Abstract:
We report the optimal conditions for the separation of spermidine from different types of samples, for example blood or cancer cells and its subsequent determination by ion-exchange liquid chromatography (IEC) with UV-VIS detector. Here in, we synthesized paramagnetic particles able to isolate and immobilize spermidine from blood of patients with cancer or cancer cells and thus preconcentrate it for analysis. [..]

Abstract:
In this paper, we report the optimal conditions for the isolation and preconcentration of branched chain amino acids (BCAAs) – leucine, valine and arginine from different types of matrix, such as tissue, plasma, blood, bacteria or cells. Herein, we focused on the synthesis of paramagnetic particles able to isolate and immobilize amino acids and thus preconcentrate it for subsequent analysis on ion-exchange liquid chromatography with VIS detector.

Abstract:
A quantitative comparison was made of the efficiency of conjugation of immunoglobulins G and gold nanoparticles obtained by the Turkevich-Frens method. The conjugates were synthesized by physical adsorption and covalent immobilization using orthopyridyl disulfide polyethylene glycol succinimidyl ester (OPSS-PEG-NHS). [..]

Abstract:
Metalloproteins (MTs) are one of the most diverse classes of proteins, with the intrinsic metal atoms providing a catalytic, regulatory and structural role crucial to protein functioning. When stored under aerobic conditions, MTs might form dimers (as well as higher oligomers) that play an essential role as mediators in oxidoreduction signalling pathways. [..]

Abstract:
Nucleobases are the main building blocks in DNA and RNA playing very important roles in cell metabolism. Changes of bases in DNA sequence may affect function of products of gene expression – proteins, and this can lead to inherited diseases and most human cancer types. [..]

Abstract:
In this contribution, we present the new approach for plasmon assisted grafting of anisotropic gold nanorods (AuNRs) with spatial selectivity, which was used for creation of nanoparticles with amphiphilic surface. The surface modification was carried out in two stages with implementation of: (I) the plasmon-activated iodonium salt (IS), and (II) the aryl diazonium salt (ADT). [..]
