Viscoelasticity describes fluids that exhibit both viscous and elastic characteristics when deformed. In nanotechnology, viscoelastic fluids can be found in polymer solutions and biological fluids. The elastic nature of these fluids can be leveraged to design nanodevices that require specific mechanical responses, such as nanosensors and actuators. Understanding viscoelastic properties is also crucial for processes like electrospinning and 3D printing at the nanoscale.
