Nanotoxicology skill for in vitro cytotoxicity assessment and cell viability analysis

General

What this skill does


# Cytotoxicity Assay Analyzer

## Purpose

The Cytotoxicity Assay Analyzer skill provides comprehensive in vitro toxicity assessment of nanomaterials, enabling systematic evaluation of cell viability, determination of safe exposure levels, and identification of toxicity mechanisms.

## Capabilities

- MTT/MTS/WST assay analysis
- Live/dead staining quantification
- IC50/EC50 calculation
- Dose-response curve fitting
- Cell morphology analysis
- Apoptosis/necrosis detection

## Usage Guidelines

### Cytotoxicity Assessment

1. **Assay Selection**
   - Choose appropriate viability assay
   - Consider nanoparticle interference
   - Include proper controls

2. **Data Analysis**
   - Calculate percent viability
   - Fit dose-response curves
   - Determine IC50/EC50

3. **Result Interpretation**
   - Compare to benchmark materials
   - Assess mechanism of toxicity
   - Report with appropriate context

## Process Integration

- Nanomaterial Safety Assessment Pipeline
- Nanoparticle Drug Delivery System Development
