Compact solid state pulsed power architecture for biomedical workflows: Modular topology, programmable pulse output and experimental validation on Ex vivo platelet activation

Abstract

We describe a system based on a Marx generator approach using all solid state components in a modular topology that enables higher voltages by simply adding more modules. This novel system maximizes parameter flexibility, including electric pulse amplitude, duration and repetition rate. Example of pulses generated by this all solid state generator of ∼20 kV/cm, ∼ 600 ns pulse width, and more than 300 A per pulse are shown to activate platelets by stimulating human PRP (platelet rich plasma) in a 2 mm cuvette. Two growth factors released during platelet activation were identical whether nsPEFs (nanosecond pulsed electric fields) or bovine thrombin, the standard clinical platelet activator, was used. Future in vivo studies will assess the effectiveness of nsPEFs activated platelet gels compared to those activated by bovine thrombin.
