Label-free Brillouin endo-microscopy for the quantitative 3D imaging of sub-micrometre biology (2024)
Journal Article

This report presents an optical fibre-based endo-microscopic imaging tool that simultaneously measures the topographic profile and 3D viscoelastic properties of biological specimens through the phenomenon of time-resolved Brillouin scattering. This u... Read More about Label-free Brillouin endo-microscopy for the quantitative 3D imaging of sub-micrometre biology.

Classification of cancer cells at the sub-cellular level by phonon microscopy using deep learning (2023)
Journal Article

There is a consensus about the strong correlation between the elasticity of cells and tissue and their normal, dysplastic, and cancerous states. However, developments in cell mechanics have not seen significant progress in clinical applications. In t...

Living cells as a biological analog of optical tweezers – a non-invasive microrheology approach (2023)
Journal Article

Microrheology, the study of fluids on micron length-scales, promises to reveal insights into cellular biology, including mechanical biomarkers of disease and the interplay between biomechanics and cellular function. Here a minimally-invasive passive... Read More about Living cells as a biological analog of optical tweezers – a non-invasive microrheology approach.

Phonon imaging in 3D with a fibre probe (2021)
Journal Article

We show for the first time that a single ultrasonic imaging fibre is capable of simultaneously accessing 3D spatial information and mechanical properties from microscopic objects. The novel measurement system consists of two ultrafast lasers that exc... Read More about Phonon imaging in 3D with a fibre probe.

3D phonon microscopy with sub-micron axial-resolution (2021)
Journal Article

© 2021, The Author(s). Brillouin light scattering (BLS) is an emerging method for cell imaging and characterisation. It allows elasticity-related contrast, optical resolution and label-free operation. Phonon microscopy detects BLS from laser generate...

Time resolved Brillouin fiber-spectrometer (2019)
Journal Article

This report introduces a novel time resolved Brillouin spectrometer, consisting of an opto-acoustic transducer which resides on the tip of a single-mode optical fiber of arbitrary length with 125 µm outer diameter and 5 µm sensing diameter. Demonstra... Read More about Time resolved Brillouin fiber-spectrometer.

New insights into the mechanical properties of Acanthamoeba castellanii cysts as revealed by phonon microscopy (2019)
Journal Article

The single cell eukaryotic protozoan Acanthamoeba castellanii exhibits a remarkable ability to switch from a vegetative trophozoite stage to a cystic form, in response to stressors. This phenotypic switch involves changes in gene expression and synth...

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.

Sound of nano (2013)
Journal Article

Ultrasound is widely used for imaging, measurement and diagnostics in the MHz region and is perhaps most familiar as a medical or non-destructive imaging or measurement tool. In the MHz frequency range the wavelength is typically measured in microns... Read More about Sound of nano.
