Abstract
Apparatus and method are provided for monitoring and measuring matter and energy fluxes by use of devices able to detect refractive index changes. In one aspect, apparatus use an interference between two electromagnetic radiations in order to provide high sensitivity, enabling fluxes monitoring at the microscopic scale, by measuring phase changes or Optical Path Length (OPL) changes. In one aspect, methods are provided for monitoring and measuring the electrical activity of a biological cells, simultaneously on several cells, without use of electrodes and contrast agents.
