Heat flux measurement shows potential for the early detection of infectious growth. Our research is motivated by the possibility of using heat flux sensors for the early detection of infection on aortic vascular grafts by measuring the onset of bacterial growth. Applying heat flux measurement as an infectious marker on implant surfaces is yet to be experimentally explored. We have previously shown the measurement of the exponential growth curve of a bacterial population in a thermally stabilized laboratory environment. In this work, we further explore the limits of the microcalorimetric measurements via heat flux sensors in a microfluidic chip in a thermally fluctuating environment.
热通量测量显示出早期检测感染的潜力。我们的研究受到了使用热通量传感器来检测主动脉血管移植物感染的启发,通过测量细菌生长的开始来实现这一目标。在植入物表面应用热通量测量作为感染标志物尚未在实验中进行探索。我们之前已经展示了在热稳定的实验室环境中测量细菌群体的指数生长曲线。在这项工作中,我们通过在热波动环境中的微流控芯片中的热通量传感器进一步探索了微热量计测量的极限。
