Educating Brazil's Nanotechnology Workforce
Bridging the gap between industry demands and university offerings in the nanoscale revolution
Brazil's Nano-Ambition: The Nanometric Challenge
In the universe invisible to the naked eye, where materials transform into structures billions of times smaller than a meter, lies a technological revolution promising to reshape industrial sectors from medicine to energy, materials to computing. This is the promise of nanotechnology—the ability to manipulate matter at atomic and molecular scales to create materials and devices with extraordinary properties.
In Brazil, this emerging field represents not just a scientific frontier but an urgent educational challenge: how to train a generation of professionals equipped to meet the demands of an industry still taking shape, while advancing cutting-edge research?
The world is estimated to need more than one million professionals specialized in nanoscience and nanotechnology (N&N) in the next decade, each requiring interdisciplinary training combining physics, chemistry, biology, engineering, and materials science 1 . In the Brazilian context, this need clashes with persistent educational realities—regional inequalities, outdated curricula, and a historical disconnect between academia and industry.
Workforce Challenge
Brazil faces the dual challenge of training specialized professionals while building the industrial ecosystem to employ them.
Success Stories
Cases like Nanox, a spin-off from UFSCar that became a global leader in microbiological control, demonstrate Brazil's latent potential 2 .

The Ideal Brazilian Nanotechnologist Profile
"Brazilian managers consider social skills and innovation as critical as—if not more than—pure technical competencies. However, performance in all areas falls significantly below assigned importance, with gaps ranging from 1.47 to 2.07 points 4 ."
These gaps represent critical challenges for training nanotechnology professionals. The data reveals that the most significant discrepancies occur precisely in the areas deemed most important by industry leaders.
Academic Training Ground: Nurturing Nano-Talents
Educational strategies in Brazilian nanolaboratories and universities
Brazilian higher education institutions have explored various strategies to incorporate N&N topics into their curricula, from creating terminal areas in traditional science and engineering programs to offering new academic programs at undergraduate and graduate levels dedicated to nanotechnology 1 .
A notable example is the Center for Development of Functional Materials (CDMF) at UFSCar, which gave rise to Nanox—Brazil's first nanotechnology company 2 . Founded in 2004 as a spin-off from CDMF, Nanox represents the triple helix model (university-industry-government) in action.

Educational Challenges
Inherent Complexity
The subject is inherently complex and characterized by dense terminology. Additionally, the nanoscale dimension introduces unique dissemination difficulties.
Visualization Challenges
Materials at this scale are only observable with highly sophisticated instruments, requiring the public to understand concepts of objects they cannot directly see 1 .
Poor Social Perception
Social perception of nanotechnology is poor, as corroborated by various studies, indicating a significant need for more efforts to improve this perception 1 .
Structural Educational Inequalities
In Brazil, students from the richest 20% of the population are approximately twice as likely to complete high school compared to the poorest 20% 5 .
A Crucial Experiment: Characterizing Nanomaterials with TERS
Tip-Enhanced Raman Spectroscopy advances nanomaterial analysis in Brazil
To understand advances in Brazilian nanotechnology, it is instructive to examine a cutting-edge characterization technique that has driven significant discoveries: Tip-Enhanced Raman Spectroscopy (TERS). This technique combines the power of Raman spectroscopy with the nanometric resolution of atomic force microscopy, allowing chemical characterization of materials with spatial resolution below 10 nm.
The Porto system, developed in Brazil and commercialized by FabNS, represents a technological advance in this area. The platform was designed for micro-Raman, nano-Raman, and photoluminescence spectroscopies, incorporating a confocal optical configuration for optimized efficiency in signal collection in a completely user-customizable optical path 6 .
Step-by-Step Methodology
A typical experiment using the Porto system to characterize samples of twisted double-layer graphene—a material with extraordinary electronic properties—involves the following steps:
Sample Preparation
The material to be analyzed (in this case, double-layer graphene with specific twist angle) is deposited on a previously cleaned SiO₂/Si substrate.
TERS Tip Preparation
The patented TERS nanoantennas—which operate in resonant configuration—are mounted on the atomic force microscope holder. These tips are capable of providing unprecedented spectral enhancements 6 .
Data Acquisition
The TERS tip is positioned on the sample surface using an atomic force control system. A laser is focused on the tip region through a confocal optical system. The tip is rasterized over the area of interest while the Raman signal is collected.
Data Analysis
The PortoFlow software allows analysis of complex optical hyperspectral data interactively, without requiring the user to program a single line of code 6 .
TERS Analysis Results Across Different Materials
Scientific Impact and Recognition
Using this system, researchers from Japan, USA, Belgium, and Brazil proved it possible, for the first time, to use optics to probe the vibrational modes of a reconstructed lattice of twisted double-layer graphene, below the magic angle. This achievement earned the team the cover of Nature magazine 6 .
