Enhancing Small Molecule Sensing With Aptameric Functionalized Nano Devices

Advanced Materials Technologies, EarlyView.
Unveiling an ultra‐sensitive, non‐invasive neurotransmitter sensor. For the first time, a nanoscale sensor for detecting an important neurotransmitter was demonstrated using micro‐electromechanical systems (MEMS) technology. Our approach utilized field‐effect transistor (FET)‐based readout to enable pico‐molar detection of biomarkers in sweat.

Mechanically Triggered DNA Nanovehicles for Targeted Dual‐Drug Cancer Therapy

Advanced Science, EarlyView.
A mechanically triggered DNA nanovehicle is introduced that co‐releases two anticancer drugs in response to integrin‐mediated cellular forces. Cholesterol‐anchored DNA assemblies undergo force‐induced unfolding at cell–cell junctions, enabling selective, localized dual‐drug activation in cancer cells while minimizing off‐target toxicity in low‐tension ...
