Researchers in the Cao group are using Förster resonance energy transfer to study multichromophoric systems. Which of the following best describes the most significant limitation of using this technology?
W) The length scale is restrictive because of the rapid decay in force with distance
X) The donor chromophore must be particularly bright, which is typically difficult to induce
Y) The acceptor chromophore must be particularly bright, which is typically difficult to induce
Z) It generally observes a low signal-to-noise ratio
✔️Answer:Z) It generally observes a low signal-to-noise ratio
