Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

Advanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

A curious case: caddisfly cases built from brick and sewage overflow microplastics

Journal of Limnology
Caddisflies larvae have been constructing cases made from vegetation or sediment grains for millions of years, but in the Anthropocene many alternative building materials have become available for caddisfly larvae.
