High-throughput cell-based screening has recently been emerging as a feasible technology for drug testing and discovery. However, currently available tools for electrical assaying are expensive, have limited reproducibility, and are unable to sustain long term studies. The Bioinstrumentation Laboratory at the Massachusetts Institute of Technology has developed a novel, 3D MEA for use in long te...

Abstract Numerous studies suggest that modification with functional nanomaterials can enhance the electrode electrocatalytic activity, sensitivity, and selectivity of electrochemical sensors. Here, a highly sensitive cost-effective disposable non-enzymatic glucose sensor based on copper(II)/reduced graphene oxide modified screen-printed carbon is demonstrated. Facile fabrication developed sensi...

Introduction In the underlying study we evaluated different single-use filtration systems for cell separation and harvest clarification in 1,000 L scale. A screening of different depth filters was carried out with various single-use filters from Pall, Cuno (3M), Millipore and Sartorius Stedim. In total, we included 85 depth filtrations in the screening. Out of that, two single-use filtration sy...

In a survey undertaken in the west of Scotland 801 adult diabetics taking insulin were questioned about their use of disposable or non-disposable needles and syringes, the life of such equipment, infected injection sites, and future preferences. Six hundred and eight preferred to use disposable equipment even if it meant reusing it; of the 413 who already bought disposable needles, 211 reused t...

In this study, a wall-jet flow cell with a GRC (graphite reinforced by carbon) electrode was designed for the amperometric detection of phenol and chlorophenols in liquid chromatography. The voltammetric responses of these analytes at the GRC electrodes are very similar to those at conventional glassy carbon electrodes. As the GRC electrodes were made of the same materials as commercially avail...

In this study, the measurement system was developed to measure ECG conveniently in an ubiquitous health care environment. The new-developed system consisted of hardware and software. The hardware system eliminated the inconvenience like connecting and disconnecting electrodes and extended the life span of these electrodes. According to Lead I ECG measurement, the metal mesh electrodes were atta...
