Cuban engineer Melanys Benítez Pérez, originally from Havana and currently residing in Spain, has created an affordable optical sensor capable of detecting diseases and analyzing food substances. This innovative device was developed at the Public University of Navarra (UPNA), where she successfully defended her doctoral thesis. Utilizing a flat surface design enhanced with gold nanoparticles, this sensor can identify essential biomarkers in small samples of blood, saliva, or food.
The sensor is capable of detecting proteins linked to cardiovascular and neurodegenerative diseases, as well as celiac disease, and can be employed in immunological tests. Additionally, it can identify gliadin, a gluten component, which is valuable for food quality control. Unlike traditional sensors that rely on cylindrical optical fibers and tend to be costly and fragile, Benítez’s sensor is more robust, economical, and easily integrated into clinical or industrial settings.
Resilient and Cost-Effective Technology
The technology leverages a physical phenomenon known as Loss Mode Resonance (LMR)Ignacio R. Matías Maestro and Abián Bentor Socorro Leránoz from UPNA’s Smart Cities Institute (ISC), is the culmination of years of dedication within the Sensors research group.
A Promising Future in Diagnostics
At just 31, Benítez began her career at Havana's Center for Genetic Engineering and Biotechnology, focusing on medical imaging. She later moved to Spain, where she completed a master's in Biomedical Engineering and a doctorate in Communications Technology, Bioengineering, and Renewable Energies. During her academic journey, she participated in international conferences, published scientific papers, and conducted research in the Netherlands.
Benítez envisions her technology being implemented in accessible diagnostic systems for medical centers, laboratories, and food companies, providing a precise, fast, and versatile tool for various needs. Her success story is part of a broader narrative of young Cuban women making strides in the scientific community.
Spotlight on Cuban Scientists
Sabrina González Pasterski, a Cuban-American theoretical physicist born in Chicago in 1993, has been hailed by Harvard University as "the next Albert Einstein." Beyond her scientific achievements, she advocates for women and girls in STEM fields (science, technology, engineering, and mathematics).
The platform Alas Tensas highlighted González in 2024 for her contributions as a predoctoral candidate in Chicago, Illinois, and her efforts to promote women in science and technology. González uses her influence to support initiatives like "Let Girls Learn," encouraging girls worldwide to pursue STEM education. She has participated in high-profile events, including a White House visit to discuss breaking gender barriers in scientific education.
González proudly identifies as a first-generation Cuban-American and is recognized as a leading figure in modern physics and a tireless advocate for gender equality in scientific access.
