Ai Targeted Delivery

Targeted Delivery Foundations

Doctoral work examines directing therapeutic agents toward specific tissues or cells. Targeting raises efficacy while reducing exposure of healthy tissue.

Drug Delivery Principle Research

Research examines fundamental principles governing how therapeutics reach their site. Delivery frequently limits efficacy more than the molecule itself.

Targeting Concept Research

Doctoral study examines what targeting means and how it should be demonstrated. Claimed targeting frequently exceeds what evidence actually supports.

Active Targeting Research

Research examines carriers bearing ligands binding specific cellular receptors. Active binding improves uptake once carriers reach the target tissue.

Passive Targeting Research

Doctoral work examines accumulation arising from tissue and carrier properties alone. Passive accumulation dominates most currently approved delivery systems.

Biodistribution Research

Research examines where administered agents actually travel within the body. Most delivered material reaches organs other than the intended target.

Pharmacokinetic Research

Doctoral study examines absorption, distribution and elimination of delivered agents. Carrier systems change kinetics profoundly compared with free molecules.

Clearance Mechanism Research

Research examines processes removing delivered material from the circulation. Rapid clearance prevents carriers ever reaching their intended destination.

Renal Clearance Research

Protein Corona Research

Doctoral work examines blood proteins adsorbing onto carrier surfaces immediately. The adsorbed layer determines what cells actually recognise.

Opsonisation Research

Research examines proteins marking circulating carriers for immune removal. Opsonisation is the first step toward rapid clearance of carriers.

Immune Recognition Research
