For cutting edge AFM research, such as molecular imaging and dynamic force imaging, it is often critical to use probes with specific combinations of resonance frequency and force constants. The Nanonics production technology is capable of producing glass cantilevers with resonance frequencies and force constants which are extremely difficult to achieve with silicon cantilevers.

In addition, glass cantilevers have dynamic response capabilities far beyond those of silicon cantilevers. Response times of 1 micro-second are achievable, three orders of magnitude faster than the best silicon cantilevers. Such response times can monitor a variety of dynamic events including protein conformational dynamics.
