Background: Nanoscale poly (amidoamine) dendrimers have been investigated for their biological demands, but their antibacterial activity has not been widely discovered. Thus, the sixth generation of poly (amidoamine) dendrimer (PAMAM-G6) was synthesized and its antibacterial activities were evaluated on Gram-negative bacteria; P. aeruginosa, E. coli, A. baumannii, S. typhimurium, S. dysenteriae...

Rheumatoid arthritis is a chronic autoimmune disease characterised by joint synovial inflammation, along with cartilage and bone tissue destruction. Dendrimers can offer new opportunities as drug delivery systems of molecules interest. Herein we aimed to develop poly(amidoamine) dendrimers (PAMAM), functionalised chondroitin sulphate (CS), lined anti-TNF α antibodies (Abs) provide anti-inflamma...

PAPER V. Gubala et al. Controlling colloidal stability of silica nanoparticles during bioconjugation reactions with proteins and improving their longer-term stability, handling and storage Despite the potential of antibody-coated nanoparticles (Ab-NPs) in many biological applications, there are very few successful, commercially available examples in which the carefully engineered nanomaterial h...

Highly stable dendrimer-encapsulated Pd nanoparticles in ionic liquids were prepared for the first time by using charged PAMAM dendrimers as templates, which could maintain hydrogenation efficiency for up to at least 12 recycles.

A marked increase of relaxivity has been observed upon rigidifying the internal frame of Gd-containing PAMAM dendrimers: the effect has been attained by either protonation of the dendrimer or by forming supramolecular adducts with cationic polyaminoacids.

The effective life-time of new antimicrobials until the appearance first resistant strains is steadily decreasing, which discourages incentives for commercialization required clinical translation and application. Therefore, development should not only focus on better killing antimicrobial-resistant strains, but as a paradigm shift developing that prevent induction resistance. Heterofunctionaliz...

Diffusion rate of dye-labelled PAMAM dendrimers through free-standing silica colloidal crystals was studied as a function of the dendrimer generation and nanopore size to determine the transport selectivity.
