His work primarily revolves around the modification of hydrophobic polymers and the development of methods for intracellular staining.

Latest Patents

One of A R Azad's latest patents involves the covalent attachment of macromolecules to polysulfones. In this invention, a hydrophobic polymer, such as polysulfone or polyethersulfone, is modified to increase the number of functionalizable chain ends. This is achieved by treating the polymer with an alkali hydroxide to provide hydroxyl groups. A linker is then covalently bonded to a chain end of the polymer, allowing a macromolecule to be covalently bonded to the linker. The macromolecule can be a natural polymer, a synthetic polymer, or a biologically active species. The invention also includes the production of substantially isotropic microporous structures in the form of flat sheets or hollow fibers using a four-component dope composition.

Another significant patent by A R Azad focuses on methods and reagents for staining intracellular components. This patent provides reagents and methods for intracellular staining of anionic materials. The inherent staining characteristics of a fluorescent molecule can be altered by covalently linking multiple fluorescent molecules to a non-immunoglobulin derived cationic polymer. This careful selection enhances diffusion through the cellular membrane and improves the fluorescent signal by localizing multiple fluorescent molecules at the site of interest.
