A vision system is a critical element to develop the driver assistance systems for improved mobility, semi-automated or fully automated driving functions, and enhancing safety. However, vision systems in the developing autonomous vehicles have been plagued by poor visibility conditions caused by glare. We demonstrate a miniaturized integrative electrical polarizer system allowing for rapid correction of multimodal glare to reveal hidden objects. We show our method enables classification of glare, fast response time and adaptability to multimodal glare.
Actin dynamics plays an important role in cell activities and drives a large range of cellular process such as cell division and cell motility. To visualize the actin dynamics, we introduce non-bleaching nanoscale imaging to capture actin dynamics over long time scales. Here, we demonstrate the high resolution quantification of actin dynamics by non-bleaching nanoscale imaging for the purpose of revealing resulting mechanical properties. Through this method, we visualized and quantified actin twisting dynamics through disassembly process by actin binding proteins.
Gold nanoparticles are ideal tools for cargo transportation. However, injection of nanoparticles into cells remains difficult. Current method utilizes laser light to heat up the particles and the surrounding media to create shock wave or air bubble to push the particle into the cells. However, high temperatures may result in cell and/or cargo damage. To solve this issue, we propose a new mechanism that utilizes mechanical force without causing high temperature. We carefully tune the geometry of gold nanoparticles to maximize the applied force on the membrane while minimizing the particle temperature. This work paves the way for further applications in cargo transportation.
