The challenges in the use of carbon nanotubes (CNTs) for biomedical applications primarily revolve around scalability, competition with other materials, and environmental concerns.
Scalability: One of the significant challenges is the production of CNTs on a large scale. Despite their unique thermal, electrical, and mechanical properties, the synthesis of CNTs and other carbon nanomaterials remains a complex process, particularly when scaled up. The chemical vapor deposition (CVD) method, while effective, requires further optimization to achieve efficient large-scale production without compromising the quality and properties of the CNTs. This is crucial for biomedical applications where consistency and reliability are paramount.
Competition with Other Materials: CNTs face stiff competition from other conductive carbon materials such as carbon black, chopped carbon fibers, and graphene. Each of these materials offers different combinations of properties that may be more suitable for specific applications. For instance, carbon black has higher CO2 emissions per kilogram but might be preferred due to its lower cost or higher availability. Graphene, despite its production challenges, offers superior electrical conductivity and strength. Therefore, the adoption of CNTs in biomedical applications is not just about their intrinsic properties but also about their comparative advantages and cost-effectiveness.
Environmental Concerns: The environmental impact of CNTs production and use is another critical challenge. The production processes of CNTs and competing materials like graphene can be energy-intensive and may require harsh chemicals, leading to environmental concerns. For example, the "top-down" production method of graphene is known to be energy inefficient and water-intensive. Additionally, the release of nanoparticles from materials like CNTs into the environment, as observed in tire studies, raises questions about their long-term environmental impact, especially in biomedical applications where materials may come into direct contact with biological systems.
In summary, while CNTs offer promising properties for biomedical applications, their widespread use is hindered by challenges related to scalability, competition with other materials, and environmental concerns. Addressing these issues through technological advancements and sustainable practices will be crucial for the future of CNTs in the biomedical field.
