Yes, tungsten needles can be used for microscale particle manipulation. In particular, tungsten needles can be used for the precise manipulation of individual or small groups of particles in microfluidic devices. Tungsten needles are strong and durable, and their small size allows for precise positioning and manipulation of particles. Additionally, tungsten needles can be surface-modified to alter their surface properties, such as wettability and surface charge, which can further improve their ability to manipulate particles in microfluidic systems. Overall, tungsten needles are a useful tool for microscale particle manipulation in a variety of applications, including microfluidics, nanotechnology, and materials science.
