge materials. Another safety concern is the potential bacterial contamination of the materials entrapped in the microsponge. Because the size of the pore diameter is smaller than bacteria, ranging from 0.007 to 0.2µm, bacteria cannot penetrate into the tunnel structure of the microsponges.The microsponge system can prevent excessive accumulation of ingredients within the epidermis and the dermis. Potentially, the microsponge system can reduce significantly the irritation of effective drugs without reducing their efficacy.

ABSTRACT
In recent years there has been a rapid increase in nanotechnology in the fields of medicine and more specifically in targeted drug delivery. The proprietary powder processing techniques use by nanotherapeutics improves the delivery of drug that can not normally taken orally.
It improves
·         Safety and efficacy of low molecular weight drugs,
·         Stability and absorption of proteins that normally cannot be taken orally,
·         Extend the life cycle of existing drug formulation.

At present many substances are under investigation for drug delivery and more specifically for cancer therapy, AIDS and potential to cross the Blood Brain Barrier (BBB) has open new ways for drug delivery into the brain. Pharmaceutical sciences are also using nanoparticles to reduce toxicity and side effects of drugs. Nanoparticles are also have the potential as novel intravascular or cellular probes for both diagnostic and therapeutic purposes (drug/gene delivery) and nanosize allow access into cell and cell compartment including nucleus. . Discovery of nanomedicine has given rise to nanoparticles through which better target specific drug and gene delivery is possible. In conclusion nanoparticles for drug delivery and imaging have gradually been developed as new modalities for cancer therapy and diagnosis. This review illustrates the emerging role of nanotechnology in drug delivery.

Abstract:
Selective estrogen receptor modulators, called SERMs for short, blocks the naturally circulating estrogen in breast tissues and other estrogen-sensitive tissues in the body. Each estrogen receptor has a slightly different structure, depending on the kind of cell it is in. If a SERM binds to a estrogen receptor, there is no site available for estrogen to bind and it can't attach to the cell. SERMs are called "selective" because they bind to particular estrogen receptors. This selective binding action is sometimes called estrogen inhibition, or estrogen suppression.

Introduction:
Natural polymer: A number of natural or partially modified polymers were screened for mucoadhesive properties by routinely measuring the force of detachment for swollen polymer films from pig intestinal mucosa in a saline medium. Suprisingly, hydroxypropyl- and carboxymethylcellulose showed almost no mucoadhesion, whereas the cationic polymer chitosan was fairly mucoadhesive in comparison to Polycarbophil as a reference substance. It is suggested that a strict difference be made between mucoadhesion of dry polymers on a wet tissue in air, and mucoadhesion of a swollen hydrogel in the presence of a third liquid phase. Cationic polymers should be further investigated with respect to possibly improved mucoadhesive properties in a neutral or slightly alkaline environment.
