Polycyclic aromatic hydrocarbons (PAHs) are persistent contaminants in the environment. Several of them have carcinogenic properties. There is considerable interest in their sensitive low-cost detection and monitoring. We present a simple paper-based

Flavonoids are the most abundant polyphenols in the human diet and are ascribed a potentially beneficial effect against cancers, diabetes, and oxidative stress. The broad range of bioactivities and number of different flavonoids in a multitude of com

We report a polymer-based sensor that rapidly detects cancer based on changes in serum protein levels. Using three ratiometric fluorescence outputs, this simple system identifies early stage and metastatic lung cancer with a high level of accuracy ex

A cross‐reactive optical sensor array based on poly(p‐phenyleneethynylene)s (PPEs) determines Edman degraded amino acids. We report a sensor array composed of three anionic PPEs P1–P3, and their electrostatic complexes with metal ions (Fe2+, Cu

A hypothesis-free sensor array (optoelectronic tongue) composed of an anionic, a cationic and two neutral poly(para-aryleneethynylene)s (PAE) at pH 3, 7 and 13 discriminate more than 30 spirits (including brandy, Branntwein, Cognac, Spirituose, and W

Fluorescent, water-soluble poly(p-aryleneethynylene)s (PAE) were immobilized on commercially available nylon membranes by using a slot plotter, creating fluorescent, barcode-like sensor strips. Digital imaging by using a standard digital camera, befo

Four tetraphenylethene (TPE)-based aryleneethynylene-type polymers (TPEPs) are reported in this work. All of them show aggregate-induced emission (AIE). Their optical properties have been investigated. The TPEPs are tested as a sensor array for 14 di

The synthesis and quenching behavior of a series of water-soluble, carboxylate-carrying phenyleneethynylene oligomers-monomer to tetramer-and their polymers are reported; their quenching behavior with different test analytes (paraquat, lead salts, me

Summary In biology, non-specific interactions are ubiquitous and important, whereas in chemistry, non-specificity or non-selectivity is suspect. We present simple tongues consisting of fluorescent polyelectrolytes or chimeric green fluorescent protei

We have prepared four water-soluble poly(p-phenyleneethynylene)s, two of which are novel and carry benzylic side chains that are negatively charged. All of the four PPEs were employed to detect nitroaromatic compounds in water. The two novel PPEs wit
