Knowing the kind of receptor on the cell for which the medicine will be targeted and using cell-specific ligands will enable the nanoparticle to attach exclusively to the cell that has the corresponding receptor. Cellular targeting is one method to actively target just sick tissue in the body. Intracellular delivery, a long-researched area in contemporary biotechnology, allows for effective medication administration into a variety of cell types. It is a crucial step in several cellular-level investigations, including gene delivery for gene editing and a number of biological research applications.
a. Targeted Drug Delivery System: A targeted drug delivery system is a specialised type of medication administration in which the drug is only delivered at the site of action and not to the target organs, tissues, or cells.
b. Drug Targeting and Design: The capacity of a drug to acquire in the target tissue or organ particularly, so that the concentration of drug will be high at the illness, while its concentration is low in non-target organs and tissues, preferably below the certain minimal level to prevent any toxic effects, is referred to as drug targeting.
The non-specific harmful impact of traditional medication administration can be reduced using drug targeting. Another name for drug design is rational drug design or just rational design.
