Abstract
A new class of ferrocenyl surfactants based on covalent linkage between amino acids or peptides and ferrocene was designed. Accordingly, five ferrocenyl amphiphiles, FcS1-5, were synthesized, and their aggregation behaviors in aqueous solutions were studied. Compared to the other surfactants containing ferrocenyl units, FcS have a relatively smaller size and low molecular weight and are easy to synthesize. The influences of the number of carboxylic acid head groups and the number of Fc group in the hydrophobic tail, on the stability and aggregation behavior of these amphiphiles in aqueous medium, were explored to deduce the structure property relationships. A combination of fluorescence and dynamic light scattering techniques was used to elucidate the behavior of these molecules. A good agreement between the results obtained using different techniques was observed.

Abstract
The fabrication of novel and intelligent delivery systems that can effectively deliver therapeutics to the targeted site and release payload in enhanced/controlled manner is highly desired to overcome the multiple challenges in chemotherapy. The present article demonstrates the potential application of dual stimuli responsive nanogels as tumor microenvironment targeted drug delivery carrier. Disulfide cross-linked pH and redox responsive PEG-PDMAEMA nanogels were synthesized by atom transfer radical polymerization (ATRP). The nanogels were characterized by nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The PEG-PDMAEMA nanogels exhibited dual stimuli-responsive release of the encapsulated model anticancer drug (doxorubicin, DOX) due to the acidic pH-response of dimethyl amine group in PDMAEMA and reductive cleavage of the disulfide linkages. A relatively higher release of DOX was observed from the nanogels at pH 5.0 than at pH 7.4. DOX release was further accelerated in tumor simulated environment of pH 5.0 and 10 mM glutathione (GSH). Confocal microscopy images revealed that DOX-loaded PEG-PDMAEMA nanogels can rapidly internalize and effectively deliver the drug into the cells. The nanogels exhibited higher cytotoxicity in GSH-OEt pretreated HeLa cells than untreated cells. The dual stimuli responsive nanogels synthesized in this study exhibited many favorable traits, such as pH and redox dependent controlled release of drug, biodegradability, biocompatibility, and enhanced cytotoxicity, which endow them as a promising candidate for anticancer drug delivery.

Abstract
Surfactants are functional molecules comprising a water-compatible head group and a hydrophobic tail. One of their features is the formation of self-assembled structures in contact with water, for instance, micelles, vesicles, or lyotropic liquid crystals. One way to increase the functionality of surfactants is to implement moieties containing transition-metal species. Ferrocene-based surfactants represent an excellent example because of the distinguished redox features. In most existing ferrocene-based amphiphiles, an alkyl chain is classically used as the hydrophobic tail. We report the synthesis and properties of 1-triisopropylsilylethynyl-1'-trimethylammoniummethylferrocene (FcNMe3TIPS). In FcNMe3TIPS, ferrocene is part of the head group (Gemini design) but is also attached to a (protected) π-conjugated ethynyl group. Although this architecture differs from that of classical amphiphiles and those of other ferrocene-based amphiphiles, the compound shows marked surfactant properties comparable to those of lipids, exhibiting a very low value of critical aggregation concentration in water (cac = 0.03 mM). It forms classical micelles only in a very narrow concentration range, which then convert into monolayer vesicles. Unlike classical surfactants, aggregates already form at a very low concentration, far beneath that required for the formation of a monolayer at the air-water interface. At even higher concentration, FcNMe3TIPS forms lyotropic liquid crystals, not only in contact with water, but also in a variety of organic solvents. As an additional intriguing feature, FcNMe3TIPS is amenable to a range of further modification reactions. The TIPS group is easily cleaved, and the resulting ethynyl function can be used to construct heterobimetallic platinum-ferrocene conjugates with trans-Pt(PEt3)2X (X = Cl, I) complex entities, leading to a heterobimetallic surfactant. We also found that the benzylic α-position of FcNMe3TIPS is rather reactive and that the attached ammonium group can be exchanged by other substituents (e.g., -CN), which offers additional opportunities for further functionalization. Although FcNMe3TIPS is reversibly oxidized in voltammetric and UV-vis spectroelectrochemical experiments, the high reactivity at the α-position is also responsible for the instability of the corresponding ferrocenium ion, leading to a polymerization reaction.

Abstract
Hydrogen peroxide (H2 O2 )-responsive materials have been employed as drug delivery or diagnostic systems to treat or detect diseases with abnormal oxidative stress. A number of H2 O2 -responsive systems have been developed, and they have achieved great progress in controlled drug delivery for disease treatment. However, pathological sites with elevated H2 O2 level, such as cancer and inflammation, have their own characteristics; therefore the material structures and the subsequent formulations should be reasonably designed to acquire maximized therapeutic effects. In this progress report, we overview the development of H2 O2 -responsive functional groups for constructing H2 O2 -responsive formulations, as well as the guidance for designing suitable formulations to treat each specific pathological condition. The challenges and perspectives in this field are also discussed.

Abstract
SIGNIFICANCE Reactive oxygen species and reactive nitrogen species (ROS/RNS) play an important role in cell signaling pathways. However, the increased production of these species may disrupt cellular homeostasis, giving rise to pathological conditions. Biomaterials that are responsive to ROS/RNS can be strategically used to specifically release therapeutics and diagnostic agents to regions undergoing oxidative stress. RECENT ADVANCES Many nanocarriers intended to exploit redox micro-environments as triggers for drug release, summarized and compared in this review, have recently been developed. We describe these carriers' chemical structures, strategies for payload protection and oxidation-selective release, and ROS/RNS sensitivity as tested in initial studies. CRITICAL ISSUES ROS/RNS are unstable, so reliable measures of their concentrations in various conditions are scarce. Combined with the dearth of materials shown to respond to physiologically relevant levels of ROS/RNS, evaluations of their true sensitivity are difficult. FUTURE DIRECTIONS Oxidation-responsive nanocarriers developed thus far show tremendous potential for applicability in vivo; however, the sensitivity of these chemistries needs to be fine tuned to enable responses to physiological levels of ROS and RNS.

Abstract
Redox responsive nanotubes were fabricated by the template assisted layer-by-layer (LbL) assembly method and employed as platforms for molecular payload release. Positively and negatively charged organometallic poly(ferrocenylsilane)s (PFS) were used to construct the nanotubes, in combination with other polyions. During fabrication, multilayers of these polyions were deposited onto the inner pores of template porous membranes, followed by subsequent removal of the template. Anodized porous alumina and track-etched polycarbonate membranes were used as templates. The morphology, electrochemistry, composition and other properties of the obtained tubular structure were characterized by fluorescence microscopy, scanning (SEM) and transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX) spectroscopy. Composite nanotubes, consisting of poly(acrylic acid) anions with PFS(+) and nanoparticles including fluorophore labelled dextran and decorated quantum dots, with PFS polyelectrolytes were also fabricated, broadening the scope of the structures. Cyclic voltammograms of PFS containing nanotubes showed similar redox responsive behaviour to thin LbL assembled films. Redox triggered release of labelled macromolecules from these tubular structures demonstrated application potential in controlled molecular delivery.

Abstract
Intracellular pH-sensitive micelles of PEG-block-acetalated-dextran (PEG-b-AC-Dex) were prepared and used for acid-triggered intracellular release of anticancer drug. The hydrodynamic radii (Rh) of PEG-b-AC-Dex micelles could increase after incubation in PBS solution at pH 5.5. Based on the pH-responsive Rh variation behavior, it was expected that the PEG-b-AC-Dex micelles should be interesting for intracellular drug delivery. Thus, doxorubicin (DOX), a wide-spectrum anticancer drug, was loaded into the micelles and the pH-dependent release of the payload DOX was tested in vitro. The in vitro drug release profiles showed that only a small amount of the loaded DOX was released in PBS solution at pH 7.4, while up to about 90% of the loaded DOX could be quickly released in PBS solution at pH 5.5. Compared to pH-insensitive PEG-PLA micelles, the PEG-b-AC-Dex micelles displayed a faster drug release behavior in tumor cells. Moreover, higher cellular proliferation inhibition efficacy was achieved toward tumor cells. These features suggested that DOX could be efficiently loaded and delivered into tumor cells in vitro by the intracelluar pH-sensitive micelles, leading to enhanced inhibition of tumor cell proliferation. Therefore, the pH-sensitive micelles may provide a promising carrier for acid-triggered drug release for cancer therapy.
