Recent advancements in biosensor technology have the potential to revolutionize the way we monitor cancer cell activity, and a new study published in ECS Sensors Plus highlights a promising approach that could have significant implications for the construction sector, particularly in the development of smart building materials.
The research, led by Ahmad Fairuzabadi Mohd Mansor from the VLSI-MEMS Research Unit at the International Islamic University Malaysia, explores the use of gold coatings on printed circuit board (PCB) and polyethylene terephthalate (PET) sensors to create cost-effective, real-time monitoring solutions for cancer cells. Traditional biosensors often rely on pure gold electrodes, which can be prohibitively expensive for single-use applications. By employing gold coatings instead, this innovative approach not only reduces costs but also enhances the feasibility of deploying these sensors in various settings, including healthcare facilities and potentially even within smart construction materials.
“By utilizing gold coatings on more affordable substrates, we can provide a practical solution that maintains the sensitivity and reliability required for monitoring cancer cells,” said Mansor. This advancement opens doors for integrating biosensing technology into the built environment, allowing for real-time health monitoring systems embedded in construction materials. Imagine buildings that can detect health-related issues in occupants or monitor environmental factors that could affect well-being.
The study utilized interdigitated electrode designs, with Cu/Ni electrodes electroplated with gold on PCB and coated with gold using an electroless technique on PET. The researchers conducted thorough evaluations of the physicochemical properties of these sensors through advanced imaging techniques and electrochemical characterization. The results were promising, showing that both types of sensors were biocompatible and effective in monitoring the growth of SiHa cervical cancer cell lines.
Mansor noted the significance of these findings: “The ability to create biocompatible sensors that can be integrated into everyday materials means we could see a future where our buildings not only provide shelter but also contribute to health monitoring.” This could lead to a new era of smart cities and buildings that prioritize occupant health through embedded technology.
As the construction industry increasingly embraces smart technologies, the integration of biosensors could enhance safety and health monitoring, ultimately leading to better-designed environments that cater to the well-being of their inhabitants. This research not only highlights the potential for improved healthcare applications but also sets a precedent for future developments in the field of bioelectrochemistry and sensor technology.
For those interested in the intersection of engineering and health, this study represents a significant leap forward. The potential commercial impacts are vast, paving the way for innovative solutions that could redefine how we think about buildings and their role in our lives.
