Abstract
Hyperbranched polymers hold great promise in nanomedicine for their controlled chemical structures, sizes, multiple terminal groups and enhanced stability than linear amphiphilic polymer assemblies. However, the rational design of hyperbranched polymer-based nanomedicine with low toxic materials, selective cellular uptake, controlled drug release, as well as real-time drug release tracking remains challenging. In this work, a hyperbranched multifunctional prodrug HBPSi-SS-HCPT is constructed basing on the nonconventional aggregation-induced emission (AIE) featured hyperbranched polysiloxanes (HBPSi). The HBPSi is a biocompatible AIE macromolecule devoid of conjugates, showing a high quantum yield of 17.88% and low cytotoxicity. By covalently grafting the anticancer drug, 10-hydroxycamptothecin (HCPT), to the HBPSi through 3,3'-dithiodipropionic acid, HBPSi-SS-HCPT is obtained. The HBPSis demonstrate obvious AIE features and it turned to aggregation-caused quenching (ACQ) after grafting HCPT owing to the FRET behavior between HBPSi and HCPT in HBPSi-SS-HCPT. In addition to on-demand HCPT release in response to changes in environmental pH and glutathione, a series of in vitro and in vivo studies revealed that HBPSi-SS-HCPT exhibits enhanced accumulation in tumor tissues through the enhanced permeation and retention (EPR) effect and preferential cancer cell uptake by charge reversal, thus resulting in apoptotic cell death subsequently. This newly developed multifunctional HBPSi-SS-HCPT prodrug provides a biocompatible strategy for controlled drug delivery, preferential cancer cell uptake, on-demand drug release and enhanced antitumor efficacy.

Abstract
Unlike normal conversion from aggregation caused quenching (ACQ) to aggregation induced emission enhancement (AIEE) by introducing aromatic rotors tuning aggregation modes, in this study, it is achieved through a supramolecular assembly with polymer. Thus, it provides an easy approach for the inhibition of unwanted H-aggregation between luminogens. As a kind of flavonoid, morin has shown great potential in therapeutics. However, its poor solubility and weak emission in aqueous solution greatly limit its bioapplications. When morin is dissolved in aqueous solution, the presence of 30 × 10-6 m polyethyleneimine (PEI) induces significant emission enhancement and bathochromic shift. Consequently, the quantum yield (QY) of 24.5% is either achieved by assembling with PEI, versus 0.76% of its ACQ state composed of H-aggregation in aqueous solution. Particularly, the in-depth mechanism studies reveal that it is the assembly with PEI that disassociates the H-aggregation in aqueous solution and further restricts the stretching and/or rotation of morin, which eventually reduce the nonradiative decays and enhance the emission. Therefore, the present study reports a unique phenomenon of AIEE effects on morin. Particularly the in-depth investigation on intrinsic mechanisms will highlight and greatly expand the development of more luminogens from traditional Chinese herbals.

Abstract
Specific detection of Plasmodium vivax lactate dehydrogenase (PvLDH), an important biomarker of malaria, remains a significant challenge. Herein, adenosine monophosphate protected gold-silver bimetallic nanoclusters, Au-AgNCs@AMP were used as a specific and sensitive fluorescence probe to detect PvLDH. After optimizing, a linear response was shown over a wide concentration range (10-100 nM) and an extremely low limit of detection (LOD) at 0.10 nM (3.7 ng mL-1) was achieved finally. Albeit the method was able to detect PvLDH sensitively, it could not discriminate different types of LDHs. Consequently, Al3+ was employed as an "assistant agent", which induced an assay capacity to discriminate PvLDH from other LDHs. The bimetallic nanoclusters inhibited the activity of PvLDH, suggesting it bound near the active site of PvLDH with high affinity. Zeta potential and UV-vis absorption experiments showed that electrostatic interaction was the main driving force for the interaction between the nanoclusters and PvLDH. Through chemical modification it indicated free thiol groups in PvLDH played an implant role in the interaction. Overall, the fluorescence enhancement and blue-shift were attributed to assembly-induced emission enhancement (AIEE) and hydrophobic transfer. The present study provides a simple, robust, and easy-to-perform approach to detect PvLDH with high sensitivity and selectivity, with significant potential for malaria diagnosis in the developing world.

Abstract
Functionalized hydrogels have aroused general interest due to their versatile applications in biomaterial fields. This work reports a hydrogel network composed of gold nanoclusters linked with bivalent cations such as Ca2+ , Mg2+ , and Zn2+ . The hydrogel exhibits both aggregation-induced emission (AIE) and aggregation-induced electrochemiluminescence (AIECL) effects. Most noteworthy, the AIECL effect (≈50-fold enhancement) is even more significant than the corresponding AIE effect (approximately fivefold enhancement). Calmodulin, a Ca2+ binding protein, may efficiently regulate the AIECL dynamics after specific binding of the Ca2+ linker, with the linear range from 0.3 to 50 µg mL-1 and a limit of detection of 0.1 µg mL-1 . Considering the important roles of bivalent cations in the life system, these results may pave a new avenue for the design of a biomolecule-responsive AIECL-type hydrogel with multifunctional biomedical purposes.
