Abstract

A monitoring apparatus useful in detecting viability of biological cells. A substrate defines a microscopic chamber. One or more microcantilevers extend from the substrate into the chamber. A detector is operatively connected to the microcantilevers for sensing a state of deformation thereof. On each microcantilevers is deposited a layer of an environmentally sensitive hydrogel polymer having a configuration changing in accordance with presence of an environmental parameter.
