Lacking rapid and reliable pathogen diagnostic platforms, inadequate or delayed antimicrobial therapy could be made, which greatly threatens human life and accelerates the emergence of antibiotic-resistant pathogens. In this contribution, a series of simple and reliable sensor arrays based on tetraphenylethylene (TPE) derivatives are successfully developed for detection and discrimination of pathogens. Each sensor array consists of three TPE-based aggregation-induced emission luminogens (AIEgens) that bear cationic ammonium group and different hydrophobic substitutions, providing tunable logP (n-octanol/water partition coefficient) values to enable the different multivalent interactions with pathogens. On the basis of the distinctive fluorescence response produced by the diverse interaction of AIEgens with pathogens, these sensor arrays can identify different kinds of pathogens, even normal and drug-resistant bacteria, with nearly 100% accuracy. Furthermore, blends of pathogens can also be identified accurately. The sensor arrays exhibit rapid response (about 0.5 h), high-throughput, and easy-to-operate without washing steps.

Aggregation induced emission (AIE) active copolymers P1-P6 with high molecular weights (14 000-17 000) and low polydispersity indices (1.3-1.4) were prepared through copolymerization of N-isopropyl acrylamide (NIPAM) and tetra(phenyl)ethene (TPE)-based acrylate monomers. Copolymers P1-P6 show comparable thermal stability to poly(N-isopropylacrylamide) (PNIPAM), while their glass transition temperatures are higher by 7-9 °C than those of pristine PNIPAM. Copolymers P1-P6 are soluble in common organic solvents as well as in water. They retain a similar thermal sensitivity to PNIPAM, but their lower critical solution temperatures (LCST) are reduced with increase of TPE content. By changing the molar ratio of P1-P6/poly(methacrylic acid) (PMAA) and pH, complexes P1-P6-PMMA were studied by fluorescence spectroscopy and dynamic light scattering (DLS). The complexes are non-emissive in THF, and their fluorescence can be turned on upon addition of water. Moreover, their fluorescence is enhanced with the decrease in pH values due to the formation of interpenetrating polymer networks (IPNs) through inter-polymer hydrogen bonding. Fluorescence spectroscopy and DLS results also reveal that the phase transition behaviour of IPNs upon heating could be significantly modified by pH change. Reduction in the pH value from 7.0 to 4.0 leads to the decrease in LSCT of IPNs by up to 5 °C with respect to PNIPAM. By tuning the pH value to dissociate the formed inter-polymer hydrogen bonds, the formed IPNs would be able to fold cooperatively to a compact structure without a loss of solubility at temperatures below the LCST. Thus, these novel IPNs with AIE active moieties would be used as drug delivery systems, in which the release process could be readily monitored by fluorescence spectroscopy.

In this work the fabrication of fluorescent microstructures through the e-beam induced solidification of two types of room temperature ionic liquids (RTILs) with fluorescent organic dyes is reported. It is shown that, by introducing dual-step e-beam patterning method with controlled accelerating voltage, solid micro-sized reservoirs are fabricated with liquid phase RTIL sealed inside. The presence of liquid inside the containers is confirmed by measuring their fluorescence spectra and comparison with results obtained for solid RTIL. The impact of the electron dose (ED) used in the exposure process on robustness and fluorescence characteristics of the fabricated structures is investigated. The temperature response of the micro reservoirs is also examined. The advantage of liquid – filled micro reservoirs is that they remain highly fluorescent, while solid RTIL structures exhibit significant fall in fluorescence ability associated with e-beam exposure damage.
