Small Methods, Volume 9, Issue 8, August 20, 2025.An opto‐electronic graphene‐based biosensor detects immunoglobulin M (IgM) at 100 zeptomolar (10−19 M) concentration. It features a biofunctionalized gold electrode capacitively coupled to a graphene electrode via a water‐soaked paper strip. Surface potential changes induced by few affinity events are transduced as shifts of the graphene phonon ...

Advanced Materials, Volume 37, Issue 25, June 26, 2025.As defect density in 3D perovskites is controlled by adjusting excess formamidinium iodide concentration, shallow defects acts as a carrier sink for amplified spontaneous emission (ASE). A comprehensive charge carrier dynamic model is presented to understand the critical factor of the reduction of ASE threshold.
