A Genetic Reporter for Visualizing Nitroreductase Activity Using Magnetic Resonance Imaging
Chemistry–Methods, Volume 6, Issue 5, May 2026.We introduce a reporter gene technology to noninvasively visualize bacterial nitroreductase activity. Our method utilizes a magnetic resonance imaging (MRI) reporter based on aquaporin, which is fused to a destabilizing domain, resulting in their degradation (off‐state).

A 12-Gb/s Stacked Dual-Channel Interface for CMOS Image Sensor Systems
Sensors, 2018 We propose a dual-channel interface architecture that allocates high and low transition-density bit streams to two separate channels. The transmitter utilizes the stacked drivers with charge-recycling to reduce the power consumption.
