Introduction to Nanotechnology
Nanotechnology is a rapidly evolving field that manipulates matter on an atomic, molecular, and supramolecular scale. It has the potential to revolutionize industries ranging from medicine to electronics. As the field expands, discovering new sources of nanomaterials and techniques becomes critical. Resource Limitation: Current sources of nanomaterials may be limited or exhaustible.
Cost Reduction: New sources can reduce the cost of raw materials and production.
Enhanced Properties: New materials may offer superior properties, such as better conductivity or biocompatibility.
Sustainability: Environmentally-friendly sources can reduce the ecological impact.
Natural Sources
Researchers are examining
natural minerals,
plants, and
microorganisms as sources of nanomaterials. For instance, cellulose nanocrystals derived from plants are being studied for their strength and biodegradability.
Recycling and Waste Materials
Recycling electronic waste and other industrial by-products can yield valuable
nanomaterials. This not only provides a new source but also addresses the problem of
waste management.
