TOKYO, Japan – A groundbreaking inspection system that can peek inside pharmaceutical pills in real-time, without damaging them, has been developed by researchers at Chuo University. This innovation promises to significantly enhance the safety and quality control of medications before they reach consumers.
Graphical abstract.
The system employs a novel combination of non-destructive terahertz (THz) and infrared (IR) photo-monitoring techniques, coupled with ultra-broadband sensitive imager sheets. This allows for detailed, real-time visualization of both the material composition and any potential foreign substances within pharmaceutical pills.
The research, published in Light: Science & Applications, addresses a critical gap in current pharmaceutical manufacturing. While in-line, non-destructive monitoring is vital for safe drug distribution, existing analytical systems frequently enough struggle to dynamically visualize the intricate details within pills. Traditional spectroscopy methods, while effective, often require bulky equipment that is impractical for real-time manufacturing lines.
This new approach overcomes those limitations by creating compact, dynamic photo-monitoring systems. The researchers developed a system using carbon nanotube (CNT) photo-thermoelectric imagers that work across an ultra-broadband spectrum, from sub-terahertz to infrared wavelengths.
“We can selectively extract informative wavelengths from thorough optical references of target pills,” the research team explained.
What makes CNTs especially favorable is their ability to efficiently absorb light and their compatibility with solution-processable configurations, enabling the creation of printable, thin-film imagers that can be easily attached to pharmaceutical monitoring sites.
The non-destructive dynamic monitoring system integrates these functional imager sheets with compact, multiple light sources. This setup allows for permeable sub-THz-IR irradiation. Different wavelengths of this irradiation exhibit varying transmittance values through non-metallic materials, effectively identifying constituent materials and even hidden foreign substances without physical contact.
This innovative technique allows for the inspection of even the most subtle, invisible features within pharmaceutical pills, ensuring a higher standard of quality control throughout the manufacturing process.
