Enzyme activation for activator and enzyme activity measurement
Biosensors and Bioelectronics, 1993A new sensing principle of enzyme activation is demonstrated for the determination of glycogen phosphorylase b and its allosteric effector AMP. As the indicator of the phosphorylase catalysed glycogen phosphorolysis, glucose-1-phosphate formation has been detected with an enzyme sequence comprising coentrapped alkaline phosphatase, mutarotase and ...

Active packaging with antifungal activities
International Journal of Food Microbiology, 2016There have been many reviews concerned with antimicrobial food packaging, and with the use of antifungal compounds, but none provided an exhaustive picture of the applications of active packaging to control fungal spoilage. Very recently, many studies have been done in these fields, therefore it is timely to review this topic. This article examines the

Light‐Activated Active Colloid Ribbons
Angewandte Chemie, 2017AbstractWe report a dynamic self‐organization of self‐propelled peanut‐shaped hematite motors from non‐equilibrium driving forces where the propulsion can be triggered by blue light. They result in one‐dimensional, active colloid ribbons with a positive phototactic characteristic.

Activation of a gene activator
Immunology Today, 1987Differential gene expression is fundamental to the existence of any complex metazoan organism: certain genes are only expressed in some cell types while others are turned on and off at specific stages in a developmental pathway. These changes in expression are activated by intracellular and extracellular signals - molecules that trigger a specific ...
