Combining Rigorously Controlled Crevice Geometry and Computational Modeling for Study of Crevice Corrosion Scaling Factors

Microfabrication methods have been used to construct crevice formers of rigorously controlled gap and length. These have been used to study the IR-controlled crevice corrosion of Ni200 in 0.5 M H2SO4 to determine the effect of crevice gap ~G! on the position of the accelerated attack (xcrit) within the crevice. The experimental results were then compared to the results of computational studies....

First-in-human testing of a wirelessly controlled drug delivery microchip.

The first clinical trial of an implantable microchip-based drug delivery device is discussed. Human parathyroid hormone fragment (1-34) [hPTH(1-34)] was delivered from the device in vivo. hPTH(1-34) is the only approved anabolic osteoporosis treatment, but requires daily injections, making patient compliance an obstacle to effective treatment. Furthermore, a net increase in bone mineral density...

Mechanical Force-Triggered Drug Delivery.

Advanced drug delivery systems (DDS) enhance treatment efficacy of different therapeutics in a dosage, spatial, and/or temporal controlled manner. To date, numerous chemical- or physical-based stimuli-responsive formulations or devices for controlled drug release have been developed. Among them, the emerging mechanical force-based stimulus offers a convenient and robust controlled drug release ...

Biotin-guided anticancer drug delivery with acidity-triggered drug release.

A novel biotin-guided anticancer drug delivery system, prodrug , consisting of biotin, nitrobenzene, and doxorubicin, with acid-triggered drug releasing capability was synthesized. Its cellular uptake and anticancer activity are selective to the HepG2 cell line over the WI-38 cell line, as revealed by fluorescence confocal microscopic experiments and MTT assay.

A robust, electrochemically driven microwell drug delivery system for controlled vasopressin release.

Micro-electro-mechanical-system (MEMS) based implantable drug delivery devices represent a promising approach to achieving more precise dosing, faster release and better localization of therapeutic compounds than is possible with existing technology. Despite recent advancements, there remain challenges in being able to build systems that enable active control over the dose rate and release time...
