    Abstract: Aspects and embodiments relate to a target detector; a method of detecting a change in a target, target monitoring apparatus and a method of monitoring a target. One aspect provides a target detector comprising: a structure comprising: a gain medium comprising a plurality of disordered nanostructure features and a target-sensitive material; the structure being configured, when pumped, to support random lasing and to exhibit a change in the gain of the gain medium and the random lasing in response to a change in the target. Aspects recognise that it is possible to use an appropriately fabricated random laser material as a detector or sensor for a target. In particular, the first aspect recognises that it is possible to perform sensing operations by utilizing the properties of random lasing. That target may, for example, comprise a change in a physical parameter of an environment adjacent, surrounding or permeating the random laser material.
