A group of researchers from Universiti Putra Malaysia (UPM) successfully invented a Surface Plasmon Resonance (SPR) Sensor Chip, an an innovation that swiftly detects dengue virus at early stages.
As an optical device, SPR is highly sensitive to any changes in refractive fluid index, including blood and water, adjacent to a layer of metal surface required to produce this phenomenon.
Based on this concept, SPR has high potential of emerging as an effective alternative optical sensor. Read More
