ABSTRACT:
A concentrator for detecting biological and/or chemical materials in an environment. The concentrator comprises an engineered superlattice structure having alternating layers of elemental, binary or ternary group III-group V, or group IV-group IV semiconducting materials. A method for detecting biological and/or chemical materials in an environment using the concentrator. The method comprising exposing the concentrator to the biological and/or chemical materials in an environment and activating the superlattice structure optically or electrically followed by the detection of the biological and/or chemical materials.
