Quadratic nonlinearities of gold nanoprisms in solution: the role of corner sharpness

The size and shape (nanospheres, nanorods, nanostars…) of metallic nanoparticles significantly affect their physical and chemical properties. Among these nanostructures, acentric objects are expected to display high quadratic nonlinear responses,…

Very Accurate Flexible pH Microsensor Based on Nanoporous Titanium Nitride Material for In Vivo Application

Recently, the need for a real-time and less invasive solution to replace in-laboratory blood analysis by analyzing in situ biological fluids (sweat, saliva, tear, urine, and interstitial fluid) has grown alongside the development of microfabrication…

Optofluidic Sensor Based on Polymer Optical Microresonators for the Specific, Sensitive and Fast Detection of Chemical and Biochemical Species

The accurate, rapid, and specific detection of DNA strands in solution is becoming increasingly important, especially in biomedical applications such as the trace detection of COVID-19 or cancer diagnosis. In this work we present the design,…

Enabling quantum sensing under extreme pressure: Nitrogen-vacancy magnetometry up to 130 GPa

Engineering a layer of nitrogen-vacancy (NV) centers on the tip of a diamond anvil creates a multipurpose quantum sensor array for high-pressure measurements, especially for probing the magnetic and superconducting properties of materials. Expanding…

Interplay of structure and photophysics of individualized rod-shaped graphene quantum dots with up to 132 sp² carbon atoms

Nanographene materials are promising building blocks for the growing field of low-dimensional materials for optics, electronics and biophotonics applications. In particular, bottom-up synthesized 0D graphene quantum dots show great potential as…

Shortcuts to Equilibrium with a Levitated Particle in the Underdamped Regime

We report on speeding-up equilibrium recovery in the previously unexplored general case of the underdamped regime using an optically levitated particle. We accelerate the convergence toward equilibrium by an order of magnitude compared to the…
