Summary: Optoacoustic imaging is a hybrid biomedical imaging technique that uses contrast agents to generate ultrasound waves in tissues, producing high-resolution images. Multispectral optoacoustic imaging can discriminate signals from different contrast agents and enable specific agent identification in tissues, as well as simultaneous molecular and physiological imaging. Contrast agents play essential roles in optoacoustic imaging, with various new agents being explored and applied in recent years.

Summary: Carbon dots are luminescent carbonaceous nanoparticles with chiral properties, making them particularly interesting for biomedical applications due to their low cytotoxicity and facile synthesis. Recent efforts have led to the creation of chiral carbon dots with attractive optical properties such as two-photon absorption and circularly polarized light emission. The review covers examples of molecular chirality, characterization using chiroptical spectroscopy, methods to induce chirality in nanomaterials, fabrication techniques for chiral carbon dots, their morphology and optical properties, as well as emerging applications in sensing, bioimaging, and catalysis.

Summary: This study investigates the origin and range of fluorescent organic matter (FOM) produced by environmentally sourced freshwater bacteria, challenging the binary classification of FOM as either autochthonous or allochthonous. The study demonstrates that FOM processing and production occur along a dynamic continuum, with both in-situ production by microbial processes and transportation into aquatic systems from external sources. Additionally, fluorescence intensity data for environmental bacteria isolate monocultures are presented for the first time, allowing for the assessment of the relative contribution of different bacteria to the autochthonous FOM pool.

Summary: Fluorescence and phosphorescence are important optical-physical properties of gems, which are influenced by trace elements, crystal lattice defects, and luminous molecules. Luminescence spectroscopy, specifically using an excitation-emission matrix (EEM), provides detailed information about emission and excitation peaks, as well as the presence of specific elements, defects, or luminous substances in gem materials. This review paper summarizes the applications of luminescence spectroscopy in various gem materials, while emphasizing the need for further confirmation with samples from reliable sources.
