ABSTRACT
The fascinating application of engineered nanoparticles in biomedicine inspired scientists and engineers to spare no effort in it. Many aspects of the application of nanoparticles in biomedicine have been well studied and developed in the past few decades. Optical images cooperate with different nanomaterials, where organic dyed doped nanoparticle is one type of nanomaterials that have been widely adopted in this field. The applications offer surprising results on target that doctors aim. Light-triggered cancer therapy focuses on 2 kinds of drugs that help the human body to kill cancer cells. Both photothermal therapy (PTT) and photodynamic therapy (PDT) utilise approaches as a photothermal probe to design a new cancer therapy. The use of nanomaterial-based electrochemical biosensors in biomedicine is also summarized in this review. Depending on the different characteristics of various nanoparticles, it is believed that more applications will be invented.
