MEMS for Drug Screening Applications

Zhou J., Zurn S., Markus D., Mantell S.C., Polla D., Smith G., University of Minnesota, US

MEMs offer a quick, low cost method for screening new drugs. In this MEMs application, microbeams were designed such that an affinity between the beam surface (coated with a biomolecule) and a second biomolecule (simulating [...]

Electrically Triggered Hydrogels: Mathematical Models and Simulations

Chatterjee A.N., De S.K., Aluru N.R., University of Illinois, US

Environmentally sensitive hydrogels have enormous potential in various applications. Ionic polymer gels have been shown to respond to a number of different stimuli like pH and electric field. One of the major advantages of electro-responsive [...]

Modeling the Interaction between Bristle Elastic Structures and Fluids

Botkin N.D., Hoffmann K-H, Starovoitov V.N., Turova V.L., Center of Advanced European Studies and Research, DE

The interaction of a solid multi-layered structure with a fluid is studied. Such a problem arises when modeling HPSW sensors operating in liquids. The surface of HPSW biosensors is covered by specific receptors called aptamers. [...]

A Micro Cantilever-based Pathogen Detector

Weeks B.L., Camarero J., Noy A., Miller A.E., Stanker L., De Yoreo J.J., Lawrence Livermore National Laboratory, US

Increasing efforts have been put into the developments of cantilever-based micro sensors. These devices show fast responses, high sensitivity, and are suitable for mass production. Currently, they are mainly applied for quality and process control, [...]

Macromolecular Crystallization in Microfluidics for the International Space Station

Monaco L.A., Spearing S.F., Morgan Research Corporation, US

Macromolecular Crystallization in Microfluidics for the International Space Station At NASA’s Marshall Space Flight Center in Huntsville, Alabama, we have begun the development of scientific hardware for macromolecular crystallization on the International Space Station (ISS). [...]

Hardware Implementation of Programmable Neural Networks for CHEMFET Signals Analysis in SEWING Project

Klepaczko A., Napieralski A., Kielbik R., Moreno J.M., Technical University of Lodz, PL

This paper focuses on problems of hardware implementation of neural networks (NN) in the re-programmable structures. New class of these devices, which integrate in one silicon wafer entire microprocessor systems (Systems-on-Chip), facilitates NN construction and [...]

Design and Modelling of Smart Sensor Dedicated for Water Pollution Monitoring

Szermer M., Daniel M., Napieralski A., Technical University of Lodz, PL

In this paper the smart sensor of chemical signal is presented. It reflects the current state of research performed in the System for European Water Monitoring (SEWING) project. The aim of the paper is to [...]

The Microchips for Alzheimer Disease Diagnosis

Napieralska M., Zubert M., Napieralski A., Liberski P.P., Technical University of Lodz, PL

The Alzheimer disease is belongs to a group of neurodegenerative diseases characterised by an accumulation of extraneuronal filamentous material consisting of _-sheet proteins of various biochemical properties. Clinically, these diseases manifest as dementia is permanent [...]

Multi- and Single- Atoms Liquid Flow Systems for Nano-sized channels

Lu M-C, Tseng F-G, Hsieh H-M, Chieng C-C, National Tsing Hua University, TW

Flow based assays use continuous forward flow in micro/nano-fluidic systems to deliver and transport biomedical sample to destined spots for biomedical diagnosis. Accurate dose control, less drag force from contact surface, and simpler flow system [...]

Visualization of Fluidic and Reaction Dynamics in Microchannels

Kawazumi H., Muraki A., Kanno K., Maeda H., Kinki University, Kyushu, JP

An easy-to-use and low cost microreactor made of polymethylmethacrylate was mechanically fabricated with a microchannel. The laminar flow behavior was investigated by visualizing the flow of red and green aqueous solutions. Digitized color images from [...]
