A Fiber Optoacoustic Emitter with Maximized Conversion Efficiency and Controlled Ultrasound Frequency for Biomedical Applications
Linli Shi, Ying Jiang, Yi Zhang +4
Focused ultrasound has attracted great attention in minimally invasive therapy, gene delivery, brain stimulation, etc. Frequency below 1 MHz has been identified preferable for high…
Ultra-Efficient Conversion of Microwave into Ultrasound Wave through a Split Ring Resonator
Lu Lan, Yueming Li, Tiffany Yang-Tran +2
Thermo-elastic conversion of electromagnetic wave into ultrasound wave has enabled diverse biomedical applications such as photoacoustic imaging. Microwave, which has ~10 cm long w…
Bond-Selective Transient Phase Microscopy
Delong Zhang, Lu Lan, Yeran Bai +4
Phase-contrast microscopy converts the optical phase introduced by transparent, unlabeled specimens into modulation in the intensity image. Modern phase imaging techniques are capa…
Ultrafast Chemical Imaging by Widefield Photothermal Sensing of Infrared Absorption
Yeran Bai, Delong Zhang, Lu Lan +4
Infrared (IR) imaging has become a viable tool for visualizing various chemical bonds in a specimen. The performance, however, is limited in terms of spatial resolution and imaging…
