Abstract

We have witnessed the flourish of bioelectronics, brain–computer interface, and brain science programme in recent decades. In this review, the up-to-date advances of dielectric, piezoelectric, and ferroelectric nanomaterials in the biomedical applications are summarised. Biomolecular detection methods have been developed, including dielectric-gated field-effect transistor, dielectrophoresis, non-linear dielectric response, and optical tweezer. Endogenous bioelectricity is a crucial in cell proliferation, migration, differentiation, intracellular communication, neuronal activity, tissue growth. Piezoelectric and ferroelectric materials can be utilised as energy transducer to monitor physiological signal, such as blood pressure or respiration, and directly stimulate cell differentiation, neuronal regeneration, tissue repairment etc. They can also catalyse the electrochemical reaction of organisms through piezoelectricity. The intrinsic relevance between neuronal and ferroelectric polarisation signals inspires the application of the ferroelectrics in the modern intelligent bioelectronics like the artificial retina.

生物医学应用中的介电、压电和铁电纳米材料
近几十年来,我们见证了生物电子学、脑机接口和脑科学项目的蓬勃发展。本文综述了介电、压电和铁电纳米材料在生物医学领域的最新研究进展。生物分子检测方法已经发展起来,包括介电门控场效应晶体管、介电电泳、非线性介电响应和光镊。内源性生物电在细胞增殖、迁移、分化、细胞内通讯、神经元活动、组织生长等方面起着至关重要的作用。压电和铁电材料可以作为能量换能器来监测生理信号,如血压或呼吸,并直接刺激细胞分化、神经元再生、组织修复等。它们还可以通过压电催化生物的电化学反应。神经元和铁电极化信号之间的内在相关性激发了铁电在人工视网膜等现代智能生物电子学中的应用。
