Species Transport

Veryst assists clients in addressing problems involving transport of chemical substances.  Our experience in species transport includes transdermal drug delivery and permeability of polymer systems.  We employ advanced computational methods to model the complex coupled interactions between solute concentrations and carrier material properties, applying appropriate simplifications for cases involving low concentration species transport.  We also develop specialized algorithms for advection-dominated mass transfer problems with very high Péclet numbers.  Our clients have used our analyses of their existing products both to understand performance and develop improvements, which in some instances has resulted in new intellectual property.

Transdermal Drug Delivery

Veryst developed a diffusion model accounting for the different layers of the human skin in order to predict the drug concentration profile of a transdermal drug delivery process.

Transdermal Permeation Enhancers

Permeation enhancers are used to improve drug delivery through the skin by altering the structure and dynamics of the skin. Veryst developed a finite element model of drug diffusion from an adhesive patch that accounts for the effect of permeation enhancers.
