    Jan 27, 2012 · The reservoir-based system is one of the most common controlled drug delivery systems to date. In these systems, a drug core is surrounded by a polymer film, and the drug release rate is controlled by the properties of the polymer (e.g., polymer composition and molecular weight), the thickness of the coating, and the physicochemical properties of the enclosed drug, such as solubility, …Author: Wan-Wan Yang, Erik Pierstorff

    store drug molecules in each reservoir in the range of ‘a few to tens of micrograms per each reservoir’ [23, 28]. In this study, we investigated the possibility of ‘wet’ μCP to transfer and load drug molecules in the quantity of a few micrograms, particularly suited for micro-reservoir-type drug delivery systems (DDS) (figure 1). As shown

    Similarly, Spieth et al. proposed another micro-reservoir-based implantable micropump for passive drug delivery .Each micro-reservoir was preloaded with 0.25 μL of drug solutions before implantation, and the drug was displaced from the reservoirs due to local and irreversible thermal expansion by short heating pulses applied to a polydimethylsiloxane (PDMS) layer containing Expancel microspheres.Author: Sharma T.

    transferring the drug from a solid drug reservoir embedded within the patch to deliver it to the patient. As an easy-to-use and discreet delivery method, microarray patches hold promise for self-administration, which could expand access to drug treatment and prevention strategies in a range of outpatient settings. Moreover, some patches could be
