Chemical sensors, nanoscience

Capitalizing on self-assembly and nanoscience will enhance the ability to screen drugs for individual sensitivities. Advances in drug discovery, combinatorial synthesis, and screening with sensors that have the ability to detect multitudes of specific genetic matches—marrying microelectronics and self-assembly—are expected to be near-term breakthroughs. Then the creation of advanced forms of in the field or in the office tests for chemical risks, pharmaceutical compatibility, or environmental hazards will be possible. 

New and highly efficient synthetic routes have generated many porphyrinlike compounds with unique characteristics for their uses in several other applications like oxidative catalysis [ 19,20] and as biomimetic model systems of the primary processes of photosynthesis [21,22]. Presently, the interest includes also the supramolecular units, including molecular recognition in chemical receptors and sensors [23-25], use as light-harvesting devices [26-29], and as materials for advanced technologies, mainly in nanosciences [30, 31].
