“…The ratio of the emissions gives a signal independent of environmental factors and allows for quantitative measurement of intensity [ 10 – 12 ]. Current ratiometric probe techniques include block polymer encapsulated donor-acceptor pairs [ 3 ], colorimetric chemosensors [ 13 ], excited-state intramolecular proton transfer probes [ 14 ], photoacoustic probes [ 15 ], fluorescent nanodiamonds [ 16 ], quantum dots [ 17 ], and nanoparticles (NPs) [ 18 ].…”

Fӧrster resonance energy transfer (FRET)-based systems are widely applicable in many areas of interest. In this study, a novel FRET-based ionic material (IM) was synthesized by pairing carbazole imidazolium cation (CI + ) with fluorescein anion (Fl 2− ) through a simple ion-exchange method. The resulting IM ([CI] 2 [Fl]) was converted into an ionic nanoparticle (INP) in aqueous media for practical use for bioimaging application. The photophysical properties of the parent dyes, [CI] 2 [Fl], and INP were studied in detail. All FRET parameters were calculated in the synthesized material. [CI] 2 [Fl] exhibited a significant spectral overlap integral and an ideal theoretical FRET distance. The presence of the FRET mechanism was verified by the observed decrease in donor fluorescence lifetime and a moderate FRET efficiency in [CI] 2 [Fl]. The INP formed from [CI] 2 [Fl] was evaluated for use as a fluorescent pH probe and bioimaging agent. FRET efficiency of INP is calculated in a series of pH studies which indicates the highest efficiency at physiological pH. Whereas no FRET phenomenon is observed in highly acidic and basic conditions. The pH-dependent photophysical properties of [CI] 2 [Fl] are monitored and allow for the potential application as a fluorescent probe for the detection of acidic tissues in biological systems. The FRET-capable INP showed superior bioimaging capability in vitro as compared to the parent dye.

“…NDs are widely used in electronics, energy storage, and coating manufacturing due to their unique physicochemical properties, such as high chemical stability, superior hardness, and thermal conductivity [ 1 , 2 ]. In addition, NDs’ chemical stability and biocompatibility properties are highly desirable in medical fields, including imaging, diagnosis, and targeted drug delivery [ 3 , 4 , 5 , 6 , 7 ]. ND powders can be obtained by various methods, including dynamic synthesis; high-pressure, high-temperature synthesis (HPHT); and chemical vapor deposition (CVD).…”

Diamond particles have great potential to enhance the mechanical, optical, and thermal properties of diamond–polymer composites. However, the improved properties of diamond–polymer composites depend on the size, dispersibility, and concentration of diamond particles. In the present study, diamond–polymer composites were prepared by adding the microdiamond particles (MDPs) with different concentrations (0.2–1 wt.%) into polymers (acrylate resins) and then subjected to a photocuring process. The surface morphology and topography of the MDPs–polymer composites demonstrated a uniform high-density distribution of MDPs for one wt.% MPDs. Thermogravimetric analysis was employed to investigate the thermal stability of the MDPs–polymer composites. The addition of MDPs has significantly influenced the polymers’ thermal degradation. Absorption and emission spectra of thin layers were recorded through UV/Vis spectrophotometry and spectrofluorimetry. The obtained results revealed a significant increase in the fluorescence intensity of MDPs–polymer composites (at 1 wt.% of MDPs, a 1.5×, 2×, and 5× increase in fluorescence was observed for MDPs–green, MDPs–amber daylight, and MDPs–red resin, respectively) compared with the reference polymer resins. The obtained results of this work show the new pathways in producing effective and active 3D-printed optical elements.

“…Additionally, surface functionalization can be used to conjugate proteins, metals, drugs, polymers, and lipids [3]. It has been shown that low toxicity, chemical stability, photostability, and excellent biocompatibility of such material have been achieved [6], [13][14][15]. Finally, nanodiamonds with negatively charged NV centers can be used as a fluorescence nanosensor based on a change in state of charge during optical excitation [13], [16].…”

Nowadays, microscopy is a widely used method for analyzing various materials. In our research, we use a developed two-channel fluorescence microscope to measure objects excited with two different wavelengths, e.g. fluorescent diamond powders with nitrogen vacancies. The results obtained were compared with images illuminated with white LED observed using a microscope in the transmission mode. The measurements yielded results with satisfactory resolution and image quality. Considering that the microscope built is a budget design, so it can be a cheaper alternative to commercial devices.
