Materials and Structural Designs toward Motion Artifact-Free Bioelectronics

Chemical Reviews, Год журнала: 2024, Номер 124(10), С. 6148 - 6197

Опубликована: Май 1, 2024

Bioelectronics encompassing electronic components and circuits for accessing human information play a vital role in real-time continuous monitoring of biophysiological signals electrophysiology, mechanical physiology, electrochemical physiology. However, noise, particularly motion artifacts, poses significant challenge accurately detecting analyzing target signals. While software-based "postprocessing" methods signal filtering techniques have been widely employed, challenges such as distortion, major requirement accurate models classification, power consumption, data delay inevitably persist. This review presents an overview noise reduction strategies bioelectronics, focusing on reducing artifacts improving the signal-to-noise ratio through hardware-based approaches "preprocessing". One main stress-avoiding is elastic energies applied to bioelectronics prevent stress-induced artifacts. Various including strain-compliance, strain-resistance, stress-damping using unique materials structures explored. Future research should optimize structure designs, establish stable processes measurement methods, develop selectively separating processing overlapping noises. Ultimately, these advancements will contribute development more reliable effective healthcare diagnostics.

Porous Laser-Scribed Graphene Electrodes Modified with Zwitterionic Moieties: A Strategy for Antibiofouling and Low-Impedance Interfaces

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(4), С. 4408 - 4419

Опубликована: Янв. 17, 2024

Laser-scribed graphene electrodes (LSGEs) are promising platforms for the development of electrochemical biosensors point-of-care settings and continuous monitoring wearable applications. However, frequent occurrence biofouling drastically reduces sensitivity selectivity these devices, hampering their sensing performance. Herein, we describe a versatile, low-impedance, robust antibiofouling interface based on sulfobetaine-zwitterionic moieties. The induces formation hydration layer exerts electrostatic repulsion, protecting electrode surface from nonspecific adsorption various agents. We demonstrate through microscopy techniques that modified exhibits outstanding antifouling properties, preserving more than 90% original signal after 24 h exposure to bovine serum albumin protein, HeLa cells, Escherichia coli bacteria. performance this strategy suggests it is viable option prolonging lifetime LSGEs-based sensors when operating complex biological systems.
