# GROMACS MD Executor

## Purpose

The GROMACS MD Executor skill provides molecular dynamics simulation capabilities specialized for nanoparticle-biomolecule interactions, enabling investigation of drug delivery systems, protein-surface interactions, and membrane penetration.

## Capabilities

- Nanoparticle-protein simulations
- Membrane-nanoparticle interactions
- Coarse-grained modeling (Martini)
- Free energy calculations
- Enhanced sampling methods
- Trajectory analysis and visualization

## Usage Guidelines

### Bio-Nano MD Workflow

1. **System Preparation**
   - Parameterize nanoparticle
   - Solvate system
   - Add ions for neutralization

2. **Equilibration**
   - Minimize energy
   - NVT equilibration
   - NPT equilibration

3. **Production and Analysis**
   - Run appropriate sampling
   - Calculate binding energies
   - Analyze interactions

## Process Integration

- Molecular Dynamics Simulation Workflow
- Nanoparticle Drug Delivery System Development
