What we do

The Micro-Nano Innovation Lab ("mini lab") @Hamlyn investigates and utilises light-matter interactions to develop new intelligent sensing and robotic strategies in micro/nano scales. The research involves designing and fabricating micro/nanostructures for diagnostics (e.g. infections, cancer, neurodegenerative diseases) and microscopic therapies/surgeries (e.g. localised drug delivery, novel minimally invasive treatment).

TY  - JOUR
AB  - In this article, we demonstrate a plasmo-thermal bacterial accumulation effect usinga miniature plasmonic optical fiber. Combined action of far-field convection and a near-fieldtrapping force (referred to as thermophoresis)—induced by highly localized plasmonicheating—enabled large-area accumulation of Escherichia coli. The estimated thermophoretictrapping force agreed with previous reports, and we applied speckle imaging analysis to mapthe in-plane bacterial velocities over large areas. This is the first time that spatial mapping ofbacterial velocities has been achieved in this setting. Thus, this analysis technique providesopportunities to better understand this phenomenon and to drive it towards in vivo applications.
