A U⋅U pair-to-U.C pair mutation-induced RNA native structure destabilisation and stretching-force-induced RNA misfolding
Published 2015“…The ensemble thermal melting of the hairpins shows an on-pathway intermediate with the disruption of the internal loop structure containing the U⋅U/U⋅C pairs. By using optical tweezers, we applied a stretching force on the terminal ends of the hairpins to probe directly the non-nearest-neighbour effects upon the mutations. …”

Symmetry-protected dual bound states in the continuum in metamaterials
Published 2020“…In photonics, it is essential to achieve high Q resonances for enhanced light-mater interactions that could enable low-threshold lasers, ultrasensitive sensors, and optical tweezers. Hence, it is important to explore BICs in different photonic systems including subwavelength metamaterials where symmetry-protected dual BICs exist. …”

Behaviour of uniformly dimpled colloidal particles
Published 2014“…Finally, the depletion induced force between lock and key particles at contact is directly measured using optical tweezers. The dependence of the force due to depletion upon the overlap volume between the particles is illustrated, and we find that the strongest force is produced when the key is held within the cavity of the dimpled lock, demonstrating semiquantitative agreement with theoretical predictions.…”

Ice rule breakdown and frustrated antiferrotoroidicity in an artificial colloidal Cairo ice
Published 2023-01-01“…We realize this particle ice by confining field tunable paramagnetic colloidal particles within a lattice of topographic double wells at a one to one filling using optical tweezers. By raising the interaction strength via an applied magnetic field, we find that the ice rule breaks down, and positive monopoles with charge $q = +2$ accumulate in the z = 4 vertices and are screened by negative ones ( $q = -1$ ) in the z = 3. …”
