What are Nanosensors?

Nanosensors are miniature devices that detect and respond to physical or chemical changes at the nanoscale level. These sensors utilize nanotechnology to provide highly sensitive and accurate measurements. They can detect various parameters such as temperature, pressure, chemical composition, and biological molecules.

Understanding AFM Tips

Atomic force microscopy (AFM) is a powerful imaging technique used to study surfaces at the atomic level. AFM tips, also known as probes or cantilevers, are the critical components of AFM instruments. They are incredibly sharp tips made of materials like silicon or silicon nitride. These tips scan the surface of the sample, and the interaction forces between the tip and the sample are used to create high-resolution images.
