Dendrimer mediated clustering of bacteria: improved aggregation and evaluation of bacterial response and viability
(Royal Society of Chemistry, 2016)Here, we evaluate how cationic gallic acid-triethylene glycol (GATG) dendrimers interact with bacteria and their potential to develop new antimicrobials. We demonstrate that GATG dendrimers functionalised with primary ... -
Dendrimers as Color-Stabilizers of Pyranoanthocyanins: the Dye Concentration Governs the Host-Guest Interaction Mechanisms
(ACS, 2021)Anionic dendrimers have recently emerged as hosts (H) for the color stabilization of the flavylium cation of anthocyanin guests (G). The interaction with a promising, more hydrophobic pyranoanthocyanin illustrates how the ... -
Dendrimers as Innovative Radiopharmaceuticals in Cancer Radionanotherapy
(American Chemical Society, 2016)Radiotherapy is one of the most commonly used cancer treatments, with an estimate of 40% success that could be improved further if more efficient targeting and retention of radiation at the tumor site were achieved. This ... -
Dendrimers reduce toxicity of Aβ 1-28 peptide during aggregation and accelerate fibril formation
(Elsevier, 2012-11)The influence of a GATG (gallic acid-triethylene glycol) dendrimer decorated with 27 terminal morpholine groups ([G3]-Mor) on the aggregation process of Alzheimer's peptide has been investigated. Amyloid fibrils were formed ... -
A dendrimer–hydrophobic interaction synergy improves the stability of polyion complex micelles
(Royal Society of Chemistry, 2017-03-28)Polyion complex (PIC) micelles incorporating PEG-dendritic copolymers display an unprecedented stability towards ionic strength that is amplified via hydrophobic interactions. The tridimensional orientation of peripheral ... -
A designed DNA binding motif that recognizes extended sites and spans two adjacent major grooves
(Royal Society of Chemistry, 2016-02-05)We report the rational design of a DNA-binding peptide construct composed of the DNA-contacting regions of two transcription factors (GCN4 and GAGA) linked through an AT-hook DNA anchor. The resulting chimera, which ... -

Designing Irreversible Inhibitors—Worth the Effort?
(Wiley, 2016-01-07)Despite the unquestionable success of numerous irreversible drugs that are currently in clinical use, such as acetylsalicylic acid (Aspirin) and penicillin, the number of such approved drugs is much lower than that of ... -
Detection of degradation markers from polymer surfaces by a novel SERS-based strategy
(Elsevier, 2019)This paper provides new insights for the study of polymer degradation through the detection of markers released at the polymer surface using Al-coated SERS active substrates. Combining a nanodestructive sampling procedure ... -
Detection of phosphorylation states by intermolecular sensitization of lanthanide–peptide conjugates
(Royal Society of Chemistry, 2012)The luminescence of a designed peptide equipped with a coordinatively-unsaturated lanthanide complex is modulated by the phosphorylation state of a serine residue in the sequence. While the phosphorylated state is weakly ... -
Development of fluorescent probes that target serotonin 5-HT2B receptors
(Nature Publishing Group, 2017)Some 5-HT2B fluorescent probes were obtained by tagging 1-(2,5-dimethoxy-4-iodophenyl)-propan2-amine (DOI) with a subset of fluorescent amines. Some of the resulting fluorescent ligands showed excellent affinity and ... -
DFT and Kinetic Monte Carlo Study of TMS-Substituted Ruthenium Vinyl Carbenes: Key Intermediates for Stereoselective Cyclizations
(American Chemical Society, 2015)Mechanistic pathways for the cyclization of 1,5-alkynylacetal with N2CHTMS in the presence of Cp- and Cp*RuCl(cod) to afford Z and E (trimethylsilyl)vinyl spiroacetals have been calculated. Calculations show the presence ... -
Different intracellular distribution of avian reovirus core protein sigmaA in cells of avian and mammalian origin
(Elsevier, 2012)A comparative analysis of the intracellular distribution of avian reovirus (ARV) core protein sigmaA in cells of avian and mammalian origin revealed that, whereas the viral protein accumulates in the cytoplasm and nucleolus ... -
Different-Length Hydrazone Activated Polymers for Plasmid DNA Condensation and Cellular Transfection
(American Chemical Society, 2018)The recent advances in genetic engineering demand the development of conceptually new methods to prepare and identify efficient vectors for the intracellular delivery of different nucleotide payloads ranging from short ... -
Dihydrobiphenylenes through Ruthenium‐Catalyzed [2+2+2] Cycloadditions of ortho‐Alkenylarylacetylenes with Alkynes
(Wiley, 2014)A new synthetic route to dihydrobiphenylenes has been developed. The process involves a mild RuII‐catalyzed [2+2+2] dimerization of ortho‐alkenylarylacetylenes or its more versatile variant, the Ru‐catalyzed [2+2+2] ... -
Direct protein quantification in complex sample solutions by surface-engineered nanorod probes
(Springer Nature, 2017)Detecting biomarkers from complex sample solutions is the key objective of molecular diagnostics. Being able to do so in a simple approach that does not require laborious sample preparation, sophisticated equipment and ... -
Directed self-assembly of trimeric DNA-bindingchiral miniprotein helicates
