Researchers develop new ultrasensitive assay to detect most poisonous substance known

Scientists at City of Hope and the California Department of Public Health have developed a new ultrasensitive assay to detect botulinum neurotoxin. The toxin is one of the most poisonous substances known that can cause life-threatening disease, and is considered a major potential bioterrorism threat agent. The research team’s work is published today in the online journal PLoS ONE.
