Abstract: Nanomechanical resonators enable the measurement of mass with extraordinary sensitivity. Resolving small mass changes requires the resonator to be light and to ring at a very pure tone—that is, with a high quality factor. In solution, viscosity severely degrades both of these characteristics, thus preventing many applications in nanotechnology and the life sciences where fluid is required. My lab has addressed this problem by placing the solution inside a hollow resonator that is surrounded by vacuum. This eliminates signal degradation from viscous drag and has enabled us to weigh individual particles down to the attogram scale.
In this talk I will show how my lab has been using this approach to weigh individual cells in order to measure cell growth with unprecedented precision, thereby enabling new phenomena to be revealed about the interplay between cell cycle progress and cell growth dynamics. I will also highlight collaborations with physician scientists at DFCI where we are using high precision single-cell biophysical properties such as mass and density to infer treatment response of the patient.
