Routine and timely sub-picoNewton force stability and precision for biological applications of atomic force microscopy.
Force drift is a significant, yet unresolved, problem in atomic force microscopy (AFM). We show that the primary source of force drift for a popular class of cantilevers is their gold coating, even though they are coated on both sides to minimize drift. Drift of the zero-force position of the cantilever was reduced from 900 nm for gold-coated cantilevers to 70 nm (N = 10; rms) for uncoated cant...
متن کاملAtomic force microscopy with sub-picoNewton force stability for biological applications.
Atomic force microscopy (AFM) is widely used in the biological sciences. Despite 25 years of technical developments, two popular modes of bioAFM, imaging and single molecule force spectroscopy, remain hindered by relatively poor force precision and stability. Recently, we achieved both sub-pN force precision and stability under biologically useful conditions (in liquid at room temperature). Imp...
متن کاملSol-Gel Synthesis, Characterization and Optical Properties of Bi 3+ - Doped CdO Sub-Micron Size Materials
Highly crystalline Bi3+-doped cadmium oxide (CdO) sub-micron structures were synthesized by calcination the obtained precursor from a sol-gel reaction. The reaction was carried out with cadmium nitrate (Cd(NO3)2.4H2O), bismuth nitrate (Bi(NO3)3.5H2O) and ethylene glycol (C2H6O2) reactan...
متن کاملThree-dimensional quantitative force maps in liquid with 10 piconewton, angstrom and sub-minute resolutions.
We develop a bimodal force microscopy method to map the three-dimensional force fields and their time-evolution on a variety of solid-water interfaces. The force maps show an oscillatory decaying force perpendicular to the solid surface with a 0.3 nm periodicity. The technique enables the three-dimensional imaging and mapping of the hydration layers and forces on mica and protein GroEL surfaces...
متن کاملDetection of Resistive Shorts in Deep Sub-micron Technologies
Current-based tests are the most effective methods available to detect resistive shorts. Delta IDDQ testing is the most sensitive variant and can handle off-state currents of 10-100 mA of a single core. Nevertheless this is not sufficient to handle the next generations of very deep sub-micron technologies. Moreover delay-fault testing and very-low voltage testing are not a real alternative for ...
