Electrochemical Shot-Noise of a Redox Monolayer

Ballistic Brownian motion of nanoconfined DNA

“…This study established a direct link between molecular electronics [33][34][35][36] , biomechanics, and electrochemistry, highlighting the potential of nanoelectrochemical measurements to complement optical trap studies on Brownian motion at a short time scale. Future work will further exploit the potential of single-electron shuttle experiment by exploring theoretical (with Q-biol) and experimental quantum shot noise measurements as a powerful way to assess asymmetry in probability of presence [37][38][39] , but also to gain additional information on motion at short time scale. Finally, the energetics of nanoconfined DNA (thermal conductivity and dissipation) will be explored.…”

Ionic fluctuations in finite volumes: fractional noise and hyperuniformity

“…6,[34][35][36]66,102,103 The ∼1/f pink noise arises in more varied electrochemical contexts than nanopores, especially near interfaces, for example in redox monolayers. 104 More generally, the advent of microscopy techniques resolving electrochemical uctuations at the single particle level 70,[105][106][107][108] means that there are increasingly more opportunities to compare experiments and theory at the microscopic level, and more contexts to understand the kinetic response of uctuations in conned or nite volumes.…”

Single-cell Electrochemical Aptasensor Array

“…Compared to other methods, EC sensors have the merits of easy operation, high sensitivity, and portability. [10][11][12][13][14][15][16][17][18][19] For example, a recent technique using rolling circle amplification with aptamers could successfully demonstrate a limit of detection (LOD) as low as 5 CTC cells in whole blood (with 200 μL of the sample used for incubation). 20 Another approach using quantum dots as sensing probe attained a LOD of 2 cells/mL in human serum.…”
