Biological and environmental importance

The use of MPc complexes as electrocatalysts for the detection of analytes relies on the formation of modified electrodes. Thiol, alkylthio, or arylthio substituted MPc complexes readily form self-assembled monolayers (SAMs) on gold. Amino substituted MPc complexes can easily be electropolymerized onto electrodes. Direct adsorption of the monomer onto electrodes (especially carbon electrodes) also occurs. The modified electrodes are then employed for detection of analytes ranging from neurotransmitters, thiols, phenols, and other biologically and environmentally important molecules. 

While a spectrum interpretation can be a very involved and tedious task while dealing with a new structure, many spectra need not be interpreted from the first principles . Once a spectrum has been recorded, it is now soon included into one of the growing libraries of mass-spectral information. Many thousands of mass spectra from biological and environmentally important substances have been acquired. A computer search for such compounds is a relatively straightforward task. A mass spectrum from a particular sample can be compared to the reference spectra that have been accumulated over the years. The individuals specializing in certain compound types may also have their own mass-spectral libraries. 

Probing biologically and environmentally important metal ions with fluorescent chemosensors 12CCR149. 

Tmmiinosensors offer high sensitivity, rapidity and simplicity of operation for screening of biologically and environmentally important target molecules. 

The use of immunosensors for monitoring biologically and environmentally important target molecules is well-established, and a variety of laboratory sensors have been developed. 

BDD MDA electrodes are useful for electrochemical detection of various biologically and environmentally important chemical species with high sensitivity and stability. Sigmoidal voltammograms could be obtained for (A) ascorbic acid and (B) 3,4-dihydroxyphenylacetic acid (DOPAC), as shown in Fig. 11.3. Steady-state current was observed even at potentials as high as +1.2 V vs Ag/AgCl, due to the wide potential window of BDD. 

The improved analytical performance of a diamond electrode for CE ED analysis has broadened the range of target chemicals to include many biologically and environmentally important compounds that exhibit high oxidation potentials and serious fouling problems. The CE-ED analysis of aromatic amines [13]...
