Recently, self-assembling small dendrimers into supramolecular dendritic systems offers an alternative strategy to develop multifunctional nanoplatforms for biomedical applications. We herein report a dual-responsive supramolecular PEGylated dendritic system for efficient platinum-based drug delivery and near-infrared (NIR) tracking. With a refined molecular/supramolecular engineering, supramol...
Nanotechnology is an emerging research field that helps in reviving the structural design, synthesis and fabrication at the molecular magnitude. There are approximately 130 nanopharmaceutical products in development including~nanoparticles, nanocrystals, dendrimers, liposomes and micelles. The increase in the selectivity and stability of therapeutic agents can be achieved with the help of Nanop...
Major attention has been focused on dendrimer-DNA complexes because of their applications in gene delivery systems. Dendrimers are also used to transport miRNA and siRNA in vitro. We examine the interaction of tRNA with several dendrimers of different compositions, mPEG-PAMAM (G3), mPEG-PAMAM (G4), and PAMAM (G4) under physiological conditions using constant tRNA concentration and various dendr...
We report a new use of dendrimer-entrapped gold nanoparticles (Au DENPs) modified by polyethylene glycol (PEG) with good biocompatibility for in vitro and in vivo imaging of atherosclerotic mice by computed tomography (CT). In this study, Au DENPs were synthesized using poly(amidoamine) (PAMAM) dendrimers of generation 5 (G5.NH2) modified by PEG monomethyl ether (G5.NH2-mPEG20) as templates. In...
Nano-oncology is a branch of biomedical research and engineering that focuses on using nanotechnology in cancer diagnosis treatment. Nanomaterials are extensively employed the field oncology because their minute size ultra-specificity. A wide range nanocarriers, such as dendrimers, micelles, PEGylated liposomes, polymeric nanoparticles used to facilitate efficient transport anti-cancer drugs at...
The current study sought to explore whether the subcutaneous administration of lymph targeted dendrimers, conjugated with a model chemotherapeutic (methotrexate, MTX), was able to enhance anticancer activity against lymph node metastases. The lymphatic pharmacokinetics and antitumor activity of PEGylated polylysine dendrimers conjugated to MTX [D-MTX(OH)] via a tumor-labile hexapeptide linker w...
