Synthesis of novel and unique PAMAM (poly-amidoamine) polymers. PAMAM polymers can be grown by systematic alternation between ethylenediamine (EDA) and methacrylate. By taking advantage of the alternating terminal ends, successive generations G1 and G0.5 were combined under acidic conditions with Pluronic P123 as a liquid-crystal template. The resulting polymer was imaged with TEM and the product was circular and amorphous of no characteristic size ranging between about 5 nm to about 600 nm, with remarkable electrochemical activity unseen in any of the generations of PAMAM. Applications of this electroactive poly-amidoamine organic polymer include use as a new electron transfer reagent for amperometric biosensors.

Reaction products of primary and secondary diamines and bisanhydrides are included as additives in metal electroplating baths. The metal electroplating baths have good throwing power and deposit metal layers having substantially planar surfaces. The metal plating baths may be used to deposit metal on substrates with surface features such as through-holes and vias.
