Weighing molecules with light | The Royal Society

Join us for the Royal Society Clifford Paterson Prize Lecture delivered by Professor Philipp Kukura FRS. The Clifford Paterson Medal and Lecture 2026 is awarded to Professor Philipp Kukura FRS for pioneering and democratising mass photometry, a novel means of mass measurement for single biomolecules. Professor Kukura will cover how the development and use of scales was critical to trade, the creation of money and thus the development of human society. Weight and mass are used somewhat interchangeably for day-to-day objects, but need to be differentiated as objects become smaller and smaller. Once we reach scales much smaller than the width of human hair, gravity is no longer the dominant force experienced by objects and can thus not be used to quantify objects by ‘weighing’ them. Instead, we need to measure their mass, which corresponds to the amount of matter in an object. Due to the difficulty of operating on the microscopic scale, only a very small number of methods have been developed to measure the mass of molecules over the past century. Professor Kukura will describe the development of mass photometry – a method that measures the mass of molecules and viruses by shining light at them, effectively ‘looking at them’. Professor Kukura will explain the principles of operation, and show how this technique is being used broadly in academia and industry to understand the basis of disease and aid in the development of next generation therapeutics. The Royal Society is a Fellowship of many of the world's most eminent scientists and is the oldest scientific academy in continuous existence. https://royalsociety.org/ Subscribe to our YouTube channel for exciting science videos and live events.    / royalsociety   Find us on: Bluesky: https://bsky.app/profile/royalsociety...
