Making gold nanoparticles (AuNP) is both costly and dangerous. AuNP are used in many areas of modern technology, ranging from high precision electronics to cancer imaging and therapies. Due to their targeted aggregation and biosafety, they exhibit impressive properties improving a variety of medical technologies. By using algae to accrue gold and then pack it into nanoparticles, we can avoid the issues with their development, while attempting to maintain medical quality.
