Biomedical analytical chemistry

Biomedical analytical chemistry happens to be one of the latest disciplines which essentially embraces the principles and techniques of both analytical chemistry and biochemistry. It has often been known as clinical chemistry . This particular aspect of analytical chemistry has gained significant cognizance in the recent past by virtue of certain important techniques being included very much within its scope of analysis, namely colorimetric assays, enzymic assays, radioimmunoassays and automated methods of clinical analysis. 

It is, however, important to mention here that certain other routine procedures also carried out in a clinical laboratory fall beyond the scope of biomedical analytical chemistry, namely microbiological assays, heamatological assays, serum analysis, urine analysis and assays of other body fluids. 

It will be very much within the scope of this chapter to discuss briefly the various important details, with specific examples wherever necessary, of volumetric analysis, gravimetric analysis and biomedical analytical chemistry. 

This particular aspect of analytical chemistry is the outcome of the unique amalgamation of the principles and techniques of analytical chemistry and biochemistry and was initially termed as clinical chemistry> but is more recently and more descriptively known as biomedical analytical chemistry . 

In order to have a comprehensive account on the various aspects of Biomedical Analytical. Chemistry , we may have to study the following four methods of assay with specific emphasis on their principle and applications, namely ... 

B. Applications in Biomedical Analytical Chemistry Colorimetric assays have a wide spectrum of applications in biomedical analytical chemistry which may be categorized under the following four heads, namely ... 

Part—I has three chapters that exclusively deal with General Aspects of pharmaceutical analysis. Chapter 1 focuses on the pharmaceutical chemicals and their respective purity and management. Critical information with regard to description of the finished product, sampling procedures, bioavailability, identification tests, physical constants and miscellaneous characteristics, such as ash values, loss on drying, clarity and color of solution, specific tests, limit tests of metallic and non-metallic impurities, limits of moisture content, volatile and non-volatile matter and lastly residue on ignition have also been dealt with. Each section provides adequate procedural details supported by ample typical examples from the Official Compendia. Chapter 2 embraces the theory and technique of quantitative analysis with specific emphasis on volumetric analysis, volumetric apparatus, their specifications, standardization and utility. It also includes biomedical analytical chemistry, colorimetric assays, theory and assay of biochemicals, such as urea, bilirubin, cholesterol and enzymatic assays, such as alkaline phosphatase, lactate dehydrogenase, salient features of radioimmunoassay and automated methods of chemical analysis. Chapter 3 provides special emphasis on errors in pharmaceutical analysis and their statistical validation. The first aspect is related to errors in pharmaceutical analysis and embodies classification of errors, accuracy, precision and makes...

Solvent extraction is used in nnmerons chemical industries to produce pure chemical compounds ranging from pharmaceuticals and biomedicals to heavy organics and metals, in analytical chemistry and in environmental waste purification. The scientific explanation of the distribution ratios observed is based on the fundamental physical chemistry of solute-solvent interaction, activity factors of the solutes in the pure phases, aqueous complexation, and complex-adduct interactions. Most university training provides only elementary knowledge about these fields, which is unsatisfactory from a fundamental chemical standpoint, as well as for industrial development and for protection of environmental systems. Solvent extraction uses are important in organic, inorganic, and physical chemistry, and in chemical engineering, theoretical as well as practical in this book we try to cover most of these important fields.

This book is intended to provide a background and training suitable for application of impedance spectroscopy to a broad range of applications, such as corrosion, biomedical devices, semiconductors and solid-state devices, sensors, batteries, fuel cells, electrochemical capacitors, dielectric measurements, coatings, elec-trochromic materials, analytical chemistry, and imaging. The emphasis is on generally applicable fundamentals rather than on detailed treatment of applications. The reader is referred to other sources for discussion of specific applications of impedance. ... 

Future markets for biomedical microdevices for human genome studies, drug discovery and delivery in the pharmaceutical industry, clinical diagnostics, and analytical chemistry are enormous (tens of billions of U.S. dollars).In the following sections, major bioMEMS applications and microfluidics relevant to bioMEMS applications are briefly introduced. Because of the very large volume of publications on this subject, only selected papers or review articles are referenced in this entry. 

Generally, it is not possible to discuss the capacity of an analytical technique without regarding the problem simultaneously. Normally, different analytical methods are necessary to solve the given problems. And by this, the various analytical techniques should be seen as complementary rather than comparative. Always, the problem demands an adequate technique. This Includes all the questions about the element, the matrix, the quantity of sample material available for the analysis, the application in practice (routine analysis of research), time consumption (especially important for diagnosis and/or therapy control), price of the analysis, etc. Only combinations of different analytical techniques can help in solving the various problems in trace element analytical chemistry in the biomedical and environmental fields. No serious analyst should try to solve every problem by one technique, which happens to be in the laboratory. This would be in most of the cases a violation of the method and should be avoided for internationally better and comparable results in trace element research and practical application.

Capillary column gas chromatography (GC)/mass spectrometry (MS) has also been used to achieve more difficult separations and to perform the structural analysis of molecules, and laboratory automation technologies, including robotics, have become a powerful trend in both analytical chemistry and small molecule synthesis. On the other hand, liquid chromatography (LC)/MS is more suitable for biomedical applications than GC/MS because of the heat sensitivity exhibited by almost all biomolecules. More recent advances in protein studies have resulted from combining various mass spectrometers with a variety of LC methods, and improvements in the sensitivity of nuclear magnetic resonance spectroscopy (NMR) now allow direct connection of this powerful methodology with LC. Finally, the online purification of biomolecules by LC has been achieved with the development of chip electrophoresis (microfluidics).
