Abstract
Stimuli-responsive synthetic polypeptide-containing block copolymers have received considerable attention in recent years. Especially, unique thermo-induced sol-gel phase transitions were observed for elaborately-designed amphiphilic diblock copolypeptides and a range of poly(ethylene glycol) (PEG)-polypeptide block copolymers. The thermo-induced gelation mechanisms involve the evolution of secondary conformation, enhanced intramolecular interactions, as well as reduced hydration and increased chain entanglement of PEG blocks. The physical parameters, including polymer concentrations, sol-gel transition temperatures and storage moduli, were investigated. The polypeptide hydrogels exhibited good biocompatibility in vitro and in vivo, and displayed biodegradation periods ranging from 1 to 5 weeks. The unique thermo-induced sol-gel phase transitions offer the feasibility of minimal-invasive injection of the precursor aqueous solutions into body, followed by in situ hydrogel formation driven by physiological temperature. These advantages make polypeptide hydrogels interesting candidates for diverse biomedical applications, especially as injectable scaffolds for 3D cell culture and tissue regeneration as well as depots for local drug delivery. This review focuses on recent advances in the design and preparation of injectable, thermo-induced physically crosslinked polypeptide hydrogels. The influence of composition, secondary structure and chirality of polypeptide segments on the physical properties and biodegradation of the hydrogels are emphasized. Moreover, the studies on biomedical applications of the hydrogels are intensively discussed. Finally, the major challenges in the further development of polypeptide hydrogels for practical applications are proposed.

Abstract
The present study reports a UV and dark-triggered highly intelligent drug delivery system for skin protection. ZnO nanoparticles (NPs), a UV filter, were synthesized and characterized to be the carrier for benzophenone-3 (Bp-3), a UV-absorption medicine, by varying the molar ratio of ZnO NPs to Bp-3 ranging from 300 : 1 to 20 : 1. The drug release under three cycles of UV and dark stimulation (each for two hours) and its cytotoxicity to human keratinocyte cells and skin fibroblasts were investigated. SEM studies showed the diameter of ZnO was around 30 to 40 nm, which assembled into loose and large NPs ranging from 500 to 1400 nm. Contact angle tests showed ZnO NPs switched to a more hydrophilic and back to a more hydrophobic state under two hours of UV and dark exposure. The optimized encapsulation efficiency and loading capacity of Bp-3 were 53.68 ± 0.13% and 133.61 ± 0.20% when the molar ratio of ZnO NPs to Bp-3 was 150 : 1 and 80 : 1. The Bp-3 was almost completely released from ZnO NPs under 2 hours of UV radiation and was mostly encapsulated in after 2 hours of dark stay in three cycles of UV and dark exposure. The Bp-3 loaded ZnO NPs showed low cytotoxicity to human keratinocyte cells and human skin fibroblasts. Overall, a UV and dark-triggered repetitively on-demand drug delivery system biocompatible to skin cells and potential for skin protection from UV radiation was developed.

Abstract
In order to impart pH-responsiveness within a physiologically-relevant context to PEG-based biomaterials, a new tertiary amine containing repeat unit, N,N-diisopropyl ethanolamine glycidyl ether (DEGE), was developed and incorporated into statistical and block copolymers with ethylene oxide (EO), and allyl glycidyl ether (AGE) via anionic ring-opening polymerization. The reactivity of this novel monomeric building block in copolymerizations with EO was investigated by spectroscopy with observed reactivity ratios of rDEGE = 1.28 ± 0.14 and rEO = 0.82 ± 0.10. It was further demonstrated that DEGE containing copolymers could serve as building blocks for the formation of new pH-responsive materials with a pKa of ca. 9, which allowed macroscopic hydrogels to be prepared from symmetric triblock copolymers PDEGE5.3k-b-PEO20k-b-PDEGE5.3k. The triblock copolymers exhibited clear sol-to-gel transitions in a physiologically-relevant critical gelation range of pH 5.8-6.6 and pH-dependent viscoelastic properties. On the nanometer scale, the preparation of pH-responsive micro- or nanogels was demonstrated by crosslinking P(DEGE-co-AGE) copolymers in miniemulsion droplets stabilized by PEO-b-P(DEGE-co-AGE) diblock terpolymers. These nanoparticles exhibited a reversible pH-dependent swelling profile with a volume phase transition at physiological pH 6.5-7.5.
