Fungal DNA‐barcoding on a chip: Magnetoresistive biosensors for yeast infection diagnosis
VIEW, Volume 6, Issue 6, December 2025.The development of a fungal pathogen identification chip is herein demonstrated. Hybridization dynamics were tested against 58 species in silico and 4 species on chip. 95% accuracy, 91% sensitivity, 98% specificity and femtomolar limit of detection were achieved. Future perspectives include the integration of sample pre‐treatment modules.

Chasing Charge Carriers: Diffusion Dynamics in Mixed‐n Quasi‐2D Colloidal MAPbBr3 Perovskites
Advanced Functional Materials, Volume 35, Issue 34, August 22, 2025.Metal halide perovskites are noted for their tunable optical properties. Colloidal synthesis allows the formation of differently shaped perovskite nanocrystals with varying optical and carrier transport behavior. Three MAPbBr3 morphologies are characterized: nanoplatelets, nanosheets, and nanostripes.
