Gold nanodots can help boost cancer cell response to ultrasound treatment

Cells have surface receptors called integrins that bind to repetitive domains present on the extracellular matrix (ECM) surrounding the cells, allowing them to grow and spread. A new study from the Department of Bioengineering (BE), Indian Institute of Science (IISc) and collaborators shows that tweaking the spacing between these binding domains on the ECM can boost the efficiency of ultrasound treatment applied to kill cancer cells.
