Breaking Barriers in Photothermal Tumor Therapy: A Cascade of Strain-Engineered Nanozyme in Action

Cancer, a deadly and constantly evolving disease, has always been difficult to treat due to the complexity of the tumor microenvironment (TME). Cancer nanomedicines are proving to be a much better alternative for treatment due to their stability and ability to provide an efficient targeted therapy. An amorphous alloy bimetallene with an introduction of 2 % tensile strain with photothermal multiple enzyme-like catalytic activity is being presented here that functions as a TME-responsive nanozyme. Labeled as RhRu, this bimetallene, under acidic conditions, functions as oxidase (OXD) - like, peroxidase (POD) - like and catalase (CAT) - like enzymes, by producing radicals and disrupting the tumor cells. This effect is enhanced especially upon irradiation of laser and introduction of tensile strain in its heterophase boundaries. This current highlight discusses the strain engineering tactic of la-RhRu bimetallene and its potency as an anti-tumor therapeutic.
