Surface plasmon resonance (SPR) biosensors represent a pivotal advancement in real-time, label-free detection techniques, utilising the sensitive optical response at metal–dielectric interfaces to ...

SPR biosensors measure molecular interactions in real time. Several other methodologies determine affinity of complex formation, such as ELISA, analytical ultracentrifugation, equilibrium ...

In many ways, sensors make up the heart of Bioprocessing 4.0. So, an international team of scientists—with members from Australia, China, and the United States—developed what they described as an ...

Surface plasmon resonance (SPR) is a powerful technique for observing biomolecular interactions due to its ability to quantitatively measure real-time interactions without the need for labels or ...

Recently introduced Biacore S200 instrument, with the highest SPR detection sensitivity, enables high capacity analyses spanning a wide range of molecular sizes and affinities. S200 high sensitivity ...

(Nanowerk Spotlight) In modern medicine, the ability to detect disease markers early can mean the difference between life and death. Yet, detecting biomarkers like tumor necrosis factor-alpha (TNF-α) ...

Surface plasmons are collective oscillations of free electrons that occur at the interface between a metal and a dielectric medium, such as air or glass. These oscillations are coupled with ...

In a recent study posted to Sensors International, researchers conducted a brief review on biosensors based on sustainable materials for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ...

Optical fiber biosensors (OFBs) achieve ultra-low detection limits for biomarkers and toxins, yet face challenges in reproducibility and scalable manufacturing.
