Early diagnosis of pancreatic ductal adenocarcinoma by signal-enhanced lateral flow immunoassay: SELFI

Currently reported early-diagnostic method for Pancreatic Ductal Adenocarcinoma (PDAC) tends to be invasive and usually time-consuming. Here, this group reports an early diagnostic method of PDAC using a signal-enhanced lateral flow immunoassay which can generate a strong colorimetric signal through multiple hotspots formed by plasmonic gold nanoparticles assembled on silica nanoparticles.
