Abstract
A gelator 1 containing functional quinoline and Schiff base groups that could form organogels in DMF, DMSO, acetone, ethanol and 1,4-dioxane was designed and synthesized. The self-assembly process of geator 1 was characterized by field emission scanning electron microscopy (FESEM), UV-vis absorption spectroscopy, fluorescence emission spectroscopy, Fourier transform infrared spectroscopy(FTIR), X-ray powder diffraction (XRD) and water contact angle. Under non-covalent interactions, gelator 1 self-assembled into microbelts and nanofiber structures with different surface wettability. Weak fluorescence was emitted from the solution and gel state of 1. Interestingly, gelator 1 exhibited good selectivity and sensitivity towards Zn2+ in solution and gel states along with its emission enhancement and change. The emission intensity at 423 nm of solution 1 in 1,4-dioxane was slightly enhanced, and a new emission peak appeared at 545 nm along with its intensity sequentially strengthened in the titration process. The obvious ratiometric detection process was presented with a limit of detection (LOD) of 5.51 μM. The detection mechanism was revealed by a theoretical calculation and NMR titration experiment, which was that Zn2+ induced the transition from trans- to cis- of molecule 1 and further coordinated with 1. This study will introduce a new method for the construction of functional self-assembly gel sensors for the detection of Zn2+.

Abstract
A water-soluble macrocyclic host is reported, composed of alkoxyanthracene as the donor (D), and 4,4-bipyridinium as the acceptor (A). The intramolecular D-A structure renders the host highly photostable. However, the introduction of a strong electron-donating guest promotes the photodecomposition of alkoxyanthracene, yielding photolyzable host-guest complexes or aggregates.

Abstract
Amphiphilic peptides modified by molecular design can self-assemble into specific nanostructures with interesting applications in the fields of biomedicine and biotechnology. Lysyl oxidase (LO) is ubiquitous in human serum. However, enzymatic self-assembly of amphiphilic peptides remains a challenge for lipid-soluble drug delivery under the induction of LO. Here, we designed a positively charged amphiphilic peptide, A6K2, that could stably self-assemble to form nanovesicles. The lysine in the peptide molecule could be covalently cross-linked under enzyme catalysis, and the major transition was from random coil to β-sheet secondary structures, eventually leading to the destruction of the peptide nanovesicles. The lipid-soluble antitumour drug doxorubicin (DOX) as a model drug could be loaded into the hydrophobic core of the nanovesicles formed by the amphiphilic peptide A6K2, even though DOX was not covalently linked to the peptide monomer. The amount of DOX-encapsulated A6K2 nanovesicles in human hepatocellular carcinoma BEL-7402 cells was significantly higher than that in human liver L02 cells, indicating excellent selectivity. The amphiphilic peptide A6K2 inhibited tumour cell growth and had low cytotoxicity to mammalian cells, and it showed antibacterial activity against G+ and G- bacteria. These advantages make enzymatic self-assembling A6K2 nanovesicles of great interest in drug delivery for biomedical applications.

Abstract
Tissue-specific self-assemblies of supramolecular hydrogels have attracted great interest in material design and biomedical applications, for in situ-formed hydrogels serve as an excellent local depot with tunable release of drug therapeutics. Here we report the design and syntheses of a novel class of histidine-containing hexapeptide derivatives (Nap-1 and ID-1) for in situ hydrogelation at the zinc ion-rich prostate tissue. Thanks to the efficient co-ordination between zinc and histidine, both Nap-1 and ID-1 displayed excellent self-assembly capability with a high sensitivity to zinc ions at ∼0.1 equivalency. To foster a prostate-specific drug delivery system (DDS), ID-1 was chosen for further conjugation with bicalutamide (BLT), a clinically used drug for prostate cancer. The as-synthesized ID-1-BLT retained the self-assembly capability with zinc ions, and conferred supramoelcular hydrogels at the prostate site. Interestingly, ID-1-BLT hydrogels demonstrated tunable drug release profiles in a typical tumor microenvironment, with acidic pH and esterase activity regulating the drug release in a dose dependent manner. Consequently, the hydrogel-based DDS demonstrated enhanced potency and selective cytotoxicity against prostate cancer cell DU145 over normal fibroblast cell NIH3T3, plausibly due to differential cellular uptake of drugs as well as the elevated esterase activities in cancer cells. Finally, the biocompatible hydrogel system demonstrated sustained delivery of drugs at the prostate gland of rats, with a superior in situ drug distribution profile compared to that of aqueous solution of BLT alone.
