Gold nanoparticles have demonstrated significant radiosensitization of cancer treatment with X-ray radiotherapy. To understand the mechanisms at the basis of nanoparticle radiosensitization, Monte Carlo simulations are used to investigate the dose enhancement, given a certain nanoparticle concentration and distribution in the biological medium. Ear...
Nanomaterials designed for biomedical applications are expected to establish contact with physiological fluids, which contain a wide variety of biomolecules and cellular entities. It is now well-accepted that when a nanomaterial comes into contact with a biological fluid, its nature and physico-chemical properties can be affected by the formation o...

Background: Electroporation has become a routine technique for rapid drug delivery for the treatment of cancer. Because of its simplicity and wide range of application, it has been applied for the transfer of gold-nanoparticles and can facilitate entry into target cancer cells. Objective: The aim of this study is finding optimal conditions in order...
Abstract The projections for the global energy demand have been one of our society’s greatest challenges, which has contributed significantly to the search for new sources of energy, among which biodiesel stands out and, consequently, the development of methods for quality assurance is essential to ensure its technological demand. In this context, ...

Gold nanoparticles are the most promising candidate in cancer treatment due to their physiochemical properties
and increased use in photothermal therapy (PTT). In the present study, spherical gold nanoparticles (AuNPs) were
synthesized using citrate reduction method. The particles were then characterized using UV-VIS spectroscopy and
transmission e...

The synthesis of star-like gold nanoparticles (SGNs) in a temperature-controlled environment allows for temperature modulation and facilitates the growth of highly branched nanoparticles. By increasing the synthesis temperature, the level of branching increases as well. These highly branched features represent a distinctly novel, quasi-fractal nano...

We designed an enzymatic biofuel cell (EFC) that utilizes indium tin oxide (ITO) electrodes, and sequential deposition of single-walled carbon nanotube (SWCNT) and gold nanoparticle (AuNP) layers on the electrodes to enhance their electron transfer. Cyclic voltammograms of the SWCNT-modified ITO electrodes showed higher peak currents compared to th...
Tato bakalářská práce seznamuje se základními znalostmi a historií elektrochemické impedanční spektroskopie (EIS). V práci je též popsán způsob měření EIS, a dále jsou zmíněny i souvislosti týkající se přesahů do elektrochemie, teorie senzorů a nanočástic. Hlavním těžištěm práce je zpracování dat, v tomto případě ve dvou různých programech, který s...

Preventing ice formation during cryopreservation by vitrification has led to the successful storage and banking of numerous cellular- and tissue-based biomaterials. In their breakthrough work, Peter Mazur's group achieved over 90% survival by using a laser warming technique for 100 μm mice oocytes that were cooled in 0.1 μL droplets with 2.3 M CPA ...
