The addition of aflatoxin B1 to the chirality sensor resulted in transverse CD signal compared to a blank control as shown by CD measurements. This process also allowed the rapid and facile determination of concentrations of aflatoxin B1 in drinking water (tap water). Good linearity for all calibration curves was obtained, and the limit of detection (LOD) for aflatoxin B1 was 0.02 ng/mL in tap water."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Chirality sensor and method for detection of aflatoxin by using the sensor","description":"A universal chirality sensor based on immuno-recognition-driven nanoparticle assembly has been fabricated.
