Front Cover: Polypiperazines are hydrophilic pH-sensitive polymers reaching high transfection efficiency and guaranteeing good biocompatibility. They almost charge-neutral under physiological conditions avoiding unintended side effects, while the isopropyl-modified polypiperazine outperforms commercial linear PEI at low N/P ratios. qPCR revealed that pDNA can still be amplified complexed with p...

Luminescent silver cluster-based coordination polymers composed of Ag10 or Ag12 cluster cores and multidentate pyridine linkers were synthesized as well luminescent polymorphic silver(I)-based polymers. It was found that these exhibit highly sensitive luminescence quenching effect to nitrobenzene, attributed the π–π stacking interactions between nitrobenzene electron-withdrawing character nitro...

We developed and characterized a rapid, sensitive and integrated optical vapor sensor array for micro-gas chromatography (μGC) applications. The sensor is based on the Fabry-Pérot (FP) interferometer formed by a micrometre-thin vapor-sensitive polymer layer coated on a silicon wafer. The thickness and the refractive index of the polymer vary in response to the vapor analyte, resulting in a chan...
