Article
Here we report a facile sulfation of TiO2 semiconductor photocatalyst by simply grinding and calcination method using elemental sulfur from desulfurisation of petroleum. The successful sulfation of the prepared visible light active was proved by FT‐IR and XPS measurements, as well. The photocatalytic tests revealed that the S‐TiO2‐2 is the most eff...

In this paper, we firstly demonstrate a simple and reproducible synthesis protocol to produce nicotinamide-stabilized gold nanoclusters (NAM-Au NCs) under mild conditions. The dominant role of the pH and the ligand to metal ion molar ratio on the formation of these few atomic fluorescent NCs were proven. The prepared NCs show intensive blue-emissio...

Introduction: The present work describes a calorimetry-founded characterization and design of a potential surfactant based colloidal drug delivery system. However, numerous research groups have published their outcomes according to the thermodynamic characterization of mixed micelle formation but only a few articles provide deeper information on th...
Article
We first demonstrate a simple and rapid fabrication protocol of bovine serum albumin (BSA) nanoparticles (NPs), as potential drug carriers using a microchannel flow technique with the successful encapsulation of a water-soluble kynurenic acid (KYNA) having neuroactive property has also been performed. By comparison, the preparation of a hydrophobic...

Project
The use of colloidal delivery systems, such as nanoparticles and associated colloids, has drawn a particular attention in the clinical therapy. These nanosized carriers can also be manipulated to guide the drugs toward desired cells and improve the biodistribution. Formulation and physicochemical properties of these solid and semi-solid particles play an important role in bioavailability and targeting efficiency of drugs.
Project
One of the main aims of the research program is the development of new eco-friendly synthetic routes that produce noble metal nanoclusters having size- and composition-dependent fluorescence. In addition to the structural analysis of the fluorescent systems, the stability, as well as the biocompatibility measurements of the sub-nanometer-sized particles are also investigated. Within the framework of the biomedical applications of the noble metal nanoclusters, the diagnostic possibilities, and the sensor measurements are decisively highlighted.
Project
The general objective of the project is to investigate the interactions between physiologically important receptors (peptides or model peptide fragments) and potential drug molecules by using quasi-two-dimensional sensing techniques (QCM, OWLS, SPR). Usually, the modelling of sensorgrams was carried out by using several commercial softwares, but in contrast with these evaluation procedures we provided the kinetic and thermodynamic data of this model receptor-ligand system via a self-developed method. During spreadsheet-based data processing we utilize the concentration dependent sensorgrams in order to give kinetic parameters of the above mentioned interaction. While based on the temperature dependence of kinetic parameters the thermodynamic state functions become determinative.
