A Microscopic Partnership with Macro Impact
In the invisible world of the infinitesimally small, a powerful international partnership is forming. The strategic collaboration between the United States and Brazil in nanotechnology represents one of the most promising scientific alliances of the 21st century.
Imagine particles so tiny that they're virtually invisible, yet capable of revolutionizing everything from cancer treatment to clean energy. This is the realm of nanotechnology, where materials engineered at the scale of billionths of a meter exhibit extraordinary properties.
The US-Brazil partnership in this field combines complementary strengths and shared ambitions, creating a bridge between North and South that could accelerate innovations to address some of humanity's most pressing challenges.
This collaboration brings together "powerful and complementary institutions" that can fulfill "the role of bringing the benefits of research and innovation to society" 1 .
The formal framework began with the Agreement on Science and Technology between the United States and Brazil, establishing a Joint Commission Meeting (JCM) on Scientific and Technological Cooperation 9 .
Brazil proposed nanotechnology as one of three new formal areas of bilateral engagement during a Joint Commission Meeting in Brasilia 3 . This elevation to a priority sector reflected nanotechnology's growing importance.
Then-presidents Barack Obama and Dilma Rousseff officially welcomed this development, recognizing nanotechnology's potential to drive innovation and address global challenges 6 . This high-level endorsement signaled a shared commitment.
The United States brings to this partnership a mature ecosystem of nanotechnology research and development, anchored by the National Nanotechnology Initiative (NNI) 3 .
Brazil has strategically positioned itself as a nanotechnology leader in the Global South with approximately 2,500 researchers working across national laboratories 3 .

Joint publications
Brazil's renewable energy advantage (approximately 90% of electricity from renewable sources) positions it as a potential hub for energy-intensive AI computing infrastructure 5 .
Brazil holds one of the world's largest reserves of rare earth elements, crucial for nanotechnology applications including semiconductors 5 .
Collaborative research could develop nano-enabled solutions that boost productivity while minimizing environmental impacts.
The relationship has experienced fluctuations, as evidenced by trade tensions in 2025 that led to US tariffs on Brazilian goods 5 . Scientific collaboration has proven more resilient than diplomatic relations.
Brazil's National AI Plan 2024-2028 emphasizes "sovereignty and autonomy" in technology development 5 . Successful collaboration requires frameworks that respect these sovereignty concerns.
Both nations face questions about the potential environmental and health impacts of engineered nanomaterials . Collaborative research on nanotechnology environmental health and safety (nano-EHS) can help identify potential risks and develop appropriate safety protocols.
The US-Brazil collaboration in nanotechnology represents more than just scientific cooperation—it embodies a shared commitment to harnessing cutting-edge science for economic development and social progress.
By combining American technological leadership with Brazilian research talent and natural advantages, this partnership has the potential to generate innovations that benefit not just both nations but the global community.
This collaboration between "powerful and complementary institutions" will fulfill the vital role of "bringing the benefits of research and innovation to society" 1 .
In the invisible world of the nanoscale, this partnership is building something truly monumental—a bridge between nations that promises to accelerate innovation and create a better future for citizens in both countries and beyond.
