G4-OH was modified with linker having minimal amine groups and incorporation of TA as a nuclear localization enhancer resulted in compact gene vectors with favorable safety profile and achieved high levels of transgene expression in hard to transfect human retinal pigment epithelial cells (hRPE). Prepared dendrimer-gene complexes were non-toxic and achieved significant cell uptake and safe delivery of gene in to the nucleus. Further, polyethylene glycol (PEG) surface coating enhanced colloidal stability in physiological relevant solutions without affecting its transfection efficacy.

The treatment of ocular diseases poses a significant challenge to drug delivery design, due to the eye's complex anatomy, with a semi-permeable blood-ocular barrier and associated immune privilege. To address some of the delivery challenges, polycationic dendrimers are explored as vehicle for the treatment of posterior chamber disease. Dendrimers are a class of polymeric nanoparticles that are highly branched, multivalent and monodisperse, whose three-dimensional globular architecture has given them the nickname of "synthetic proteins". Dendrimers are synthesized by reacting monomers in a step-wise fashion to produce generationally and radially increasing structures, with core, interior and surface chains that are highly customizable. Polyamidoamine (PAMAM) dendrimers, in particular, have been studied for a wide range of biomedical applications. The high drug loading capacity, by physical encapsulation and chemical conjugation with dendrimer surface groups, over a small hydrodynamic range (diameter d"4 nm) enables their usefulness in nanoparticle form and as building blocks for macro-structures. This dissertation explores the utilization of amine-terminated ( -NH2) PAMAM dendrimers as static or dynamic nanoparticle and hydrogel drug and gene carriers. These formulations are evaluated for their enhancement of the delivered therapeutic bioavailability and prolonged activity from extended release platforms to treat head and neck cancers and retinoblastoma

The dendrimer is a common name of polymers which are characterised by a specific structure, although their chemical composition can be very different. Dendrimers display several characteristics which distinguish them from linear polymers. All dendrimers are synthesised by attaching branched monomers to the central core molecule. Monomers are attached layer by layer. As a result of such a synthesis, dendrimers posses plenty of terminal, reactive groups on their surface and empty internal cavities. Both of these features can be utilised. Soon after the first synthesis in mid-1980's, dendrimers have become interesting and promising molecules for pharmaceutical and technical aims. The last years brought many new facts about dendrimers impact on biological systems. Both, general toxic studies, as well as detailed research devoted to particular cellular compounds, as DNA or lipid bilayer, were carried out. New types of dendrimers were synthesised and new applications appeared.
