On page 2945, R. H. Goldsmith and co‐workers describe an all‐glass, high‐Q, low‐mode‐volume optical microresonator for label‐free sensing and imaging, which overcomes scalability barriers and also brings other advantages, including optical transparency. By using the microresonators as transducers to detect heat dissipated by individual nano‐objects upon photoexcitation, label‐free single‐particle imaging is demonstrated.
