Pharmacogenomics is the study of the role of the genome in drug response. Its name reflects it’s combining of pharmacology and genomics. Pharmacogenomics analyzes how the genetic makeup of an individual affects his/her response to drugs. It deals with the influence of acquired and inherited genetic variation on drug response in patients by correlating gene expression or single-nucleotide.
Biological marker is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. Biomarkers are used in many scientific fields.
Forensic chemistry is the application of chemistry to law enforcement or the failure of products or processes. Many different analytical methods may be used to reveal what chemical changes occurred during an incident, and so help reconstruct the sequence of events. The wide techniques that come under forensic chemistry are Capillary electrophoresis in forensic chemistry, chemical analysis of forensic evidence, Case studies of drug profiling, Method development and applications of LC-MS/MS in forensic analysis which is used for the identification of the drug products.
