Incorporation of fluorescent probes into PAMAM dendrimers
Bioelectrochemistry, 2004Interactions of two fluorescent probes 1-(trimethylammoniumphenyl)-6-phenyl-1,3,5 hexatriene p-toluenesulfonate (TMA-DPH) and 12-(9-anthroyloxy) stearic acid (12-AS) with polyamidoamine (PAMAM) dendrimers were studied. Changes in fluorescence intensity and steady-state fluorescence anisotropy of TMA-DPH and 12-AS were monitored. It was found that 12-AS

Synthesis and characterization of immobilized PAMAM dendrons
Chemical Communications, 2007This communication describes the synthesis and characterization of immobilized PAMAM dendrons onto a surface modified silicon wafer substrate (functionalized using plasma polymerized PAA) using a 'growing from' strategy.

Self-assembling of DNA and PAMAM dendrimer
2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005The self-assembling of DNA and cationic polymers are of interest for their biological applications. In this paper, the interaction of DNA with PAMAM was studied by agarose gel electrophoresis, size and zeta-potential measurements and circular dichroism (CD) spectroscopy. DNA was shown to form stable complexes with PAMAM by gel electrophoresis. The mean

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

Towards Fluorescence Sensing Polyamidoamine (PAMAM) Dendritic Architectures.
ChemInform, 2002A novel polyamidoamine (PAMAM) dendrimer (G2.5) 1 with a naphthalene core unit has been prepared and was found to display acid sensitive fluorescence signal amplification making it of potential use as a pH sensor material.

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 ...

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.

DNA Assisted Self-Assembly of PAMAM Dendrimers
The Journal of Physical Chemistry B, 2014We report DNA assisted self-assembly of polyamidoamine (PAMAM) dendrimers using all atom Molecular Dynamics (MD) simulations and present a molecular level picture of a DNA-linked PAMAM dendrimer nanocluster, which was first experimentally reported by Choi et al. (Nano Lett., 2004, 4, 391-397). We have used single stranded DNA (ssDNA) to direct the self-

Bioconjugate Chemistry, 2007
A new convergent synthetic method for the synthesis of PAMAM dendrimers has been developed. The fusion between propargyl-functionalized PAMAM dendrons and azido-functionalized PAMAM dendrons via the Cu(I)-catalyzed Huisgen [2 + 3] dipolar cycloaddition reaction (click chemistry) of an alkyne and an azide leads to the formation of symmetric PAMAM ...
