Advancing Multi‐Ion Sensing with Poly‐Octylthiophene: 3D‐Printed Milker‐Implantable Microfluidic Device (Adv. Sci. 47/2024)

3D-Printed Milker-Implantable Microfluidic Device In article number 2408314, Md. Azahar Ali and Matin Ataei Kachouei introduce a pocketsized, 3D-printed sensing platform for on-site detection of Fe2+, NO3−, Ca2+, and HPO42−. With a printed transducing layer for high sensitivity (detecting ions as low as 1 ppm), its nnovative 3D-wrinkled surface and microfluidic system enable real-time milk parameter monitoring, providing farmers with actionable insights for improved livestock health and farm management.
