Microfabrication of a Device to Evaluate the Swelling of Glucose Sensitive Hydrogels Under Isochoric Conditions
David Barriet,Ronald A. Siegel +1 more
TL;DR: In this paper, the authors used a commercial pressure die with a very small piezoresistive element (500μm by 500μm), and packaged it such that the pressure sensitive membrane was in contact with a hydrogel sample a few tens of μm thin separated from the external environment by a commercial Anodisc? membrane (0.02 and 0.2 μm pore diameter).

Laser-scribed ferrogel sensor with magnetic particles

- 01 Dec 2014
TL;DR: In this article, the authors propose a method of making a sensor that includes depositing a layer of hydrogel over a substrate, the hydrogels configured to change thickness or volume in response to a selected condition and including a plurality of magnetic particles disposed in the water, so that a magnetic property of the water changes with changes of thickness or volumetric volume.

Diazepam Prodrug Stabilizes Human Aminopeptidase B during Lyophilization
TL;DR: This study demonstrates the use of the substrate avizafone (AVF), a prodrug for diazepam, as a stabilizer to minimize inactivation of APB during lyophilization, and suggests the combination of substrate and trehalose provides a greater stabilizing effect than either additive alone.

Examination of a Shannon entropy-like figure of merit for controlled release of drugs and other molecules
Ronald A. Siegel,Di Wu +1 more
TL;DR: In this paper, the authors propose a figure of merit, based on temporal entropy, to evaluate the degree to which a controlled drug release system is able to adhere to its target release pattern.
