No one is immune from the possibility of heart disease. A team of scientists working in Japan has demonstrated a femtosecond laser technique that could help medical researchers test anti-fibrillation medicines on heart cells in the laboratory.
The group at Osaka University has used high-power 780-nm laser pulses to force heart tissue samples to change their beating frequency. This “optical pacemaker,” reported in Optics Express, would not work outside of the laboratory because of long-term complications, but it could test new drugs that might eventually lessen the need for pacemakers.
