The mechanisms of drug release in poly(lactic-co-glycolic acid)-based drug delivery systems--a review.
Poly(D,L-lactic-co-glycolic acid) (PLGA) is the most frequently used biodegradable polymer in the controlled release of encapsulated drugs. Understanding the release mechanisms, as well as which… Expand

Mechanistic modelling of drug release from polymer-coated and swelling and dissolving polymer matrix systems.
The time required for the design of a new delivery device can be sensibly reduced if the release mechanism is understood and an appropriate mathematical model is used to characterize the system. Once… Expand

Effect of hindered diffusion on the adsorption of proteins in agarose gel using a pore model.
The hindered diffusion and binding of proteins of different sizes (lysozyme, BSA and IgG) in an agarose gel is described using adsorption kinetic and diffusional data together with an experimentally… Expand

Model-based optimization of a preparative ion-exchange step for antibody purification.
A method using a model-based approach to design and optimize an ion-exchange step in a protein purification process is proposed for the separation of IgG from a mixture containing IgG, BSA and… Expand
