Abstract: [cze] [eng]

Keywords: and to evaluate their encapsulation efficiency and stability. During the optimization process; are essential biomolecules with broad applications in biomedicine; liposomes with various lecithin-to-cholesterol ratios were prepared and subsequently loaded with nucleic acids. The resulting particles were characterized using dynamic light scattering (to determine particle size and polydispersity) and zeta potential measurements (to assess their stability). Encapsulation efficiency was evaluated by horizontal gel electrophoresis. The most significant outcome of this study is the successful optimization of liposome preparation in a smaller reaction volume and the achievement of high encapsulation efficiency for commercially supplied synthetic nucleotides; particularly at higher concentrations. These findings provide a solid foundation for further development of these systems toward their application in biomedical fields.; particularly in the development of novel therapeutic and diagnostic approaches. However; such as DNA and RNA; such as liposomes. The aim of this work was to optimize the method of preparing liposomal particles encapsulating plasmid DNA and synthetic oligonucleotides; their practical use is limited by their low stability in biological environments; This bachelor's thesis focuses on the study of nucleic acid encapsulation into liposomal particles prepared using ultrasonic sonication. Nucleic acids; where they are rapidly degraded. One effective strategy for protecting these molecules is their encapsulation into nanocarriers; while the efficiency for plasmid DNA was lower; biomedicínské aplikace; dynamický rozptyl světla; enkapsulace; enkapsulační účinnost; liposomy; nanonosiče; nukleové kyseliny; oligonukleotidy; plazmidová DNA; stabilita; ultrazvuková sonifikace; zeta potenciál
