많이 들어 와 들어 보길.
강사는 우리 학부를 졸업하고 스탠포드로 유학 갔던 똑똑한 여학생들 중 한 명. (전에 한 번 세미나 했던 이진형 박사는 UCLA 교수로 가는 것 같고…)
분야는 좀 다르지만 우리 연구실의 졸업 논문과 스탠포드의 졸업 논문 수준도 비교할 겸…

Abstract

The ability to image through tissue with high resolution in vivo enables non-invasive early cancer detection in humans and therapeutic research in live pre-clinical animal models.
The dual-axes confocal (DAC) microscope architecture is proposed to miniaturize a tabletop microscope into a handheld or endoscope-compatible size.
I will present the 2-D (two-dimensional) MEMS scanner that enables in vivo real-time imaging in the DAC configuration.
It consists of a 2-D gimbal structure in double silicon-on-insulator (SOI) layers and is actuated by electrostatic vertical combdrives.
In the second part, I will present a handheld DAC microscope system where the MEMS scanner is aligned and integrated with miniature optics. Deep tissue imaging with 3-D reconstruction is demonstrated.
Finally, the application of the miniaturized DAC microscope in in vivo intravital imaging will be shown in therapeutic research of siRNA silencing in the skin.
