| Abstract | Cytochrome P450s (CYPs) are a large family of heme-containing monooxygenase enzymes involved in the first-pass metabolism of drugs and foreign chemicals in the body. CYP reactions, therefore, are of high interest to the pharmaceutical industry, where lead compounds in drug development are screened for CYP activity. CYP reactions in vivo require the cofactor NADPH as the source of electrons and an additional enzyme, cytochrome P450 reductase (CPR), as the electron transfer partner; consequently, any laboratory or industrial use of CYPs is limited by the need to supply NADPH and CPR. However, immobilizing CYPs on an electrode can eliminate the need for NADPH and CPR provided the enzyme can accept electrons directly from the electrode. The immobilized CYP can then act as a biosensor for the detection of CYP activity with potential substrates, albeit only if the immobilized enzyme is electroactive. The quest to create electroactive CYPs has led to many different immobilization strategies encompassing different electrode materials and surface modifications. This review focuses on different immobilization strategies that have been used to create CYP biosensors, with particular emphasis on mammalian drug-metabolizing CYPs and characterization of CYP electrodes. Traditional immobilization methods such as adsorption to thin films or encapsulation in polymers and gels remain robust strategies for creating CYP biosensors; however, the incorporation of novel materials such as gold nanoparticles or quantum dots and the use of microfabrication are proving advantageous for the creation of highly sensitive and portable CYP biosensors. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
