Photodynamic therapies, referred to as PDT, are treatments that use visible light to destroy cancerous or precancerous cells. Abnormal tissue is brought into contact with a light-activated and light-sensitive medication before it is exposed to light, triggering a chemical reaction that releases reactive oxygen species (ROS) to attack the diseased cells. In current treatments, the medication is injected into unhealthy tissue. But injection only works if tumours are on or under the skin, such as skin cancers.<\/p>\n\n\n\n

In current treatments, the medication is injected into unhealthy tissue. But injection only works if tumours are on or under the skin, such as skin cancers. The research team found a way around the limitation, so phototherapies can be used to treat other types of cancers as well.<\/p><\/blockquote>\n\n\n\n

Thanks to silica nanoparticles doctors can use near-infrared (NIR) light, which penetrates further down into the tissue. The nanoparticles convert NIR light into visible light, triggering a chemical reaction and releasing ROS. \u201cIt\u2019s like we\u2019ve reinforced the capsule that transports the treatment for diseased cells and increased the versatility of PDT. This nano superhero is stronger and more effective, even inside the body,\u201d explained Professor Vetrone, referring to the cover illustration<\/a> depicting the team\u2019s discovery.<\/p>\n\n\n\n

Developed by a team of chemists, magnetic resonance imaging (MRI) experts, and an oncologist, the new way of selectively enveloping light-sensitive medication in a nanocapsule could be beneficial for diagnosis and treatment. \u201cEventually, nanocapsules will help us expand the scope of application,\u201d added the professor.<\/p>\n\n\n\n

Next, the team plans to test the nanoparticles in an in-vivo setting.<\/p>\n\n\n\n


About the study<\/strong><\/h3>\n\n\n\n

The research began in 2014 in collaboration with Xu Li, adjunct professor at INRS, senior scientist at the Institute of Materials Research and Engineering, and assistant adjunct professor at the National University of Singapore. Miao Wang, INRS PhD student under the joint supervision of INRS professors Vetrone and Rosei, is the lead author of \u201cOne pot synthesis of theranostic nanocapsules with lanthanide doped nanoparticles\u201d<\/a>.<\/p>\n\n\n\n
