In the post-COVID-19 pandemic era, the long-term surveillance of pathogens is still important. The rapid detection of pathogens facilitates the accurate and convenient real-time monitoring of microbial contamination and improves the management of diseases. Here, a novel surface plasmon resonance (SPR)-based point of care testing (POCT) approach of microorganism nucleic acids with the guidance of CRISPR enzyme is described, including the application of optical fiber-based detection of trace SARS-CoV2 virus in sewage water on SPR and validation of the plasmonic biosensor for the detection of single-nucleotide mutations in natural water samples.

Introduction:Traditional methods for determining radiation dose in nuclear medicine include the Monte Carlo method,the discrete ordinate method,and the point kernel integration *** study presents a new mathematical model for predicting the radiation dose rate in the vicinity of nuclear medicine ***:A new algorithm was created by combining the physical model of“cylinder superposition”of the human body with integral analysis to assess the radiation dose rate in the vicinity of nuclear medicine ***:The model accurately predicted radiation dose rates within distances of 0.1–3.0 m,with a deviation of less than 11%compared to observed *** model demonstrated greater accuracy at shorter distances from the radiation source,with a deviation of only 1.55%from observed values at 0.1 ***:The model proposed in this study effectively represents the spatial and temporal distribution of the radiation field around nuclear medicine patients and demonstrates good agreement with actual *** model has the potential to serve as a radiation dose rate alert system in hospital environments.
