Does anyone know about deflection sensitivity correction factor?

For force spectroscopy experiments with AFM, it is needed to calibrate the deflection sensitivity and spring constant of the cantilever. First I determine the deflection sensitivity very...

Is it possible to measure the contour length of features from an image?

I am imaging DNA using AFM. I extracted the gray scale intensity values from the image into a matrix of integer elements. Then I wrote a code in C++ to count pixels falling within a certain...

Can someone suggest the best way to immobilize single stranded DNA and G quadruplexes on Mica for AFM imaging in water?

Other than the usual method of adding divalent cations of small ionic radii, is there any better method? I want very clean background.

What is the best vibration isolation solution for AFM?

Are the isolation tables using nitrogen or compressed air supply the best? What do you think about the active isolation platforms available from Herzan and Accurion that runs simply on electricity?

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

What kind of fluid could I use for a pitfall trap that also does not invalidate molecular testing?

Hi, I want to start testing pitfall trap to obtain ants samples, but I need to conduct molecular analysis on those insects. So, what kind of fluid can I use? Ethanol expires too early and I need...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Is there any effect of different colours of light (white, red, yellow, blue etc.) on the rate of photosynthesis? If yes, why?

Light is inevitable for the process of photosynthesis reaction. Naturally sunlight plays the vital role for this process. Light may be of different colours like white, red, yellow, blue etc....
