Designing, construction and analysis of line-scanning detection instrument for photonic crystal enhanced fluorescence
… and analysis of a portable line-scanning detection instrument for photonic crystal enhanced fluorescence. In order to increase the fluorescence signal for low-concentration detection, we introduced the photonic crystal enhanced fluorescence detection modality and demonstrated that it is a …

External cavity laser label-free biosensor
… high sensitivity, large dynamic range and simple detection instrumentation. The photonic crystal is fabricated inexpensively from plastic materials, and its resonant wavelength is tuned by adsorption of biomolecules on its surface. Gain for the lasing process is provided by a semiconductor optical …

Sensitive microarray-based biomarker detection using photonic crystal enhanced fluorescence and label-free imaging
Fluorescence-based biomarker detection in serum, saliva, urine, or breath condensate samples holds great promise for disease diagnostics and therapy monitoring because of its non-invasive nature. The microarray format, for its high-throughput and low analyte consumption characteristics, is …

Highly sensitive biosensors using photonic crystal enhanced fluorescence
… PCEF to multiplexed microspot immunoassays for detection of allergen-specific antibodies. The PCEF system was able to detect low concentrations of Fel d1 specific IgE ~0.02 kU/L, which is 5-fold to 17-fold more sensitive than the commercially available FDA-approved analyzers. We also aimed to …

Crisp and Fuzzy Signal Detection Theory and Pilot Weather Judgment: Implications for VFR Flights Into IMC
… to visual flight rules (VFR) flight into instrument meteorological conditions (IMC). The situation assessment hypothesis suggests that pilots may inadvertently enter IMC because they lack the sensitivity needed to distinguish between visual meteorological conditions (VMC) and IMC. An …
