Standing square-wave chronoamperometry (SSWCA) was applied to the analysis of the microfluid flow generated by the movement of the appendages of the Crustacea Daphnia. This novel approach provided for the first time real-time assessment and analysis of the breathing rate/fluid flow of individual organisms. An electrochemical tracer was delivered into the fluid inflow of the organism and a carbon fiber microelectrode placed in the fluid outflow's path.

- Ferrous cytochrome c does not bind ligands like cyanide and CO, leading to a study using cyclic voltammetry to determine its redox potential (-240 mV vs SHE).
- The binding constant for cyanide to reduced cytochrome c was estimated to be 4.7 x 10(-3) L M(-1), indicating that it's significantly less favorable than in ferricytochrome c due to an enthalpic barrier.
- The investigation revealed that the main issue with cyanide binding to ferrous cytochrome c is related to its compact structure and decreased conformational flexibility, influenced by various biophysical factors.
