Tungsten needles can be used for microinjection in biological applications. Tungsten needles can be fabricated with sharp tips that are suitable for piercing cell membranes and delivering material into cells, making them a popular choice for microinjection applications. Tungsten needles are also biocompatible and have low toxicity, which makes them a suitable option for biological applications. They are often used for injecting DNA, RNA, and other biomolecules into cells for genetic engineering and gene therapy research.
