Journal ArticleDOI
The role of LiO2 solubility in O2 reduction in aprotic solvents and its consequences for Li-O2 batteries.
Lee Johnson,Chunmei Li,Zheng Liu,Yi Chen,Stefan Freunberger,Praveen C. Ashok,Bavishna B. Praveen,Kishan Dholakia,Jean-Marie Tarascon,Peter G. Bruce +9 more
TL;DR: The unified mechanism shows that low-donor-number solvents are likely to lead to premature cell death, and that the future direction of research for lithium-oxygen batteries should focus on the search for new, stable, high-donour-number electrolytes, because they can support higher capacities and can better sustain discharge.
Journal ArticleDOI
Multi-modal approach using Raman spectroscopy and optical coherence tomography for the discrimination of colonic adenocarcinoma from normal colon
Praveen C. Ashok,Bavishna B. Praveen,Nicola Bellini,Andrew Riches,Kishan Dholakia,C. Simon Herrington +5 more
TL;DR: It is demonstrated that multimodal optical analysis has the potential to achieve accurate non-invasive cancer diagnosis and both sensitivity and specificity are increased demonstrating that combining complementary optical information enhances diagnostic accuracy.
Journal ArticleDOI
Waveguide confined Raman spectroscopy for microfluidic interrogation.
TL;DR: The first implementation of the fiber based microfluidic Raman spectroscopic detection scheme, which can be scaled down to micrometre dimensions, is reported, allowing it to be combined with other microfluidsic functional devices.
Journal ArticleDOI
Optical trapping for analytical biotechnology.
Praveen C. Ashok,Kishan Dholakia +1 more
TL;DR: The ability of this technique to manipulate microparticles and measure pico-Newton forces has found several applications such as understanding the dynamics of biological macromolecules, cell-cell interactions and the micro-rheology of both cells and fluids.
PatentDOI
Fiber probe based microfludic raman spectroscopy
TL;DR: A novel fiber probe based Raman detection system on a microfluidic platform where a split Raman probe is directly embedded into a polydimethylsiloxane (PDMS) chip, demonstrating the sensitivity of the device for urea detection at relevant human physiological levels with a low acquisition time.
