Fluorescence emission from PAMAM and PPI dendrimers
Journal of Colloid and Interface Science, 2007A strong fluorescence emission from poly(amido amine) (PAMAM) dendrimers with different terminal groups or a poly(propylene imine) (PPI) dendrimer was studied under different conditions by varying experimental parameters such as pH value, aging time, temperature, and concentration.

Nanoscale Protein Pores Modified with PAMAM Dendrimers
Journal of the American Chemical Society, 2007We describe nanoscale protein pores modified with a single hyperbranched dendrimer molecule inside the channel lumen. Sulfhydryl-reactive polyamido amine (PAMAM) dendrimers of generations 2, 3 and 5 were synthesized, chemically characterized, and reacted with engineered cysteine residues in the transmembrane pore alpha-hemolysin.

CuO nanoparticles with PAMAM dendrimers
Journal of Coordination Chemistry, 2016AbstractAn easy pathway to synthesize a variety of cupric oxide (CuO) nanoshapes by a one-step wet chemical method is reported. CuO nanoparticles and nanorods were obtained from CuCl2 in a mixture of water and DMSO in the absence of a base at room temperature.

Penicillin V-conjugated PEG-PAMAM star polymers
Journal of Biomaterials Science, Polymer Edition, 2003Starburst PAMAM dendrimers are potential carriers for drug delivery due to their unique structure. Drug-delivery scaffolds were designed and built up based on the polyethylene glycolpolyamidoamine (PEG-PAMAM) star polymer. Penicillin V was used as a model carboxylic group containing drug to conjugate with full- and half-generation PAMAM dendrimers.

Toxicity of PAMAM dendrimers to Chlamydomonas reinhardtii
Aquatic Toxicology, 2010In recent decades, a new class of polymeric materials, PAMAM dendrimers, has attracted marked interest owing to their unique nanoscopic architecture and their hopeful perspectives in nanomedicine and therapeutics. However, the potential release of dendrimers into the aquatic environment raises the issue about their toxicity on aquatic organisms.

DNA-Templated Covalent Coupling of G4 PAMAM Dendrimers
Journal of the American Chemical Society, 2010Generation-4 polyamidoamine (PAMAM) dendrimers were surface-functionalized with azides or alkynes and conjugated to one DNA strand. DNA-controlled self-assembly of alternating azide and alkyne dendrimers on a DNA template enabled the coupling of the dendrimers by the azide-alkyne "click" reaction to form covalently coupled dimers, trimers, and ...

Synthesis of aromatic hyperbranched PAMAM polymers
Tetrahedron Letters, 2004Abstract Our preliminary results towards the synthesis of hyperbranched polyamidoamine (PAMAM) polymers as ‘dendrimer equivalents’ is described. An aromatic AB2 bis-amino acid monomer was polymerised at 165 °C (under vacuum) and the crude mixture purified by dialysis.
