Real-time, continuous, and precise monitoring of vital signs in vivo is essential for detecting early signs of dysfunction of the organs and enabling timely intervention. For example, conditions like acute ischemic stroke constitute 87% of all stroke cases and post-surgical atrial fibrillation occurs in 20-50% of patients after cardiac surgery, underscore the critical need for predictive monitoring of these organs.

1. 논문관련 분야의 소개, 동향, 전망을 설명, 연구과정에서 생긴 에피소드 인체 내 깊숙하고 접근하기 어려운 작은 공간에서 작동할 수 있는 차세대 혈관 내 임플란트 (intravascular implants) 및 생체의학 마이크로 로봇 분야에 대한 많은 연구들이 실행되고 있습니다. 하지만, In-vivo applications을 위한 오늘날의 가장 작은 에너지 저장 장치는 3mm 3 보다 크고, 마이크로 로봇 시스템의 복잡한 기능을 지속적으로 구동할 수 있는 능력이 부족합니다. 따라서, 저희는 작은 부피 (1/1000mm 3 )와 독성이 없는 소재로 구성되어, 혈액에 자연적으로 존재하는 산화환원 효소 (redox enzymes)와 살아있는 세포를 이용해 장치의 성능을 약 40% 향상시켰고, 소형 슈퍼커패시터 (supercapacitor)가 지속적으로 직면한 자가 방전 (self-discharge) 문제를 해결하였습니다. 또한, 관형 구조를 통해, 혈류 시스템에 방해받지 않고, 맥동하는 혈액 또는 혈관 내 근육 수축으로 인한 외부 힘으로부터 효율적인 자체 보호를 할수 있으며, 통합 센서 시스템을 구동하여 혈액의 pH 값을 측정할 수 있는 관형 바이오 슈퍼커패시터 (Tubular biosupercapacitor)를 개발하였습니다. 본 연구를 통해 Tubular biosupercapacitor가 생체의학 산업에 유용하게 쓰일 수 있는 발전 가능성을 보여주었고, 앞으로 실응용을 위한 많은 연구가 활발히 이루어질 것으로 전망됩니다. 그림.

1. 논문관련 분야의 소개, 동향, 전망을 설명, 연구과정에서 생긴 에피소드 The use of optogenetics in the brain has revolutionized the interrogation of neural circuitry by enabling temporal and spatial control of neuronal function. This approach utilizes light-sensitive channels, receptors, or pumps to activate, inhibit, or modulate neuronal activity. Activation or inhibition of neuronal pathways both in vitro and in vivo using these light-activated proteins has enabled detailed mapping of neuronal circuits and unprecedented insights into neuronal functions. Substantial interest has developed in utilizing optogenetics to dissect neural pathways involved in the brain. Furthermore, optogenetics offers the possibility of novel, nonpharmacologic approaches to managing chronic pain and itching, which afflict millions of people. However, attempts to apply optogenetic studies to tissues beyond the brain are stymied by the inability to target peripheral and spinal circuits in freely-moving animals. Studies to date have primarily utilized cumbersome tethered fiber optic cables or light emitting diode (LED) arrays to activate opsins that are expressed transgenically or delivered through gene therapy. Although these experimental approaches have utility, physical tethers impede movement which can alter behaviors and frustrate the natural motion of animals in complex environments. This has limited the ability to optogenetically manipulate neural circuits in behavioral assays, and complicates the interpretation of behavioral data. In addition to their use for basic research, optogenetics triggered by wireless platforms can have long-term potential to serve as important clinical tools. Gene therapy that could be used to deliver optogenetic channels to human cells is already in clinical trials, and with the appropriate testing these optogenetic stimulators could be adapted for use in treating malfunction of neural circuits in the brain or chronic intractable human diseases.
