Engineering Light at the Nanoscale
Aralyse R&D advances the design and fabrication of optical metasurfaces — engineered two-dimensional nanostructures that manipulate light with sub-wavelength precision. Our sensors translate this control into measurable signals for three high-impact domains.
Where Our Sensors Make a Difference
Biomedical Sensing
Plasmonic metasurfaces detecting disease biomarkers — proteins, nucleic acids, exosomes — at femtomolar concentrations without fluorescent labels. Target applications include early-stage cancer screening, infectious disease diagnostics, and point-of-care testing.
Environmental Monitoring
Miniaturised metasurface chips integrated into field-deployable platforms detect heavy metals, persistent organic pollutants, and microplastics in water and soil. Multiplexed arrays enable simultaneous multi-analyte profiling for regulatory compliance monitoring.
Gas Sensing
Mid-infrared metasurfaces with engineered vibrational resonances achieve ppb-level detection of trace gases — VOCs, CO₂, NOₓ, NH₃ — via surface-enhanced infrared absorption spectroscopy (SEIRA). Chip-scale form factor suits industrial safety monitors, breath analysis, and indoor air quality systems.
From Simulation to Fabricated Sensor
Computational Design
Full-wave FDTD and RCWA simulations guide unit-cell geometry — shape, pitch, height — to place resonances precisely where the target analyte absorbs or scatters.
Maskless Nanofabrication
Tuo Tuo UV and 3D lithography platforms allow rapid design iteration without physical masks, shortening design-to-chip cycles from weeks to days.
Surface Functionalisation
Thiol-based SAMs and aptamer chemistry provide analyte specificity while maintaining electromagnetic coupling between the recognition layer and the metasurface near-field.
Optical Characterisation
3D confocal and white-light interferometry microscopes quantify surface quality; spectroscopic ellipsometry and FTIR confirm resonance positions against design targets.
Sensor Integration & Validation
Chips are packaged into microfluidic or gas-cell housings and benchmarked against clinical or regulatory reference standards before transfer to application partners.
