The application of UV Resonance Raman spectroscopy for the differentiation of clinically relevant Candida species
Background: Candida-related infections have become a major problem in hospitals. The species identification of yeast is the prerequisite for the initiation of adequate antifungal therapy. Objectives: In...
PublicationsCalibrating photon counts from a single image
Most image capturing devices do not directly report the number of detected photons, but a value proportional to the photoelectron charge produced in a photomultiplier tube or collected in a camera pixel....
PublicationsUsing machine-learning to optimize phase contrast in a low-cost cellphone microscope
Cellphones equipped with high-quality cameras and powerful CPUs as well as GPUs are widespread. This opens new prospects to use such existing computational and imaging resources to perform medical diagnosis...
PublicationsRemoving interference-based effects from the infrared transflectance spectra of thin films on metallic substrates: A fast and wave optics conform solution
A hybrid formalism combining elements from Kramers-Kronig based analyses and dispersion analysis was developed, which allows correcting artefacts arising from electric field standing wave effects in the...
PublicationsSlit-Enhanced Chiral- and Broadband Infrared Ultra-Sensing
This work demonstrates a membrane-based chiralplasmonic metamaterial with two plasmonic absorption bandswhich can be used for broadband surface-enhanced infrared absorption (SEIRA) and vibrational circular...
PublicationsOptical Fiber Probe Viscometer based on Hollow Capillary Tube
An optical fiber probe viscometer was developed using only a single mode fiber, a hollow capillary tube, and a fusion splicer. The sensing structure consists of an air cavity with a small access hole for...
PublicationsImproving Colloidal Stability of Nanoparticles when Stored in Responsive Gel: Application and Toxicity Study
When silica nanoparticles (SiNP) are stored in aqueous solution, even for few hours, they have a tendency to form agglomerates and therefore adapt inhomogeneous structures. We have previously reported...
PublicationsSymmetry breaking-induced magnetic Fano resonances in densely packed arrays of symmetric nanotrimers
Due to unique properties and great design flexibilities, Fano resonances represent one of the most promising optical features mediated by metallic nanostructures, while the excitation of some Fano modes...
PublicationsControlled synthesis of self-assembled 3D nanostructures using metastable atomic layer deposition
An important feature of atomic layer deposition (ALD) is the fact that the coating that has been deposited is conformal to the substrate surface. Therefore, pre-patterned substrates are usually used for...
PublicationsInfection with a Brazilian isolate of Zika virus generates RIG-I stimulatory RNA and the viral NS5 protein blocks type I IFN induction and signalling
Zika virus (ZIKV) is a major public health concern in the Americas. We report that ZIKV infection and RNA extracted from ZIKV infected cells potently activated the induction of type I interferons (IFNs)....
