Applications in Biology

We will give several examples to illustrate the many possible applications of laser spectroscopy in the investigation of problems in molecular biology.

In the first part of the present review, new techniques of preparation of modified electrodes and their electrochemical properties are presented. The second part is devoted to applications based on electrochemical reactions of solute species at modified electrodes. Special focus is given to the general requirements for the use of modified electrodes in synthetic and analytical organic electrochemistry. The subject has been reviewed several times Besides the latest general review by Murray a number of more recent overview articles have specialized on certain aspects macro-molecular electronics theoretical aspects of electrocatalysis organic applicationssensor electrodes and applications in biological and medicinal chemistry. 

Applicability in biological ion assay is an important factor for biocompatible potentio-metric ion sensors. Attempts were made to determine Na" " concentrations in human blood sera by using silicone-rubber membrane Na+-ISFETs based on (5) [Fig. 17(a)] [29]. The found values for Na concentration in undiluted, 10-fold diluted, and 100-fold diluted serum samples are in good agreement with the Na" " calibration plots. Even in the undiluted serum samples, only a slight potential shift was observed from the calibration. This indicates that the calixarene-based silicone-rubber-membrane Na+-ISFETs are reliable on serum Na assay. For comparison with the silicone-rubber membrane, Na -ISFETs with corresponding plasticized-PVC membrane containing (2) or (5) were also tested for the Na assay. The found values of Na" " concentration...

In a similar fashion, steroids are molecules that have been investigated by disruption of FRET. The sensor is a double labeled peptide with cyclodextrin bound to one side chain. The latter keeps the fluorophores closely together by accommodating the coumarin into its cavity thereby ensuring efficient FRET. Steroids compete for the cavity of cyclodextrin and displace the coumarin reducing FRET efficiency. This model, although useful for in vitro applications, seems to be poorly selective for its application in biological samples [95],... 

The above historical outline refers mainly to the EPR of transition ions. Key events in the development of radical bioEPR were the synthesis and binding to biomolecules of stable spin labels in 1965 in Stanford (e.g., Griffith and McConnell 1966) and the discovery of spin traps in the second half of the 1960s by the groups of M. Iwamura and N. Inamoto in Tokyo A. Mackor et al. in Amsterdam and E. G. Janzen and B. J. Blackburn in Athens, Georgia (e.g., Janzen 1971), and their subsequent application in biological systems by J. R. Harbour and J. R. Bolton in London, Ontario (Harbour and Bolton 1975).

The book is organized into three major parts which cover important and emerging methods and applications in biological and pharmacological research. 

Today, AIMD is extensively applied in different fields of computational chemistry and, certainly, because cell functions occur at approximately 310 K, its use in life sciences seems particularly appropriate, because of the importance of temperature effects in biological systems. In this respect AIMD, which accounts explicitly for the dynamic behavior at finite temperature, can be considered one of the methods of choice when performing DFT-based simulations in theoretical medicinal chemistry. Further details about AIMD and its applications in biological chemistry are available elsewhere [11]. 

Electrodes are capable of measurement at around the 1 ppm level. They are simple, robust and portable. As such there is considerable potential for their employment in ecological studies and they can provide constant monitoring of dissolved oxygen, e g. in river waters. The potential for their employment in monitoring industrial liquors is clear, as is their applications in biological investigations of oxygen transport.
