1. A body-insertable apparatus comprising:
- an array of probes, each of the probes comprising at least one probe material having an affinity for one or more constituent molecules in a body;
a light source capable of generating light, wherein the generated light impinges upon at least one probe material and causes a secondary light to be emitted from the probe material when the probe material is linked to a molecule to which the probe material has an affinity;
a detector for detecting the secondary emission of light of at least one of the probe materials and for converting the secondary emission of light to electrical signals, the light source, the probes, and the detector adapted for placement together in an area of interest within a body.

Abstract
A disposable high density optically readable polydeoxynucleotide array with integral fluorescence excitation and fluorescence emission channels is described. The compact array size allows integration into several types of interventional devices such as catheters, guidewires, needles, trocars and may be used intraoperatively. Highly sensitive monitoring of the metabolic and disease pathways of cells in vivo under varying chemical, genetic and environmental conditions is afforded.
