Abstract
The invention relates to a method for observing a sample under optical microscopy, in incoherent, unpolarised light, using a sample substrate including a contrast-amplifying layer having a complex index of refraction. The invention also relates to a method for detecting or metering at least one chemical or biological species using such a sample substrate.
