Abstract The correlation between altered extracellular pH and various pathological conditions, including cancer, inflammation metabolic disorders, is well known. Bulk measurements cannot report the value at cell surface. However, there a limited number of suitable tools for measuring cells with high spatial resolution, none them are commonly used in laboratories around world. In this study, versatile ratiometric nanosensor measurement was developed. consists biocompatible polystyrene...
Abstract Biofilms are ubiquitous in nature and the man-made environment. Given their harmful effects on human health, an in-depth understanding of biofilms monitoring formation growth important. Particularly relevant for many metabolic processes survival strategies is extracellular pH. However, most conventional techniques not suited minimally invasive pH measurements living biofilms. Here, a fluorescent nanosensor presented ratiometric range 4.5–9.5 using confocal laser scanning microscopy....
Bacterial biofilms can pose a serious health risk to humans and are less susceptible antibiotics disinfection than planktonic bacteria. Here, novel method for biofilm eradication based on antimicrobial photodynamic therapy utilizing nanoparticle in conjunction with BODIPY derivative as photosensitizer was developed. Reactive oxygen species generated upon illumination visible light lead strong, controllable persistent of both bacteria biofilms. One the biggest challenges is penetration agent...
This article reviews the current status of nanotechnology with emphasis on application and related environmental considerations as well legislation. Application analysis nanomaterials in infrastructure (construction, building coatings, water treatment) is discussed, particular nanomaterial release during lifecycle these applications. Moreover, possible grouping approaches regard to ecotoxicological toxicological properties, fate environment are evaluated. In terms potential exposure,...
A broad range of inorganic nanoparticles (NPs) and their dissolved ions possess a possible toxicological risk for human health the environment. Reliable robust measurements dissolution effects may be influenced by sample matrix, which challenges analytical method choice. In this study, CuO NPs were investigated in several experiments. Two techniques (dynamic light scattering (DLS) inductively-coupled plasma mass spectrometry (ICP-MS)) used to characterize (size distribution curves)...
