DelPhi
	The electrostatic field lines of TRAP---trp RNA binding attenuation protein (PDB ID: 2EXS). The blue and red colors represent the positive and negative polarities, respectively. The field lines indicate the directions of the electrostatic forces surrounding the protein.

DelPhi is a scientific application which calculates electrostatic potentials in and around macromolecules and the corresponding electrostatic energies. It incorporates the effects of ionic strength mediated screening by evaluating the Poisson-Boltzmann equation at a finite number of points within a three-dimensional grid box. DelPhi is commonly used in protein science to visualize variations in electrostatics along a protein or other macromolecular surface and to calculate the electrostatic components of various energies.^[1]
