What is a Probe in Nanotechnology?
In the context of
nanotechnology, a probe typically refers to a device or instrument used to measure or manipulate nanomaterials at the atomic or molecular scale. These probes are crucial for various applications, ranging from scientific research to industrial processes. They enable scientists to observe, manipulate, and measure
nanoscale phenomena with high precision.
Types of Probes
There are several types of probes commonly used in nanotechnology: Scanning Tunneling Microscope (STM): Utilizes quantum tunneling to generate images of surfaces at the atomic level.
Atomic Force Microscope (AFM): Measures the force between a sharp probe and the surface to generate high-resolution topographic maps.
Optical Probes: Use light to interact with nanomaterials, often employed in
spectroscopy techniques.
Electrical Probes: Measure electrical properties such as
conductivity and resistance at the nanoscale.
