 This study proposes a novel approach to controlling human neuroblastoma cells using light pulses. A semi-transparent polymer film was used as a platform for the cells, which were then exposed to light pulses. This resulted in a decrease in cell proliferation, suggesting that light pulses could be used to manipulate the cell's behavior. Additionally, the researchers found that the light pulses caused an increase in intracellular calcium levels, indicating that the cells were responding to the light pulses. These findings suggest that this platform could be used to monitor and control the behavior of living cells, potentially leading to applications in biosensing and biomedical treatments.
