Scanning Electrochemical Microscopy (SECM): Fundamentals and Applications in Life Sciences

In recent years, scanning electrochemical microscopy (SECM) has made significant contributions to the life sciences. Innovative developments focusing on high-resolution imaging, developing novel operation modes, and combining SECM with complementary optical or scanning probe techniques renders SECM an attractive analytical approach. This chapter gives an introduction to the essential instrumentation and operation principles of SECM for studying biologically-relevant systems. Particular emphasis is given to applications aimed at imaging the activity of biochemical constituents such as enzymes, antibodies, and DNA, which play a pivotal role in biomedical diagnostics. Furthermore, the unique advantages of SECM and combined techniques for studying live cells is highlighted by discussion of selected examples.

Catalysis at the room temperature ionic liquid|water interface: H2O2 generation

H₂O₂ is produced at the interface between a room-temperature ionic liquid with decamethylferrocene as an electron donor and an acidic aqueous solution. The electron donor can be regenerated electrochemically.

Enzyme immobilization on silicate glass through simple adsorption of dendronized polymer–enzyme conjugates for localized enzymatic cascade reactions

Conjugation of enzymes to a dendronized polymer via bis-aryl hydrazone bonds enables simple and stable enzyme immobilisation on unmodified glass.

Co-immobilization of enzymes with the help of a dendronized polymer and mesoporous silica nanoparticles

Two enzymes were immobilized in close proximity to each other using enzyme-containing mesoporous nanoparticles and a dendronized polymer–enzyme hybrid structure.
