While nanotechnology offers numerous advantages, there are also some challenges and concerns:
1. Cost: The production and application of nanomaterials can be more expensive than traditional methods. 2. Health and Safety: The long-term effects of exposure to nanoparticles are still not fully understood, raising potential health and safety concerns for workers and consumers. 3. Regulatory Issues: The use of nanomaterials in consumer products is subject to regulatory scrutiny, which can vary by region and may affect market adoption.
