Abstract
Nanomedicine is an emerging area that largely influences the efficacy of various therapies through the rational design of new materials exhibiting more targeted behavior. The synthetic effort, the amount of used material, and the cost are critical parameters to bear in mind if the production of the designed material is intended to be scaled for their widespread use. Even though materials science offers diverse options for different types of therapies, it is a difficult task to meet all the parameters mentioned above. The dendronization appears as an insightful approach to incorporate all the known benefits of the dendritic architecture by the attachment of dendrons to therapeutic agents, but in a much more affordable manner in terms of synthetic effort, amount of material, and cost. As will be presented, the most common dendrons used for biomedical applications are polyamide, polyester, carbosilane, polyether, and glycol-type, which are bonded to biological active molecules (BAMs), or molecular nanoplatforms (MPs) by hydrolysable bonds. Also relevant is the fact that the incorporation of dendrons not larger than third generation (G3) is sufficient to improve essential properties of these molecular systems, such as aqueous solubility, stability, and cellular internalization, among others. The type of dendron and its location on the BAMs or MPs, similar to placing a Lego piece on a model, will be decisive for obtaining the desired properties.

Abstract
New amphiphilic carbosilane dendrons with pH-dependent behaviour based on the presence of carboxylate (propionate or succinate) groups at their peripheries and a fatty acid at the focal point were developed. In the presence of salts, they were able to form micelles with critical aggregation concentrations increasing with increasing dendron generation. Their thermodynamic parameters were calculated from surface tension measurements and their diameters at different pHs were measured by dynamic light scattering. These micelles were stable at basic pH but degraded under acidic conditions. No significant differences were found for the propionate and succinate based dendron micelles at basic or acidic pH, but the succinate dendron assemblies were more stable at neutral pH. The properties of these systems as drug nano-carriers were studied using both hydrophilic and hydrophobic molecules, and the drug loading varied with the structure and charge of the drug. In addition, due to the presence of multiple negative charges, the dendrons exhibited anti-HIV activity. Higher generation dendrons with more peripheral carboxylates that were not assembled into micelles were more active than micelles composed of lower generation dendrons having fewer peripheral carboxylates.

Abstract
The anionic carbosilane (CBS) dendrimer with sulfonate groups G2-S16 is a promising compound for the preparation of a microbicide gel to prevent HIV infection. However, until now its synthesis required aggressive conditions. Hence, a reliable synthetic procedure is very important to face GMP conditions and clinical trials. In this study, G2-S16 has been prepared by a new approach that involves the addition of an amine-terminated dendrimer to ethenesulfonyl fluoride (C2H3SO3F, ESF) and then transformation to the sulfonate dendrimer by treatment with a base. This strategy also makes feasible the synthesis of a labelled sulfonate dendrimer (G2-S16-FITC) to be used as a molecular probe for in vivo experiments. Interestingly, G2-S16-FITC enters into human peripheral blood mononuclear cells (PBMCs). Ethenesulfonyl fluoride (ESF) is a useful reagent to prepare sulfonate carbosilane dendrimers with antiviral properties and labelled dendrimers for biological studies.![]()

Abstract
Heterofunctionalized gold nanoparticles (AuNPs) were obtained in a one pot reaction of gold precursor with cationic carbosilane dendrons (first to third generations, 1-3G) and (polyethylene)glycol (PEG) ligands in the presence of a reducing agent. The final dendron/PEG proportion on AuNPs depends on the initial dendron/PEG ratio (3/1, 1/1, 1/3) and dendron generation. AuNPs were characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS), ultraviolet spectroscopy (UV-VIS), thermogravimetric analysis (TGA), nuclear magnetic resonance (1H NMR) and zeta potential (ZP). Several assays have been carried out to determine the relevance of PEG/dendron ratio and dendron generation in the biomedical properties of PEGylated AuNPs and the results have been compared with those obtained for non-PEGylated AuNPs. Finally, analyses of PEG recognition by anti-PEG antibodies were carried out. In general, haemolysis, platelet aggregation and toxicity were reduced after PEGylation of AuNPs, the effect being dependent on dendron generation and dendron/PEG ratio. Dendron generation determines the exposure of PEG ligand and the interaction of this ligand with AuNPs environment. On the other hand, increasing PEG proportion diminishes toxicity but also favors interaction with antibodies.

Abstract
Newly synthesized carbosilane copper dendrimers (CCD) with chloride and nitrate surface groups seem to be good candidates to be used as gene and drug carriers in anti-cancer therapy, due to their properties such as size and surface charge. Copper attached to the nanoparticles is an important element of many biological processes and recently their anti-cancer properties have been widely examined. Zeta size and potential, transmission electron microscopy (TEM), circular dichroism (CD), analysis of haemolytic activity, and fluorescence anisotropy techniques were used to characterize copper dendrimers. Additionally, their cytotoxic properties toward normal (PBMC) and cancer (1301; HL-60) cells were examined. All tested dendrimers were more cytotoxic against cancer cells in comparison with normal cells.

Abstract
The interaction of neuropeptides, vasoactive intestinal peptide (VIP), or growth hormone-releasing hormone (GHRH), with a cationic carbosilane dendrimer forms dendriplexes with antitumoral behavior in advanced prostate cancer cells PC3. At the concentrations used for dendriplexes formation, the free peptides were protumoral and prometastatic in advanced prostate cancer, while dendrimer only showed low cytotoxicity, but did not avoid the metastatic behavior of PC3 cells. However, these nanoplexes favored also cell adhesion and avoided cell migration. Also, the dendriplexes were not toxic for no tumoral prostate cells (RPWE-1) or fibroblasts. The use of labeled GHRH peptide (rhodamine labeled) and a dendrimer (fluorescein labeled) allowed us to observe that both systems reach the intracellular milieu after dendriplex formation. The treatment of PC3 cells with the nanoplexes reduced expression of vascular endothelial growth factor (VEGF) and cyclic adenosine monophosphate (cAMP). Molecular modeling analysis highlights the important contribution of the carbosilane framework in the stabilization of the dendriplex, since dendrimer interacts with a peptide region where hydrophobic amino acids are presented.

Abstract
Gold nanoparticles (AuNPs) and polycationic macromolecules are used as gene carriers. Their behaviour is dependent on several factors, such as the size and type of the framework, charge, etc. We have combined both types of systems and prepared AuNPs covered with cationic carbosilane dendrons with the aim to evaluate their biocompatibility. Water soluble dendronized cationic AuNPs were prepared following a straightforward procedure from dendrons, a gold precursor and a reducing agent in water and were characterized by 1H NMR, transmission electron microscopy (TEM), dynamic light scattering (DLS), thermogravimetric analysis (TGA), ultraviolet spectroscopy (UV), and zeta potential (ZP). The biological properties of dendrons and AuNPs were determined by hemolysis, platelet aggregation and lymphocyte proliferation. These assays reflect modification of dendron properties when covering nanoparticles. For dendrons, hemolysis and platelet aggregation are generation dependent whilst, for AuNPs these properties are related to the bigger size of NPs. On the other hand, none of the systems induced lymphocyte proliferation. Selected cationic dendrons and AuNPs were chosen for gene delivery experiments employing a small interference RNA (siRNA Nef) against human immunodeficiency virus (HIV).

Abstract
By integrating imaging and drug-delivery in a single system, fluorescent nano-multifunctional imaging platforms can offer simultaneous diagnosis and therapy to diseases like cancer. However, the synthesis of such system involves a tedious, time-consuming, and multi-step process. Herein we report a facile method based on simple ultrasonication to synthesize highly cross-linked, monodispersed fluorescent polyphosphazene nanoparticles from hexachlorocyclotriphosphazene (HCCP) and dichlorofluorescein (FD). Various functional groups (folic acid, PEG-NH2, and methylene blue) can be "fastened" in situ onto the poly(cyclotriphosphazene-co-dichlorofluorescein) (PCTPDF) nanoparticles to expand its application as nano-multifunctional platform. All the nanoparticles were characterized spectrophotometrically, and morphology was established by the images obtained from scanning electron microscope (SEM). The synthesized multifunctional nanoparticles exhibited low toxicity and penetrated through the cytomembranes of human colon cancer (HCT 116) cells. When applied to in vivo tumor imaging using biologically engineered mouse model, methylene blue functionalized (PCTPDF@MB) nanoparticles exhibited excellent photodynamic activity and imaging ability. Thus, PCTPDF nanoplatform based on multi-functional fluorescent nanoparticles might offer an efficient solution to new age theranostics. Apart from diagnostics application, PCTPDF, as a nanoplatform, could also be utilized to achieve more comprehensive application in modern analytic chemistry. Graphical Abstract The table of contents.

Abstract
Water soluble silver nanoparticles (AgNPs) capped with cationic carbosilane dendrons have been synthesized by direct reaction in water of dendrons, silver precursor and a reducing agent. These nanoparticles have been characterized by nuclear magnetic resonance (NMR), transmission electron microscopy (TEM), dynamic light scattering (DLS), thermogravimetric analysis (TGA), ultraviolet spectroscopy (UV), elemental analysis, and zeta potential (ZP). The antibacterial and antifungal properties of the cationic dendrons and dendronized AgNPs and AuNPs with these dendrons have been evaluated against Gram-negative and Gram-positive bacterial -including resistant strains- and yeast strains, respectively. The results stand out for the activity of AgNPs covered with first generation dendron compared with this free dendron and corresponding dendronized AuNPs.

Abstract
Anionic carbosilane dendrons decorated with sulfonate functions and one thiol moiety at the focal point have been used to synthesize water-soluble gold nanoparticles (AuNPs) through the direct reaction of dendrons, gold precursor, and reducing agent in water, and also through a place-exchange reaction. These nanoparticles have been characterized by NMR spectroscopy, TEM, thermogravimetric analysis, X-ray photoelectron spectroscopy (XPS), UV/Vis spectroscopy, elemental analysis, and zeta-potential measurements. The interacting ability of the anionic sulfonate functions was investigated by EPR spectroscopy with copper(II) as a probe. Different structures and conformations of the AuNPs modulate the availability of sulfonate and thiol groups for complexation by copper(II). Toxicity assays of AuNPs showed that those produced through direct reaction were less toxic than those obtained by ligand exchange. Inhibition of HIV-1 infection was higher in the case of dendronized AuNPs than in dendrons.
