Following a radiological or nuclear incident, the National Response Plan has given the Department of Health and Human Services / Centers for Disease Control and Prevention the responsibility for assessing population's contamination with radionuclides. In the public health response to the incident, valuable information could be obtained in a timely and accurate manner by using liquid scintillation counting techniques to determine who has been contaminated above background for alpha and beta emitting radionuclides. The calibration plays a major role in this process therefore, knowing the effect of quench agents on calibration is essential.

Organic photosensitizers (PSs) possessing NIR-II emission and photodynamic/photothermal effect have received a great sense of attention for their cutting-edge applications in imaging-guided multimodal phototherapy. However, it is highly challenging to design efficient PSs with high luminescence and phototherapy performance simultaneously. In this study, a spiro-functionalization strategy is proposed to alleviate aggregate-caused quenching of PSs and promote photodynamic therapy, and the strategy is verified via a spiro[fluorine-9,9'-xanthene]-modified NIR-II PS (named SFX-IC) with an acceptor-donor-acceptor configuration.

Late diagnosis is one of the major obstacles for the treatment of breast cancer which can be overcome with a system offering sensitive imaging and selective therapeutic effect. In this study, we developed a "dark-bright" multifunctional drug delivery system bringing real-time imaging and non-invasive therapy together. Theranostic ability of the system was delivered by Verteporfin (VP), serving as a fluorescence probe and a photosensitizer.

Phosphate pollution leads to the deterioration of water quality, posing a serious threat to human health. Tetracycline hydrochloride (TC), a class of broad-spectrum bacteriostatic agents, has garnered attention due to its extensive use and potential toxicity. Therefore, developing a highly selective and sensitive fluorescent probe for the detection of phosphates and TC is of significant importance.
