Surface modified multifunctional and stimuli responsive nanoparticles for drug targeting: Current status and uses

membrane... ❖In matrix type diffusion controlled drug delivery systems, the system is prepared by homogenously dispersing drug particle in rate controlling polymer matrix from either

❖ In this type controlled release mechanism, drug reservoir is in solution form retained in a container equipped with mechanically activated pumping system. ❖ A measured dose of

This relationship can be used to describe the drug dissolution of several types of modified release pharmaceutical dosage forms, as in the case of controlled release systems such as

This system is a simplified form of the membrane permeation- controlled system. Here the drug reservior is formulated by directly dispersing the drug in an adhesive polymer...

To prolong the retention time of topically applied drugs, anterior drug delivery systems for eye-drops utilizing interaction between drug carrier (excipients) and

In recent years many drugs have been shown to achieve better systemic bioavailability through nasal route than by oral administration... ➢ It is a useful delivery route for drugs

For example, superparamagnetic iron oxide nanoparticles (SPIONs) have a large magnetic susceptibility, and thus, they are widely used in clinics as contrast agents in
