Here, we show that extrinsic background can significantly affect a classification model using Raman images, yielding misleadingly high accuracies in the distinction of benign and malignant samples of ...

For precise characterizations of single-walled carbon nanotubes (SWCNTs) by optical absorption spectroscopy, the background extinction that originated from precipitable impurities and SWCNT bundles ...

This valuable paper shows image correlation spectroscopy (ICS) as a new tool to analyze the ... prior to fixation to reduce the background concentration and enhance the resolution of protein foci.
