“…As we will argue here, colorimetric sensor arrays provide a successful method of dealing with the dilemma of sensor sensitivity vs. robustness. In many ways, colorimetric sensor arrays revisit the earlier, pre-electronic era of analytical chemistry, [111][112][113] updated by the addition of modern digital imaging easily quantified by digital imaging. 7,17,[114][115][116] and pattern recognition techniques (discussed in Section 3).…”

“…The simple precipitation of metal salts or formation of metal nanoclusters on reaction with thiols and sulfides goes back to the earliest qualitative spot tests. 111,112 The recent cutting edge is represented by control over the nanostructure of optical sensors. For example, gold nanoparticle (NP) agglomerates that efficiently quench adsorbed fluorophores; analyte binding can disperse such nanoparticle agglomerates and create a fluorescence turn-on.…”

A comprehensive review is presented on the development and state of the art of colorimetric and fluorometric sensor arrays. Optical arrays based on chemoresponsive colorants (dyes and nanoporous pigments) probe the chemical reactivity of analytes, rather than their physical properties. This provides a high dimensionality to chemical sensing that permits high sensitivity (often down to ppb levels), impressive discrimination among very similar analytes and exquisite fingerprinting of extremely similar mixtures over a wide range of analyte types, both in the gas and liquid phases.

The protocol of rapid identification system consists of three chemical color reactions; two group tests for fluoroquinolone class and a compound specific test each for norfloxacin, ciprofloxacin, gatifloxacin, ofloxacin, levofloxacin and sparfloxacin. The group color reactions are based on (a) Oxidizing behavior of quinolone and (b) Fluorine functional groups, both of which are characteristic of fluoroquinolone class. The compound specific color reactions are developed taking into consideration unique chemical behavior of each compound. The proposed chemical color tests have high selectivity⁄specificity, are ideal for screening purpose. The color of each test was defined by two standard color systems namely CIE lab and Munsell color. A suspected counterfeit tablet of any of the above mentioned drugs can be identified within 10-15 min using this rapid identification system.
