DNA Sensing with Whispering Gallery Mode Microlasers
Soraya Caixeiro, Robert Dörrenhaus, Anna Popczyk +3
Nucleic acid sensing is crucial for advancing diagnostics, therapeutic monitoring and molecu-lar biology research, by enabling the precise identification of DNA and RNA interaction…
Optical Manipulation of Whispering Gallery Mode Microlasers for Precision Controlled Cellular Delivery
Soraya Caixeiro, Paloma Rodríguez-Sevilla, Kishan Dholakia +1
Whispering gallery mode microlasers are known for their high Q-factors, characteristic emission spectra and sensitivity to local refractive index changes. This sensitivity combined…
Snapshot hyperspectral imaging of intracellular lasers
Soraya Caixeiro, Philip Wijesinghe, Kishan Dholakia +1
Intracellular lasers are emerging as powerful biosensors for multiplexed tracking and precision sensing of cells and their microenvironment. This sensing capacity is enabled by qua…
Local sensing of absolute refractive index during protein-binding using microlasers with spectral encoding
Soraya Caixeiro, Casper Kunstmann-Olsen, Marcel Schubert +5
Multiplexed, specific and sensitive detection of antigens is critical for the rapid and accurate diagnosis of disease and the informed development of personalized treatment plans.…
Flexible and tensile microporous polymer fibers for wavelength-tunable random lasing
Van Duong Ta, Dhruv Saxena, Soraya Caixeiro +1
Flexible and tensile wavelength-tunable micrometer-sized random lasers in the form of microporous polymer fiber are demonstrated. The fibers are fabricated by directly drawing from…
Microsphere solid state biolasers
Van Duong Ta, Soraya Caixeiro, Francisco M. Fernandes +1
Microsphere solid-state biolasers made of biomaterials-bovine serum albumin, pectin and cellulose are demonstrated. The fabrication is simple, based on emulsion, and with green pro…
Disordered Cellulose-based Nanostructures for Enhanced Light-scattering
Soraya Caixeiro, Matilda Peruzzo, Olimpia D. Onelli +2
Cellulose is the most abundant bio-polymer on earth. Cellulose fibres, such as the one extracted form cotton or woodpulp, have been used by humankind for hundreds of years to make…
Explaining the mechanism of random lasing based sensing
Michele Gaio, Soraya Caixeiro, Benedetto Marelli +2
Here we report a random lasing based sensor which shows pH sensitivity exceeding by 2-orders of magnitude that of a conventional fluorescence sensor. We explain the sensing mechani…
