Originální abstrakt

Microcalorimeters have been widely used for characterizing molecular interactions in physical, chemical and biological research. Here, we report on a droplet-based micromachined calorimeter for real-time energy balance monitoring. The microcalorimeter was fabricated by a single lithography process and wafer dicing using glass substrate with a diameter and a thickness of approximate to 100 mm and approximate to 100 mu m, respectively. The sample with volume of approximate to 0.5 mu L was placed on the microcalorimeter and covered with mineral oil to avoid evaporation. The microcalorimeter was operated in differential mode having the temperature and power resolution of approximate to 148 mu k and approximate to 42 nW, respectively. With this system, we monitored the energy balance of H2O2 decomposition catalyzed by few self-propelled Pt microrobots. Such a simple microcalorimeter has tremendous potential for chemical and biological research such as monitoring the energy balance of living cells or microorganisms and correlating the energy changes with their activities and status.
