Ca2+ signaling in trypanosomatids is an important component of energy metabolism regulation and therefore, cytosolic Ca2+ concentration is finely regulated by Ca2+ transport through the plasma membrane and Ca2+ uptake and release by intracellular org

We describe a chip calorimetric technique that allows the investigation of biological material under anoxic conditions in a micro-scale and in real time. Due to the fast oxygen exchange through the sample flow channel wall, the oxygen concentration i

We present the first silicon chip-based calorimeter with segmented-flow technology (SFT) for the study of solid and aggregated samples. Solid particles or biological aggregates up to 1.5 mm are immersed in segments of aqueous solutions. The segments

In conventional bioreactors, the assessment of metabolic heat via heat balancing is difficult. The reason is the influence of inherent variables such as power input due to stirring, environmental heat loss and evaporation. Thus, the aim of this study
