Radiative-surface plasmon resonance for the detection of apolipoprotein E in medical diagnostics applications

The regulation of human apolipoprotein E, a gastric cancer biomarker, is evaluated using a novel radiative surface plasmon resonance platform, and employing an improved functionalization strategy to properly orient antibody. The up-regulation of apolipoprotein E, present in gastric cancer patients, is detectable in less than 1 h.225
