Fluorescence Analysis Of PAMAM Dendrimers
2023Despite their lack of conjugation, polyamidoamine (PAMAM) dendrimers are intrinsically fluorescent, and this fluorescent is somewhat manipulable through altering the dendrimer's solvent. This level of fluorescence is dependent on a number of the dendrimer's qualities: the pH of the solvent, the mass percent concentration of the dendrimer in solvent ...

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.

Antioxidant Action by Gold−PAMAM Dendrimer Nanocomposites
Langmuir, 2004Gold-dendrimer nanocomposites were prepared in the presence of poly(amidoamine) (PAMAM) dendrimer (generation 3, 3.5, 5, and 5.5) via reduction of HAuCl4 with sodium borohydride. The average particle size of the gold nanoparticles was independent of the dendrimer concentration, ranging between 3.0 and 4.3 nm in diameter. The catalytic activities of the

Convergent Synthesis of Internally Branched PAMAM Dendrimers
Organic Letters, 2005[reaction: see text] A series of aliphatic internally branched poly(amido amine) dendrons and dendrimers has been synthesized. The internal branching unit was 1,2-propanediamine and a series of PAMAM-type dendrons of the types AB2, AB4, and AB8 were built.

PAMAM dendrimers: A multifunctional nanomaterial for ECL biosensors
Talanta, 2017Polyamido amine (PAMAM) dendrimers have been shown to function as electrochemiluminescence (ECL) co-reactant and have the inherent capability of improving immobilization of molecules on surfaces due to their dendritic structure. Here, we investigated the combination of both of these properties as the basis for biosensor development.

PAMAM Dendrimers as Delivery Agents for Antisense Oligonucleotides
Pharmaceutical Research, 1999To investigate the potential use of PAMAM dendrimers for the delivery of antisense oligonucleotides into cells under conditions that mimic the in vivo environment.We used HeLa cells stably transfected with plasmid pLuc/705 which has a luciferase gene interrupted by a human beta-globin intron mutated at nucleotide 705, thus causing incorrect splicing ...
