First ‘Nanotherapeutics’ Delivered to a Tumor
May 17, 2017
(Science Daily) – For the first time, WSU researchers have demonstrated a way to deliver a drug to a tumor by attaching it to a blood cell. The innovation could let doctors target tumors with anticancer drugs that might otherwise damage healthy tissues. To develop the treatment, a team led by Zhenjia Wang, an assistant professor of pharmaceutical sciences, worked at the microscopic scale using a nanotherapeutic particle so small that 1,000 of them would fit across the width of a hair. By attaching a nanoscale particle to an infection-fighting white blood cell, the team showed they can get a drug past the armor of blood vessels that typically shield a tumor. This has been a major challenge in nanotechnology drug delivery.
