Bimetallic dendrimer-encapsulated nanoparticles (DENs) are important materials, because they have demonstrated improvement in performance compared to the monometallic DENs in many systems when they are used as catalysts. This tutorial review focuses on the recent research advances in bimetallic DENs with respect to their synthesis, characterization, and applications as catalysts. Bimetallic DEN...

Colorectal cancer (CRC) is the third most frequently occurring tumor in human population. CRCs are usually adenocarcinomatous and originate as a polyp on inner wall of colon or rectum which may become malignant due course time. Although therapeutic options CRC limited, early diagnosis play an important role preventive interventions to decrease mortality rate. The CRC-affected tissues exhibit se...

Cyclodextrin (CyD)-based nanoparticles and polyamidoamine (PAMAM) starburst dendrimers (dendrimers) are used as novel carriers for DNA and RNA. Recently, small interfering RNA (siRNA) complex with β-CyD-containing polycations (CDP) having adamantine-PEG or adamantine-PEG-transferrin underwent a phase I study for treatment of solid tumors. Multifunctional dendrimers can be used for a wide range ...

We report a particle size dependence for the rate of hydrogenation of allyl alcohol using 1.3-1.9 nm Pd dendrimer-encapsulated nanoparticle (DEN) catalysts. For particles with diameters of <1.5 nm and containing <147 Pd atoms, the modulation in catalytic activity is due to the electronic properties of the particle. For the larger particles, 1.5-1.9 nm in diameter and containing an average of 14...

We have designed a new type of a DNA dendrimer which has rigid branched structure. The branching molecule was prepared from 1,3,5-tribromobenzene. The dendrimer unit, in which three oligonucleotide-chains, two molecules of T15 and one molecule of A15, linked to the branching molecule, was synthesized by an automated DNA synthesizer. The properties of the dendrimer unit and dendrimer formation b...

Abstract A Pd-Co bimetallic alloy encapsulated in melamine-based dendrimer supported on magnetic nanoparticles denoted as ?-Fe 2 O 3 @MBD/Pd-Co was synthesized by a facile co-complexation-reduction method and characterized sufficiently. The catalytic evaluation of showed promising results the Mizoroki–Heck Buchwald–Hartwig amination reactions various iodo-, bromo- challenging chloroarenes aqueo...
