Inkjet printing technology commonly known from home-use inkjet printers has become a tool for industrial-scale mass fabrication. Our laboratory is making use of this technology in combination with paper substrates to develop low-cost, single-use and simple chemical sensors for clinical and environmental applications.

Our laboratory’s research goal is the development of highly sensitive and selective chemical sensors and biosensors. Here, we present (1) novel bright fluorescent and chemiluminescent dyes for various target analytes, (2) functional nanomaterials for medical and environmental sensing, and (3) fluorescent probes for selective bioimaging.

It is important to detect person with Autism Spectrum Disorder (ASD) early to get treatment and education. Recently, the research on olfactory feature of them is advanced. And it is reported that odor detection ability in children with ASD was impaired. In this study, we assess olfaction of children to screen for ASD by olfaction.

We will present you an innovative laser technology extending vascular wall without cracks. We reserved number of patents and have practical experiences. We will demonstrate the latest operation of newly developed angioplasty device to extend atherosclerosis vessels as well as drug delivery system, both with heating.

Our Arai Lab. presents unique therapeutic systems from the results of basic studies and our patents. Our unique developed systems will be exhibited and demonstrated in our section.

We have proposed PD Ablation as an application of Photodynamic Therapy to a non-thermal arrythmia treatment without any side effects and developed a clinical device. We will present new findings of in vitro and in vivo studies.
