Researchers in the UK have developed a new technique that could make light-based cancer treatment more effective and safer for patients while reducing its cost.
About:
Light-based or photo-dynamic therapy is already a clinically-approved treatment, which uses drugs that only work when exposed to light to destroy cancer cells.
However, many of these drugs are frequently toxic even without light, causing many side effects in patients and leading to treatment failure.
Now, researchers in the UK have sought to improve these drugs by using small carbon dots as a way to get the drug to the tumour.
Carbon dots are fluorescent nanoparticles with very little toxicity, making them extremely useful for this application.
