Lab-on-a-chip technology gets a heartbeat with accordion-inspired pump
Researchers have developed a novel pump for lab-on-a-chip technology that can accurately recreate the blood flow waveforms generated by the human heart. For over 25 years, lab-on-a-chip systems, also known as microphysiological systems (MPS), have enabled scientists to model human organs and blood vessels using real human cells in microscopic artificial environments. These MPS are crucial for studying various conditions, including heart disease, and for testing the efficacy of new pharmaceutical drugs. However, a significant limitation has been the inability to precisely replicate the dynamic blood flow patterns produced by the heart. The new pump, inspired by the mechanics of an accordion, addresses this long-standing challenge, potentially enhancing the accuracy and utility of these vital research tools.
The development of an accordion-inspired pump for lab-on-a-chip systems marks a significant advancement in replicating physiological conditions ex vivo. This innovation directly addresses a critical limitation in microphysiological systems, which have historically struggled to accurately mimic the pulsatile nature of human blood flow. By improving the fidelity of these models, researchers can expect more reliable data for drug development and disease research, potentially reducing the need for animal testing and accelerating therapeutic discovery. The long-term impact will likely be seen in more precise preclinical assessments and a deeper understanding of cardiovascular dynamics at the cellular level, contributing to more personalized and effective medical treatments in the coming decade.
