A method to confront computer simulations to real nature is reported. "Experimental" results calculated from the simulation are analyzed through the same model as the actual experiments. The same terms are thus used to describe the simulated and the real sample; they can then be compared, with some reliability, to one another and also to the corresponding quantities obtained directly from the microscopic information provided by the simulation. The method is applied to neutron diffraction experiments performed on orientationally disordered neopentane (C(CD3)4) single crystals, a system for which a realistic molecular dynamics simulation has also been performed. Our method turns out to be a severe test both for the simulation and the models used to interpret the experiments.

Simulation Based

Modeling and simulation is another way of finding the interaction between different drugs and chemical species with human cell. Preliminary studies before clinical trial involve computer simulation based on the physical modeling so that clinical trial can be made easier. In many aspects of drug developing, simulation is an essential tool. Here molecular dynamics simulation is performed for the interaction of the spike protein of Covid-19 virus and some of the recently used drugs. Also, the effect of caffeine, theanine, nicotine etc on the virus is found by simulation

Drug And Gene Delivery

Lysine dendrimers and dendrigrafts are often used in biomedicine for drug and gene delivery to different target organs or cells. In present paper the possibility of complex formation by lysine dendrigraft and 16 molecules of therapeutic KED peptide was investigated using molecular dynamics simulation method. A system containing of one dendrigraftt and 16 KED peptides in water were studied. It was shown that stable complex consisting of the dendrigraft and the peptide molecules formed and structure of this complex was studied. Similar complexes could be used in future for delivery of other therapeutic peptides to target organs.
