Biosensors Biosensor is a device, probe or electrode consisting of an immobilized enzyme (biocatalyst). It is an analytical device which converts a biological response into an electrical signal. Professor Leland C. Clark is the father of biosensor. He published first example of enzyme electrochemical biosensor by entrapping glucose oxidase in dialysis membrane over a Clark-type … Read more

Brief Introduction to Protein Engineering

Protein engineering Protein engineering is the process of developing useful or valuable proteins. It is the new branch of biotechnology which understands protein folding and recognition for design principles. It is the second generation of recombinant DNA technology. It involves altering cloned DNA in vitro by novel mutational technique so that translated proteins have slightly … Read more

Enzyme biotechnology- Methods of Enzyme Immobilisation and Applications

Enzyme biotechnology Enzymes (biocatalyst) are the functional proteins which facilitated the execution of biochemical reactions. Enzymes provide suitable environment for the normal functioning, growth and proliferation of any living system. The enzymes work in mild temperature, pressure, pH, substrates specificity under suitable reaction conditions and for the production of desired products without any contaminations. Enzymes … Read more

Biotechnology with reference to pharmaceutical sciences

Introduction Biotechnology is the multidisciplinary field that involves the integration of natural sciences and engineering sciences in order to achieve the application of organisms, cells, parts and molecular analogues for products and services. The concept of biotechnology encompasses a wide range of procedures for modifying living organisms for human purposes, cultivation of plants and breeding … Read more
