The impact of tissue glue in wound healing of head and neck patients undergoing neck dissection.

We investigated the impact of fibrin glue on postoperative drainage amount and duration in head and neck cancer patients who underwent neck dissection. This study was a prospective randomized controlled trial. Patients who were scheduled to undergo neck dissection due to head and neck cancer were eligible for this study.

A device design of an integrated CMOS poly-silicon biosensor-on-chip to enhance performance of biomolecular analytes in serum samples.

For on-site clinical diagnosis of biomolecules, the detection performances of most point-of-care (POC) biosensor devices are limited by undesired cross-detection of other non-analyte proteins in patient serum samples and other complex samples. To conquer this obstacle, this work presents a fully integrated bottom-gate poly-silcion nanowire (polySi NW) biosensor system-on-chip (SoC) to enhance the detection performance of cardiac-specific troponin-I (cTnI) concentration levels in serum samples. By applying proper electrical potential at the bottom gate under polySi NW biosensor, the biosensor response to cTnI biomarker can be improved by at least 16 fold in 50% phantom serum samples.

A CMOS cantilever-based label-free DNA SoC with improved sensitivity for hepatitis B virus detection.

This paper presents a highly-integrated DNA detection SoC, where several kinds of cantilever DNA sensors, a readout circuit, an MCU, voltage regulators, and a wireless transceiver, are integrated monolithically in a 0.35 μm CMOS Bio-MEMS process. The cantilever-based biosensors with embedded piezoresistors aim to transduce DNA hybridization into resistance variation without cumbersome labeling process.
