Cell imaging using sub-optical wavelength ultrasonics (2015)
Conference Proceeding

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

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

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...

Highly sensitive optical fibre long period grating biosensor anchored with silica core gold shell nanoparticles (2015)
Journal Article

An optical fibre long period grating (LPG), modified with a coating of silica core gold shell (SiO2:Au) nanoparticles (NPs) deposited using the layer-by-layer method, was employed for the development of a biosensor. The SiO2:Au NPs were electrostatic... Read More about Highly sensitive optical fibre long period grating biosensor anchored with silica core gold shell nanoparticles.

Facile approach to generating polymeric nanoarrays containing populations of nanoparticles (2015)
Journal Article

The production of nanoarrays containing a population of entrapped, heterogeneous nanoparticles is reported. The nanoarray consists of a nanoporous film with pores of diameter 60-180 nm, formed from the phase separation of two immiscible polymers: pol...

Optically excited nanoscale ultrasonic transducers (2015)
Journal Article

© 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.
