Principal component analysis
TL;DR: Principal Component Analysis is a multivariate exploratory analysis method useful to separate systematic variation from noise and to define a space of reduced dimensions that preserve noise.

Principal component analysis: a review and recent developments
TL;DR: The basic ideas of PCA are introduced, discussing what it can and cannot do, and some variants of the technique have been developed that are tailored to various different data types and structures.

Chemical sensors based on amplifying fluorescent conjugated polymers.
TL;DR: This review restricts discussions to purely fluorescence-based methods using conjugated polymers (CPs) and details earlier research in this Introduction to illustrate fundamental concepts and terminology that underpin the recent literature.

Molecular Imprinting in Cross‐Linked Materials with the Aid of Molecular Templates— A Way towards Artificial Antibodies
TL;DR: In this article, the authors present a method analogous to a mechanism of antibody formation proposed earlier, by which in the presence of interacting monomers a cross-linked polymer is formed around a molecule that acts as a template.
