Summary: Detection via nanohole is a simple sensing tool to analyze various biopolymers with high sensitivity. The combination of conical-shaped Si micro-nanopore and graphene nanohole shows significant ionic current blockade detection, indicating the potential for high sensitive DNA biosensors. The sensitivity of around 110 nA/μL for both devices is relatively higher compared to other literatures.

Summary: Sensory receptors play a crucial role in biological systems as they allow organisms to perceive and adapt to their environment. Researchers have developed biomimetic sensors to mimic the sensory transduction of organisms, but selectivity and multi-sensing capabilities in soft self-healing sensors (SSHS) are still lacking. This paper discusses the multi-sensing aspect of SSHS, focusing on resistive-based sensors for detecting various stimuli. Inspiration from biological systems' sensory transduction will be key for the further development and application of SSHS in areas such as soft robotics, electronic skin, and haptic devices.

Summary: Novel Fe86-xP11C2B1Inx (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) amorphous alloys were developed in this study. After appropriate annealing, Fe85.8P11C2B1In0.2 nanocrystalline alloy with low coercivity (2.9-21.0 A/m) and high saturation magnetization (1.63-1.73 T) was obtained. The nanocrystalline structure was confirmed by XRD and TEM, and In microalloying was found to induce nanocrystallization in FePCB amorphous alloy according to Kissinger's plot. This provides a new approach for developing Fe-based nanocrystalline soft magnetic alloys.
