Wafer-Level Manufacturing of MEMS H Sensing Chips Based on Pd Nanoparticles Modified SnO Film Patterns.

In this manuscript, a simple method combining atomic layer deposition and magnetron sputtering is developed to fabricate high-performance Pd/SnO film patterns applied for micro-electro-mechanical systems (MEMS) H sensing chips. SnO film is first accurately deposited in the central areas of MEMS micro hotplate arrays by a mask-assistant method, leading the patterns with wafer-level high consistency in thickness. The grain size and density of Pd nanoparticles modified on the surface of the SnO film are further regulated to obtain an optimized sensing performance.

Amyloid light chain (AL) amyloidosis is a rare hematologic disease that may involve multiple organs. Amongst the organs, cardiac involvement causes the greatest concern as its treatment is challenging. Diastolic dysfunction rapidly progresses to decompensated heart failure, pulseless electrical activity, and atrial standstill due to electro-mechanical dissociation resulting in death.

Objective: Postinfarction left ventricular free wall rupture (FWR) has been classified into blow-out type and oozing type. However, considering past papers, oozing type included the cases in which the bleeding had spontaneously stopped or sealed, and the distinction between blow-out type and oozing type was not always clear. We classified FWR into the BO type (combination of blow-out type and oozing type) with continuous bleeding and sealed type and clarified the pathophysiology of the sealed type.

We report a mathematical model for ion transport and electrical impedance in zwitterionic hydrogels, which possess acidic and basic functional groups that carry a net charge at a pH not equal to the isoelectric point. Such hydrogels can act as an electro-mechanical interface between a relatively hard biosensor and soft tissue in the body. For this application, the electrical impedance of the hydrogel must be characterized to ensure that ion transport to the biosensor is not significantly hindered.
