Ai Transdermal Delivery

Transdermal Delivery Foundations

Doctoral work examines delivering therapeutic agents through the skin into the body. Skin delivery avoids both injection and passage through the gut.

Skin Structure Research

Research examines the layered architecture of human skin and its organisation. Structural understanding underpins every approach to skin delivery.

Stratum Corneum Research

Doctoral study examines the outermost dead cell layer forming the main barrier. This thin layer excludes nearly everything applied to the skin.

Epidermis Research

Research examines the living outer skin layer beneath the surface barrier. Epidermal properties affect both permeation and local drug action.

Dermis Research

Doctoral work examines the deeper layer containing vessels and connective tissue. Reaching the dermis permits entry into the general circulation.

Skin Lipid Research

Research examines fatty material filling the space between surface skin cells. These lipids form the actual barrier that all agents must cross.

Corneocyte Research

Doctoral study examines the flattened dead cells making up the surface layer. Cell arrangement determines the tortuous route agents must follow.

Lipid Lamellae Research

Research examines the ordered lipid sheets arranged between surface skin cells. Lamellar organisation explains why the barrier is so effective.

Skin Appendage Research

Doctoral work examines follicles and glands penetrating through the skin barrier. Appendages occupy little area and offer continuous open routes.

Hair Follicle Research

Research examines follicles as a route for agents entering the skin. Follicles matter especially for particles that cannot cross the barrier.

Sweat Gland Research

Doctoral study examines sweat ducts as potential routes for delivered agents. Outward sweat flow opposes inward movement of applied material.

Sebaceous Gland Research

Research examines oil producing glands and their relevance to skin delivery. Sebum affects how applied formulations spread and are absorbed.

Skin Barrier Function

Doctoral work examines how skin excludes external substances so effectively. Barrier function protects the body and obstructs intended delivery.

Barrier Recovery Research

Research examines skin repairing itself after a delivery method disrupts it. Recovery speed determines how long enhanced permeation persists.

Skin Hydration Research

Doctoral study examines water content held within the outer skin layers. Hydration substantially increases permeability to many applied agents.

Skin Permeability Research

Research examines how readily substances pass through intact human skin. Permeability differs by orders of magnitude between differing molecules.

Permeation Pathway Research

Doctoral work examines the routes molecules follow when crossing the skin. Pathway identification guides how enhancement should be attempted.

Intercellular Pathway Research

Research examines molecules travelling within lipid between surface skin cells. This winding route is the dominant path for most applied agents.

Transcellular Pathway Research

Doctoral study examines molecules passing directly through surface skin cells. This route requires crossing successive water and lipid regions.

Follicular Pathway Research

Research examines delivery routed through hair follicles rather than skin. Follicular delivery suits particles and larger delivered molecules.

Partition Coefficient Research

Doctoral work examines how molecules distribute between skin and applied vehicle. Partitioning determines how much agent enters the skin at all.

Diffusion Coefficient Research

Research examines how quickly molecules move within the skin barrier. Diffusion rate combines with partitioning to determine overall delivery.

Permeation Flux Research

Doctoral study examines the quantity crossing skin per unit of area and time. Flux determines whether therapeutic levels can ever be achieved.

Lag Time Research

Research examines the delay before agents appear on the far side of the skin. Lag time affects how quickly any therapeutic effect can begin.

Steady State Permeation

Doctoral work examines the constant delivery rate reached after initial delay. Steady delivery is what sustained patch systems aim to achieve.

Skin Reservoir Research

Research examines agents accumulating within skin rather than passing through. Reservoir behaviour prolongs delivery after removal of the source.

Local Skin Delivery

Research examines confining delivered agents within the skin tissue itself. Local delivery treats skin conditions without whole body exposure.

Regional Delivery Research

Doctoral work examines agents reaching tissues directly beneath the application site. Regional delivery targets muscle and joints below the skin.

Application Site Research

Skin Type Difference Research

Doctoral study examines barrier variation between differing populations and skin types. Reported differences are modest and inconsistently demonstrated.

Sex Difference Research

Research examines whether skin permeability differs between the sexes. Reported differences are small relative to variation between individuals.

Diseased Skin Research

Damaged Skin Research

Research examines delivery through skin whose barrier has been physically compromised. Damaged skin absorbs far more and far less predictably.

Wound Delivery Research

Doctoral study examines applying agents to skin where the surface is broken. Wound application bypasses the barrier and raises infection concerns.

Inflamed Skin Research

Research examines delivery into skin affected by inflammatory conditions. Inflammation changes both barrier function and the local blood flow.

Occlusion Research
