Conjugated polyelectrolytes (CPEs) are polymers that feature a π-conjugated backbone functionalized with ionic groups. These polyelectrolytes exhibit a strong tendency to self-assemble in water, stimulated by multi-valent interactions with oppositely charged ions and hydrophobic interactions. The interaction between the solution state of the polymers and their optical properties makes it possible to design systems that allow sensitive and selective optical detection of a number of chemically- and biologically-relevant analytes. The talk will present several examples of CPE-based sensors, with an emphasis on recent investigations that target polyphosphates and which rely upon machine learning algorithms to discriminate between mammalian cell lines.
