Reversible pH-sensitive chitosan-based hydrogels. Influence of dispersion composition on rheological properties and sustained drug delivery
(MDPI, 2018)
The present work deals with the synthesis of micro-structured biomaterials based on chitosan (CTS) for their applications as biocompatible carriers of drugs and bioactive compounds. Twelve dispersions were prepared by ...

Solving the Hydration Structure of the Heaviest Actinide Aqua IonKnown: The Californium(III) Case
(Wiley-Blackwell, 2010)
Wish they all could be californium: X-ray absorption spectroscopy (black points) and Monte Carlo simulations (blue line) of Cf" in aqueous solutions have been combined to determine the ligand distance and coordination ...

Tandem ATRP/Diels-Alder Synthesis of PolyHEMA-based Hydrogels
(Royal Society of Chemistry, 2014)
The efficient, controlled polymerization of a batch of new poly(hydroxyethyl methacrylate-co-furfuryl methacrylate)s, [poly(HEMA-co-FMA)], of various compositions was achieved using atom transfer radical polymerization ...

Preparation of water-soluble glycopolymers derived from five-membered iminosugars
(Elsevier, 2019-10)
Iminosugars are carbohydrate mimetics that constitute the main group of oligosaccharide processing enzyme inhibitors. They play an important role in cell-cell recognition processes, thereby presenting a wide range ...

Nanocomposites of Microbial Polyglutamic Acid and Nanoclays Compatibilized by Organophosphonium Surfactants
(Wiley, 2018)
Ionic coupling of bacterial poly(γ-glutamic acid) (PGGA) with alkyltrimethylphosphonium surfactants is reported to render comb-like PGGA complexes with a biphasic-layered structure displaying periodicity at the nanoscopic ...

pH-Responsive Polymeric Nanoparticles as Drug Delivery Systems
(JSciMed Central, 2017-04)
Micelles are excellent devices to be used as controlled drug delivery systems since they exhibit the ability to protect the drug or encapsulated substance from the routes of degradation until they reach the site of action: ...

Collecting high-order interactions in an effective pairwise intermolecular potential using the hydrated ion concept: The hydration of Cf3+
(American Institute of Physics Publising LLC, 2014)
This work proposes a new methodology to build interaction potentials between a highly charged metal cation and water molecules. These potentials, which can be used in classical computer simu- lations, have been fitted to ...

Glucose-nucleobase pairs within DNA: Impact of hydrophobicity, alternative linking unit and DNA polymerase nucleotide insertion studies
(Royal Society of Chemistry, 2018)
Recently, we studied glucose-nucleobase pairs, a binding motif found in aminoglycoside-RNA recognition. DNA duplexes with glucose as a nucleobase were able to hybridize and were selective for purines. They were less stable ...

Validation of Smart Nanoparticles as Controlled Drug Delivery Systems: Loading and pH-Dependent Release of Pilocarpine
(American Chemical Society, 2018-01-11)
Micelles are good devices for use as controlled drug delivery systems because they exhibit the ability to protect the encapsulated substance from the routes of degradation until they reach the site of action. The ...
