Judicious component selection, low cost light sources and simple electronics, will help in further reducing instrument cost as will the use of multiple analyte sensing with one instrument. Coupled with advances in chemistry, it is conceivable that the next generation of bioprocess and clinical sensors will rapidly move into the... 

Although composed of weak and overlapping spectral features, near-infrared spectra can be used to extract analytical information from complex sample matrices. Chemical sensing with in-line near-infrared spectroscopy is a general technique that can be used to quantify multiple analytes in complex matrices, often without reagents or sample pretreatment.7-9 Applications are widespread in the food sciences, agricultural industry, petroleum refining, and process analytical chemistry.10-13 These activities demonstrate that near-infrared spectroscopy can provide selective and accurate quantitative measurements both rapidly and nondestructively. 

Microcantilever-based sensing satisfies many requirements for an ideal explosive sensor. Microcantilever sensors have extremely high sensitivity and are compatible with array arrangement for simultaneous detection of multiple analytes. They have the advantages of low power consumption and miniature size. However, microcantilever... 

The power of array sensing is most apparent when discriminating multianalyte solutions. In such solutions, multiple compounds (possibly hundreds or even thousands) make up each mixture. Array sensing is ideal for such a situation, with its inherent ability to detect multiple analytes simultaneously using various differential sensors, especially in circumstances where the multianalyte solutions have only subtle differences in chemical compositions. The resultant fingerprint response achieved for each solution allows discrimination through pattern recognition.
