32 � 32 pH Image Sensors for Real Time Observation of Biochemical Phenomena
32 x 32 pH image sensors were successfully fabricated by using the CCD/CMOS image sensor technique, and real time imaging of a chemical reaction and pH distribution was carried out for the first time. The pH variations by a chemical reaction are observed by 200 ms step (i.e. 5 flames per sec).

Plasmonic phenomena in metal nanoapertures and chip-scale instrumentation for biochemical sensing
Plasmonic interactions in the metallic nanoaperture array allow for rich phenomena, such as concentration and channeling of light in the subwavelength scale structures. We present high-sensitivity surface plasmon resonance spectroscopy based on a metal nanoslit array. Strong confinement of optical fields in the slit region allows sensitive transduction

We address the problem of fast and accurate computational analysis of large networks of coupled oscillators arising in nanotechnological and biochemical systems. Such systems are computationally and analytically challenging because of their very large sizes and the complex nonlinear dynamics they exhibit.

Cellular automata models of biochemical phenomena
Future Generation Computer Systems, 1999Abstract This paper describes the use of kinematic, asynchronous, stochastic cellular automata to model water and solution phenomena encountered in complex biological systems. These in silico experiments are designed to assess the ability of the dynamic simulations to model some physical properties observed in solutions.

Biochemical factors influencing erythrocyte deformability and capillary entrance phenomena
Scandinavian Journal of Clinical and Laboratory Investigation, 1981Evaluation of the effects of biochemical modification of erythrocytes by low pressure filtration through Nuclepore filters of 2.8 and 3.0 micrometer pore diameter and glass micropipettes of 2.7 and 3.0 micrometer internal diameter and channel length greater than 100 micrometer indicates the relative sensitivity of the micropipette in detection of ...

Finding complex oscillatory phenomena in biochemical systems An empirical approach
Biophysical Chemistry, 1988Starting with a model for a product-activated enzymatic reaction proposed for glycolytic oscillations, we show how more complex oscillatory phenomena may develop when the basic model is modified by addition of product recycling into substrate or by coupling in parallel or in series two autocatalytic enzyme reactions. Among the new modes of behavior are

Hydrophobic hydrophilic phenomena in biochemical processes
Biophysical Chemistry, 2003The evolution of concepts developed in the study of the hydrophobic affect is surveyed, within the more general context of solvent-induced effects. A systematic analysis of the solvent-induced contribution to the driving force for the process of protein folding has led to two important modifications in our understanding of these effects.
