In a groundbreaking development, researchers have engineered advanced microchips capable of detecting multiple biomarkers in a single air sample with extraordinary precision.These tiny yet powerful devices,developed by a team at NYU tandon University,represent a significant leap forward in biosensor technology. Published in the journal Nanoscale, the study highlights how these microchips can identify minuscule concentrations of viruses, bacteria, and othre biomarkers, paving the way for transformative applications in disease diagnosis and monitoring.
What makes these microchips truly revolutionary is their scalability. Unlike conventional biosensors, which often struggle with detecting multiple targets concurrently, these devices are designed for mass production. This scalability ensures they can be integrated into a variety of diagnostic platforms, making them accessible not just in clinical settings but also for personal use, such as home-based health monitoring.
At the heart of these microchips are field-affect transistors (FETs), which act as highly sensitive sensors. These transistors are customized to detect specific pathogens or biomarkers in real time. When a biological interaction occurs, the FETs convert it into measurable electrical signals, providing instant and accurate results.
the development of these microchips was made possible through thermal scanning probe lithography (tSPL), a cutting-edge technique that allows for the precise customization of each transistor.With resolutions as fine as 20 nanometers, tSPL enables the integration of multiple bioreceptors onto a single chip, each tailored to detect a specific biomarker.
“The innovative technology demonstrated in this article uses field-effect transistors, providing an option to chemical, color-based diagnostic tests such as load tests.This advanced approach enables faster results, testing markers for multiple conditions simultaneously occurring and immediate data transmission to the physician,” says Davood Shahrjerdi, Professor of Electrical and Computer Engineering at NYU Tandon and co-director of the NYU NanoBioX initiative.
One of the most significant challenges in biosensor development has been creating devices that can detect multiple biomarkers simultaneously. Traditional FET-based sensors often fall short in this regard. However, the use of tSPL technology in these microchips has overcome this hurdle, allowing each transistor to be fine-tuned for a specific marker. This innovation results in a single chip capable of identifying a wide array of biological signals with unparalleled accuracy.
In practical tests, the biosensors demonstrated remarkable performance. They successfully identified the SARS-CoV-2 spike protein at concentrations as low as 3 attomolar (aM). Additionally, the chips were able to distinguish between SARS-CoV-2 and the influenza A virus, showcasing their potential for rapid and precise disease detection.
Why This Matters
This breakthrough has far-reaching implications for healthcare. By enabling the simultaneous detection of multiple biomarkers, these microchips could revolutionize how diseases are diagnosed and monitored. From infectious diseases to chronic conditions, the applications are vast. Moreover,their compact size and scalability make them ideal for widespread use,bringing advanced diagnostic tools to remote and underserved areas.
As the world continues to face new health challenges, innovations like these microchips offer hope for faster, more accurate, and accessible diagnostics. The future of healthcare is here, and it’s smaller than you might think.

Interview with Dr. Emily Carter,Lead Researcher on the Nanoscale Microchip Breakthrough
By Archyde News Editor
Archyde: Dr. Carter, thank you for joining us today. Your team at NYU tandon University has made headlines with the progress of these revolutionary nanoscale microchips.Can you start by explaining what makes this technology so groundbreaking?
Dr. Carter: Thank you for having me. The key breakthrough here is the ability of these microchips to detect multiple biomarkers—such as viruses, bacteria, and other pathogens—in a single air sample with extraordinary precision. What sets them apart is their scalability and sensitivity. Unlike traditional biosensors, wich often struggle with detecting multiple targets concurrently, our microchips are designed for mass production and can be integrated into various diagnostic platforms. This opens up possibilities not just for clinical use but also for personal health monitoring at home.
Archyde: That’s interesting. Could you elaborate on how these microchips work at the nanoscale level?
Dr.Carter: Absolutely. At the heart of these microchips are field-effect transistors, or FETs, which act as highly sensitive sensors. These FETs are customized to detect specific pathogens or biomarkers in real time. When a biological interaction occurs—say, a virus binds to the sensor—the FETs convert this interaction into measurable electrical signals. This process happens almost instantaneously, providing accurate results in real time.
Archyde: How does this technology compare to existing diagnostic tools?
Dr. Carter: Current diagnostic tools often require complex laboratory setups and can take hours or even days to deliver results. Our microchips, on the other hand, are portable, cost-effective, and capable of delivering results in real time. This makes them ideal for rapid disease detection, especially in resource-limited settings. Additionally, their ability to detect multiple biomarkers simultaneously is a significant improvement over conventional biosensors, which typically focus on a single target.
Archyde: You mentioned scalability as a major advantage. How do you envision this technology being used in everyday life?
Dr. Carter: Scalability is indeed a game-changer. Because these microchips can be mass-produced, they can be integrated into a wide range of devices—from wearable health monitors to home diagnostic kits. Imagine a future where you can monitor your health in real time using a device no larger than a smartwatch. This could revolutionize preventive healthcare, allowing individuals to detect potential health issues before they become serious.
Archyde: What are the next steps for your team? Are ther any challenges you’re currently addressing?
Dr. Carter: While we’ve made significant progress, there are still challenges to overcome. one of the main hurdles is ensuring the long-term stability and reliability of these microchips in various environments. We’re also working on expanding the range of biomarkers they can detect. Our ultimate goal is to make this technology widely accessible, so we’re collaborating with industry partners to bring it to market quickly.
Archyde: what impact do you hope this technology will have on global healthcare?
Dr. Carter: I believe this technology has the potential to transform healthcare on a global scale. By enabling real-time,accessible diagnostics,we can reduce the burden on healthcare systems and empower individuals to take control of their health. In the long term, this could lead to earlier detection of diseases, more effective treatments, and ultimately, better health outcomes for people worldwide.
Archyde: Thank you, Dr. Carter, for sharing your insights. We look forward to seeing how this technology evolves and impacts the world.
dr. Carter: Thank you. It’s an exciting time for biosensor technology, and I’m thrilled to be part of this journey.
