Biopharmaceutics examines the interrelationship of the physical/chemical properties of the drug, the dosage form (drug product) in which the drug is given, and the route of administration on the rate and extent of systemic drug absorption. Biopharmaceutics is the study that shows how the drug absorption rate is affected by various factors like physical and chemical factors of the drug and the route through which the drug is administered. Biopharmaceutics includes the stability of the drug, liberation of the API from the dosage form, rate, or the extent of drug release and rate of conversion of drug to the solution.

Biopharmaceuticals are medical drugs that are prepares by using biotechnology. microarray technology may be defined as a high-throughput and versatile technology used for parallel gene expression analysis for thousands of genes of known and unknown function, or DNA homology analysis for detecting polymorphisms and mutations in both prokaryotic and eukaryotic genomic DNA.
