Abstract In spite of the fact that cadmium(II) has been recognized as a highly toxic element and excessive exposure to this metal ion reported have many adverse effects on human health, very few selective specific fluorescent probes are available for imaging Cd 2+ in living cells. Herein, we report spectroscopic photochemical characterization 5‐(5‐chloro‐8‐hydroxyquinolinylmethyl)‐2,8‐dithia‐5‐aza‐2,6‐pyridinophane ( L ) sensor particular, response was first assessed aqueous solutions,...
In this work, monoolein-based cubosomes were doped with two fluorescent probes, namely, fluorescein and dansyl, properly modified a hydrocarbon chain to increase their encapsulation efficiency within the monoolein palisade. The same nanocarriers also loaded quercetin, hydrophobic molecule potential anticancer activity. Particularly, probe successfully exploited for single living cell imaging. physicochemical photophysical characterizations reported here, along well-known ability of in...
This work was devoted to the development of a new type lipid-based (cubosome) theranostic nanoparticle able simultaneously host camptothecin, potent anticancer drug, and squarain-based NIR-emitting fluorescent probe. Furthermore, confer targeting abilities on these nanoparticles, they were dispersed using mixtures Pluronic F108 folate-conjugated in appropriate ratios. The physicochemical characterization, performed via SAXS, DLS, cryo-TEM techniques, proved that aqueous dispersions such...
This review covers various aspects of recent developments on the design, synthesis, characterization gels that: (i) are formed in presence metal ions (metallogels); (ii) based coordination complexes as gelators. Particular attention is devoted to systems that show recognition and sensing properties towards different analytes.
The macrocycles L1−L3 incorporating N2S3-, N2S2O-, and N2S2-donor sets, respectively, containing the 1,10-phenanthroline unit interact in acetonitrile solution with heavy metal ions such as PbII, CdII, HgII to give 1:1 ML, 1:2 ML2, 2:1 M2L complex species, which specifically modulate photochemical properties of ligands. stoichiometry species formed during spectrofluorometric titrations their formation constants MeCN at 25 °C were determined from fluorescence vs MII/L molar ratio data....
The chemical bond and structural features for the most important classes of solid products obtained by reacting chalcogen donors with dihalogens interhalogens are reviewed. Particular attention is paid to information FT-Raman spectroscopy can confidently give about each motif considered in absence X-ray analyses.
Here, we describe a novel monoolein-based cubosome formulation engineered for possible theranostic applications in oncology. The Docetaxel-loaded nanoparticles were stabilized water by mixture of commercial Pluronic (poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) triblock copolymer) F108 (PF108) and rhodamine- folate-conjugated PF108 so that the possess targeting, therapeutic, imaging properties. Nanoparticles investigated DLS, cryo-TEM, SAXS to confirm their structural...
Nine dioxidomolybdenum(VI) complexes were synthesized through the reactions of MoO 3 with tridentate hydrazone Schiff base ligands obtained from aromatic acid hydrazides (3‐hydroxy‐2‐naphthoic hydrazide, 4‐pyridinecarboxylic hydrazide and 2‐furoic hydrazide) ortho ‐hydroxy aldehyde derivatives (5‐iodo‐2‐hydroxybenzaldehyde, 2‐hydroxy‐1‐naphthaldehyde 2‐hydroxy‐3‐methoxybenzaldehyde). All characterized by elemental analysis spectroscopic methods. The structures seven further elucidated...

FT-Raman spectra of some polyiodides and a series D · I 2 charge-transfer complexes (where is molecule containing the thione or selone groups as donors), all characterized by x-ray diffraction, are reported. For adducts with compounds, which can be considered weak medium-weak complexes, an empirical linear correlation between frequency v(I-I) stretching vibrations d(I-I) bond distances has been found. Some show that indistinguishable respect to those displayed neutral strength; in such...
