According to recent research published in the journal Nano Letters, "The photoluminescence of CdSe/Cds core/shall quantum dots, nanorods, and tetrapods is investigated as a function of applied hydorstatic and non-hydrostatic pressure. The optoelectronic properties of all three nanocrystal morphologies are affected by strain."
"Further more, it is demonstrated that the unique morphology of seeded tetrapods is highly sensitive to non-isotropic stress environments. Seeded tetrapods can thereby serve as an optical strain gauge, capable of measuring forces on the order of nanonewtons," wrote C.L. Choi and colleagues, University of California.
