Research interests
Enhanced delivery of therapeutic macromolecules to the skin via microfabricated microneedles
The skin epidermis represents an appropriate target for the delivery of low molecular weight drugs, vaccines, biopharmaceuticals and gene based therapies. The skin, however, is characterised by poor permeability. Microfabricated microneedle arrays are designed to pierce the stratum corneum skin barrier layer in a minimally invasive and pain-free manner to provide transient pathways for the delivery of macromolecules to the underlying skin epidermis.
Delivery of formations via pulmonary routes
Although non-viral gene vectors are capable of mediating gene transfer both in vitro and in vivo following nebulisation, the delivery efficiency of conventional nebuliser systems is greatly reduced due to the restrictions of the device and the physico-chemical characteristics of the particles at elevated concentrations in the nebuliser reservoir. While newer nebuliser technologies are under development, pressurised metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs) may provide more viable alternatives for delivering therapeutically active macromolecules, particularly genes, to the lung.
