A Flexible‐Substrate 5‐µm‐Diameter Needle Electrode: Minimizing Neuronal Death and Enabling Year‐Long Neural Recording

Advanced Materials Interfaces, EarlyView.
An electrophysiological recording technology that uses a 5‐µm‐diameter microneedle electrode device is presented. Due to the remarkable small dimension of the microneedle, the electrode provides minimal invasive neural recording in a mouse brain and enables long‐term recording exceeding the year‐long duration.

Antifouling PEG Coatings by Thiol‐Acrylate Conjugate Addition Reactions for Generation of Protein Patterns via Photobleaching‐Induced Protein Binding (PiPB) BioBitmaps Using Maskless Projection Lithography

Advanced Materials Interfaces, EarlyView.
Homo‐bifunctional PEG, acrylate‐PEG‐acrylate (PEGDA), coatings are prepared on glass and glass‐type surfaces using solvent‐free thiol‐acrylate conjugate addition reactions at room temperature. The prepared PEGDA coatings are stable, antifouling, and provide feature terminal acrylates that can act as free radical acceptors for photobleaching‐induced ...
