By Hanna Geissler & Zesha Saleem Scientists believe that a device that uses nanoscopic needles to either inject or extract a sample from a living cells is a breakthrough forcancer research. Normally, methods used to study single cells usually lead to the cell being destroyed. However, this time, the “nanopipette” gives researchers the ability to extract minute samples from a living cell – without destroying it. This allows researchers to study the same tumour cells throughout cancer treatment. Dr Lucy Stead, associate professor of brain cancer biology at the University of Leeds, where the devi…
