General description

Dendrimers and dendrons are symmetrically branched polymer structures that possess a well-defined spatial distribution of functional groups. Dendrimers are chemically modified by attaching poly ethylene glycol (PEG) molecule to increase its solubility and prolong circulation half-life.“Clickable groups”, such as primary acetylenes, are introduced to the mono dispersed dendritic structures, using “click” chemistry. These acetylene groups, attached to Bis-MPA based dendrons, allow it to form the conjugates with bioactive moieties such as carbohydrate, fluorescent dyes, disaccharides etc.


The proposed uses are
• as an efficient drug delivery system.
• In vitro toxicological studies
• In vivo via radionuclide labeling and optical imaging
• Biosensors
• Dip pen nanolithography
