The urgent need for field detection of uranium in seawater is 2-fold: to provide prompt guidance for uranium extraction and to prevent human exposure to nuclear radiation. However, current methods for this purpose are largely hindered by bulky instrumentation, high costs of developed materials, and severe matrix interferences, which limit their further application in the field. Herein, we demonstrated a portable and label-free strategy for the field detection of uranyl in seawater based on the efficient photocleavage of DNA.

Article Synopsis
  • Salivary pepsin is a potential diagnostic marker for gastroesophageal reflux disease (GERD), but its detection is complicated due to its activity being dependent on acidic conditions (pH ∼ 2) while saliva is neutral.
  • A new fluorescence assay has been developed to detect pepsin at neutral pH by leveraging its electrostatic interaction with SYBR Green, resulting in an increase in fluorescence intensity without needing active pepsin.
  • A smartphone-based device was created to enable quick and accurate pepsin detection in saliva, achieving results in just 3 minutes and a detection limit of 0.2 μg/mL, facilitating noninvasive GERD diagnosis.

Hydrolytic dehydrogenation of ammonia borane is a significant and promising approach for on-site hydrogen production at ambient conditions, and developing highly efficient and low-cost catalysts has attracted considerable attention. Herein, waste-biomass-derived activated carbon (AC) was prepared by hydrothermal carbonization and alkali-assisted activation, and non-precious bimetal phosphides (Co-Cu-P) nanocatalysts with a series of different Co/Cu ratios were synthesized on the AC surface through phosphidation method. Owing to the synergetic effects, the optimal CoCuP/AC presents an outstanding turnover frequency of 26.
