Yes, tungsten needles can be used for microelectrode fabrication. Tungsten has excellent electrical conductivity, making it a suitable material for microelectrodes used in various applications such as neural recordings, electrochemistry, and biosensors. Tungsten microelectrodes are also known for their high durability and resistance to corrosion, making them an ideal choice for long-term in vivo studies. The small size and high aspect ratio of tungsten needles make them useful for fine-scale electrode fabrication, which is critical in many microelectrode applications.
