Stretchable and Robust Candle-Soot Nanoparticle-Polydimethylsiloxane Composite Films for Laser-Ultrasound Transmitters

Autor: Muhammad Faraz, Muhammad Awais Abbasi, Pilgyu Sang, Donghee Son, Hyoung Won Baac

Publikováno v: Micromachines, Vol 11, Iss 7, p 631 (2020)

Considerable attention has been devoted to the development of nanomaterial-based photoacoustic transmitters for ultrasound therapy and diagnosis applications. Here, we fabricate and characterize candle-soot nanoparticles (CSNPs) and polydimethylsilox

Laser-generated focused ultrasound transmitters with frequency-tuned outputs over sub-10-MHz range

Autor: Hyoung Won Baac, Pilgyu Sang, Hui Joon Park, Jeongmin Heo, Min Gyu Joo, Kyu-Tae Lee

Publikováno v: Applied Physics Letters. 115:154103

Previous laser-generated focused ultrasound (LGFU) systems have been operated with >15 MHz frequency, allowing for high spatial precision ( 15 MHz frequency, allowing for high spatial precision (

High-frequency optoacoustic transmitter based on nanostructuredgermanium via metal-assisted chemical etching

Autor: Junseok Heo, Geonwook Yoo, Hyoung Won Baac, Pilgyu Sang, Youngseo Park

Publikováno v: OPTICAL MATERIALS EXPRESS(6): 8

We propose the use of nanostructured germanium (Ge) fabricated by simple metalassisted chemical (MAC) etching as a high-frequency optoacoustic ultrasound transmitter. As an acoustic transfer medium, an elastomeric polymer, polydimethylsiloxane (PDMS)
