Abstract
An optical sensor comprising a waveguide having a sensing layer which is molecularly imprinted such that it will receive and retain target entities to be sensed, the optical sensor further comprising a detection apparatus arranged to detect a change of an optical property of the waveguide which occurs when the target entities are received and retained in the sensing layer.

An optical sensor comprising a leaky mode waveguide having a sensing layer which is molecularly imprinted such that it will receive and retain target entities to be sensed, the optical sensor further comprising a detection apparatus arranged to detect a change of an optical property of the leaky mode waveguide which occurs when the target entities are received and retained in the sensing layer, and wherein the optical sensor forms part of a contamination detector which is part of a purification system.
