High sensitivity strain sensor based on twin hollow microspheres
A sensor based on 2 hollow core microspheres is proposed. Each microsphere was produced separately through fusion splicing and then joined. The resultant structure is a Fabry-Perot interferometer with...
PublicationsBeer’s law derived from Electromagnetic Theory
We present a rigorous derivation of Beer’s law from electromagnetic theory. As a result of this derivation, the attenuation constant is shown to be a function of the index of refraction. For small concentrations...
PublicationsRaman and infrared spectroscopy reveal that proliferating and quiescent human fibroblast cells age by biochemically similar but not identical processes
Dermal fibroblast cells can adopt different cell states such as proliferation, quiescence, apoptosis or senescence, in order to ensure tissue homeostasis. Proliferating (dividing) cells pass through the...
PublicationsHigh-fidelity multimode fibre-based endoscopy for deep brain in vivo imaging
Progress in neuroscience relies on new techniques for investigating the complex dynamics of neuronal networks. An ongoing challenge is to achieve minimally invasive and high-resolution observations of...
PublicationsTip-enhanced Raman imaging of single-stranded DNA with single base resolution
Tip-enhanced Raman scattering (TERS) is a promising optical and analytical technique for chemical imaging and sensing at single molecule resolution. In particular, TERS signals generated by a gap-mode...
PublicationsDielectric function decomposition by dipole orientation distribution: Application to triclinic K2Cr2O7
Here we present a general approach for the description of the dielectric function. Based on symmetry arguments we show that the components of the dielectric tensor are in general not independent of each...
PublicationsSuccessful optimization of reconstruction parameters in structured illumination microscopy – A practical guide
The impact of the different reconstruction parameters in super-resolution structured illumination microscopy (SIM) on image artifacts is carefully analyzed. These parameters comprise the Wiener filter...
PublicationsMicroparticle Manipulation and Imaging through a Self-Calibrated Liquid Crystal on Silicon Display
We present in this paper a revision of three different methods we conceived in the framework of liquid crystal on silicon (LCoS) display optimization and application.We preliminarily demonstrate an LCoS...
PublicationsControlled growth of transition metal dichalcogenide monolayers using Knudsen-type effusion cells for the precursors
Controlling the flow rate of precursors is essential for the growth of high quality monolayer single crystals of transition metal dichalcogenides (TMDs) by chemical vapor deposition. Thus, introduction...
PublicationsPhotoannealing of Merocyanine Aggregates
In this work we elucidate the fundamental difference between aggregate formation of donor−π−acceptor merocyanines in their electronic ground and excited states. While increasing the π-bridge size...
