Wearable sweat sensors enable non-invasive tracking and monitoring of human physiological information, which is expected to attract wide interest and rapid development in dietary health management and disease prevention. Unfortunately, sweat sensors are limited by rapid evaporation and low secretion rates of sweat. Herein, a sweat detection patch is proposed, which integrates bionic microchannels and multiparameter electrochemical sensors.

Article Synopsis
  • The phosphate oxygen isotope (δO) technique is useful for tracking phosphorus sources and transformations, but existing pretreatment methods for sediments are not widely applicable.
  • This study focuses on optimizing the δO pretreatment process for sediments, using the Fuyang River Basin and South Lake as a case study, and compares the effectiveness of the Blake and McLaughlin methods.
  • Results showed that the Blake method is superior in phosphorus recovery and organic matter removal, and after optimizing it further, the method improved efficiency and reduced experimental time, providing a more practical solution for broader use of sediment δO technology.

Phosphate oxygen isotope analysis is an effective tool for investigating phosphorus migration and transformation in water bodies. Unfortunately, current pretreatment methods for this technology are significantly limited due to their demanding sample amount requirements, complex operation, and limited scope of application. In order to enhance the efficiency of the pretreatment process, hydrated zirconia was synthesized through liquid-phase precipitation.
