Currently, carbon nanoparticles play a large role as carriers of various types of drugs, and also have applications in other fields of medicine, e.g., in tissue engineering, where they are used to reconstruct bone tissue. They also contribute to the early detection of cancer cells, and can act as markers in imaging diagnostics. Their antibacterial and anti-inflammatory properties are also known. This feature is particularly important in dental implantology, where various types of bacterial infections and implant rejection often occur. The search for newer and more effective treatments may lead to future use of nanoparticles on a large scale. In this work, the current state of knowledge on the possible use of nanotubes, nanodiamonds, and fullerenes in therapy is reviewed. Both advantages and disadvantages of the use of carbon nanoparticles in therapy and diagnostics have been indicated.

The condition of air quality depends on many external (the amount of pollutant emissions, intensity and type of physico-chemical changes taking place in the atmosphere and large-scale movement of air pollutant masses) as well as internal factors (such as finishing materials, room equipment, heating systems, ventilation systems, and the presence of the humans themselves). As a result, there are various risks related to air quality, including the most important ones related to microbial contamination. For this reason, it was decided to analyze the quality of internal air in terms of microbiological contamination that may occur in university lecture halls with mechanical supply and exhaust ventilation. The analysis also took into account the impact of mechanical ventilation on physical parameters such as temperature, relative humidity as well as the concentration of PM10 and PM2.5 particulate matter pollutants, thus determining the impact of the tested parameters on human health and well-being. All the obtained results were compared with the applicable permissible standards and conclusions were drawn regarding the improvement of the quality of the indoor air microclimate.
