In vitro studies refer to experiments conducted in a controlled environment outside a living organism, such as in petri dishes or test tubes. These studies are essential for understanding the fundamental properties of nanomaterials, such as their toxicity, stability, and interactions with biological molecules.
Advantages of In Vitro Studies 1. Controlled Environment: In vitro studies offer a highly controlled environment, allowing precise manipulation of experimental conditions. 2. Cost-effective: These studies are generally less expensive compared to in vivo studies. 3. Ethical Considerations: In vitro studies often bypass the ethical issues associated with animal and human testing.
Limitations of In Vitro Studies 1. Lack of Complexity: These studies cannot replicate the complex interactions that occur within a living organism. 2. Scalability Issues: Results obtained in vitro may not always be scalable to real-world applications.
