Seamless interfaces between electronic devices and biological tissues stand to revolutionize disease diagnosis and treatment. However, biological and biomechanical disparities between synthetic materials and living tissues present challenges at bioelectrical signal transduction interfaces. We introduce the active biointegrated living electronics (ABLE) platform, encompassing capabilities across the biogenic, biomechanical, and bioelectrical properties simultaneously. The living biointerface, comprising a bioelectronics layout and a -laden hydrogel composite, enables multimodal signal transduction at the microbial-mammalian nexus. The extracellular components of the living hydrogels, prepared through thermal release of naturally occurring amylose polymer chains, are viscoelastic, capable of sustaining the bacteria with high viability. Through electrophysiological recordings and wireless probing of skin electrical impedance, body temperature, and humidity, ABLE monitors microbial-driven intervention in psoriasis.
电子设备与生物组织之间的无缝接口有望彻底改变疾病的诊断和治疗方式。然而,合成材料与活组织之间的生物学和生物力学差异在生物电信号转导接口处带来了挑战。我们引入了主动生物集成活体电子(ABLE)平台,该平台同时具备生物源性、生物力学和生物电特性。这种活体生物界面由生物电子布局和负载细菌的水凝胶复合材料组成,能够在微生物与哺乳动物的连接点实现多模态信号转导。通过天然直链淀粉聚合物链的热释放制备的活体水凝胶的细胞外成分具有粘弹性,能够维持细菌的高活力。通过电生理记录以及对皮肤电阻抗、体温和湿度的无线探测,ABLE监测微生物驱动的牛皮癣干预情况。
