# NTA Particle Tracker ## Purpose The NTA Particle Tracker skill provides single-particle tracking analysis for nanoparticle size and concentration measurements, offering particle-by-particle characterization through direct visualization. ## Capabilities - Single-particle tracking - Size-concentration profiles - Fluorescence NTA mode - Real-time size distribution - Particle count and concentration - Sample heterogeneity assessment ## Usage Guidelines ### NTA Measurement 1. **Sample Preparation** - Dilute to 10^7-10^9 particles/mL - Avoid air bubbles - Use appropriate buffer 2. **Acquisition** - Optimize camera level - Set detection threshold - Record multiple videos 3. **Analysis** - Track minimum 1000 particles - Set minimum track length - Generate size-concentration plot ## Process Integration - Statistical Particle Size Distribution Analysis - Nanoparticle Drug Delivery System Development ## Input Schema ```json { "sample_id": "string", "mode": "scatter|fluorescence", "dilution_factor": "number", "capture_time": "number (seconds)", "number_of_captures": "number" } ``` ## Output Schema ```json { "concentration": "number (particles/mL)", "mean_size": "number (nm)", "mode_size": "number (nm)", "d10": "number (nm)", "d50": "number (nm)", "d90": "number (nm)", "size_distribution": {"sizes": [], "counts": []}, "particles_tracked": "number" } ```
