Goals of project:
The study aims to create a portable and compact metalens-based device that is capable to detect fluorescence signal from single diffusing objects in an aqueous solution. This device will represent a preliminary prototype of novel portable biosensors for diagnostics.
Project objective:
- numerical simulations of the performance of integrated metalenses on waveguides, taking into account the capabilities of nanofabrication centers and collaborating laboratories;
- creation of an integrated circuit with a radiation input/output channel and metalenses for focusing laser radiation, as well as collecting the photoluminescence signal and scattering of diffusing nanoparticles and molecules;
- alignment of a time-resolved optical confocal microscope with single-photon counters to perform fluorescence correlation spectroscopy of diffusing single molecules and nanoparticles using bulk optics;
- leverage of an optical setup to test the performance of an integrated metalens and detect fluorescence and light scattering of diffusing nanoparticles, fluorescent labels, and single biomarkers of diseases;
- studying the possibility of multiplexed fluorescence detection based on several channels with integral metalens, as well as testing the performance of the device during movement.
