Cell imaging using sub-optical wavelength ultrasonics (2015)
Presentation / Conference Contribution
Clark, M., Marques, L., Moradi, E., Perez-Cota, F., Smith, R. J., & Webb, K. F. (2015). Cell imaging using sub-optical wavelength ultrasonics. In Proceedings Asia Communications and Photonics Conference 2015. https://doi.org/10.1364/acpc.2015.asu5h.1

At GHz frequencies the wavelength of ultrasound becomes comparable or smaller than the wavelength of light and so offers an intriguing way to image at the small scale. In this paper we report on new developments in pico-second laser ultrasonics that... Read More about Cell imaging using sub-optical wavelength ultrasonics.

Thin-film transducers for the detection and imaging of Brillouin oscillations in transmission on cultured cells (2015)
Journal Article
Perez-Cota, F., Smith, R. J., Moradi, E., Webb, K. F., & Clark, M. (in press). Thin-film transducers for the detection and imaging of Brillouin oscillations in transmission on cultured cells. Journal of Physics: Conference Series, 684(1), https://doi.org/10.1088/1742-6596/684/1/012003

Mechanical imaging and characterisation of biological cells has been a subject of interest for the last twenty years. Ultrasonic imaging based on the scanning acoustic microscope (SAM) and mechanical probing have been extensively reported. Large acou...

Thin-film optoacoustic transducers for the subcellular Brillouin oscillation imaging of individual biological cells (2015)
Journal Article
Perez-Cota, F., Smith, R. J., Moradi, E., Marques, L., Webb, K. F., & Clark, M. (2015). Thin-film optoacoustic transducers for the subcellular Brillouin oscillation imaging of individual biological cells. Applied Optics, 54(28), https://doi.org/10.1364/AO.54.008388

Mechanical characterisation and imaging of biological tissue has piqued interest in the applicability to cell and tissue biology. One method, based on detection of Brillouin oscillations, has already lead to demonstrations on biological cells using u...

Optically excited nanoscale ultrasonic transducers (2015)
Journal Article
Smith, R. J., Cota, F. P., Marques, L., Chen, X., Arca, A., Webb, K., …Clark, M. (2015). Optically excited nanoscale ultrasonic transducers. Journal of the Acoustical Society of America, 137(1), 219-227. https://doi.org/10.1121/1.4904487

© 2015 Acoustical Society of America. In order to work at higher ultrasonic frequencies, for instance, to increase the resolution, it is necessary to fabricate smaller and higher frequency transducers. This paper presents an ultrasonic transducer cap... Read More about Optically excited nanoscale ultrasonic transducers.

Sub-100 nm resolution microscopy based on proximity projection grating scheme (2015)
Journal Article
Hu, F., Somekh, M. G., Albutt, D. J., Webb, K., Moradi, E., & See, C. W. (2015). Sub-100 nm resolution microscopy based on proximity projection grating scheme. Scientific Reports, 5, Article 8589. https://doi.org/10.1038/srep08589

Structured illumination microscopy (SIM) has been widely used in life science imaging applications. The maximum resolution improvement of SIM, compared to conventional bright field system is a factor of 2. Here we present an approach to structured il...
