abstractvarious nanoparticles have been investigated as novel drug delivery systems, including solid lipid nanoparticles (slns). due to their rapid clearance from systemic circulation, nanoparticles do not provide sustained action in most cases. different strategies have been employed to overcome this problem. in this direction, the present study introduces erodible in-situ forming gel systems ...

A paradigm shift in drug delivery systems have been noted recently. The focus nowadays is to obtain maximum benefit with lower side effects. It is a monetary burden to launch newer molecules hence the industry is concentrating on improving the efficacy of existing molecules. Thus controlled release, target controlled infusion and closed loop infusion have entered the scene. Applying pharmacokin...

Transdermal administration of drugs is generally limited by the barrier function of the skin. Colloidal systems are one of the most contentious methods for transdermal delivery of active substances across the skin. The colloidal systems helps in overcoming the shortcomings associated with transdermal drug delivery systems and provide sustained and controlled release of drugs. This review presen...

Analytical aspects of chemically modified electrodes (CMEs) are critically reviewed. Effects of analyte and/or reagent accumulation, chemical transformation, electrocatalysis, permeability, ionic equilibria, controlled release, and change of mass, as well as combinations of these effects are evaluated and classified. Also, relevant definitions are provided and recommendations formulated for the...

The exine coatings of spores can be used to encapsulate drug molecules. We have demonstrated that these microcapsules can be filled with a commercial gadolinium(III) MRI contrast agent (in this proof of concept study Gd-DTPA-BMA was used) which is slowly released in plasma due to enzymatic digestion of the capsule.
