Biological sensors often display high sensitivity, selectivity, and low false alarm rates while being fabricated and operated in dirty, noisy natural environments. Attempts to emulate these sensors synthetically have not fully met expectations. Recent evidence suggests that some biological sensors exploit nontrivial quantum mechanical effects to produce macroscopic output signals. Examples of such sensors include the highly efficient energy transfer properties of photosynthesis in plants, bacteria, and algae; magnetic field sensing used by some birds for navigation; and the ability of some animals to detect odors at the single molecule level.
Service members need constant supplies of clean water, food, medicines, and materials to complete their missions. BTO is enabling the migration of biotechnology from the lab into the field, creating new opportunities to harden operations against disruption by increasing operational resilience and logistic security.
