Development of protein corona sensor array for diagnostic purposes, (a) Scheme showing the formation of protein corona on the surface of multi-nanoparticles after interactions with patient plasmas to define “fingerprint” patterns specific to the diseases type, using advanced classifiers, (b-d) Use of two distinct supervised classifiers consisting of (b) partial least-squares discriminant analysis (PLS-DA) and (c,d) counter-propagation artificial neural network algorithm (CPANN) to analyze protein corona profiles for identification and separation of 5 distinct cancer types from each other and from healthy controls.
