“…Of particular interest is controlling the assembly of inorganic or metallic NPs at the interface between different phase domains of BCPs, to achieve a high degree of order and even responsive behavior . These types of highly ordered hybrid materials have potential applications in flexible sensors, tunable plasmonic nanostructures for surface‐enhanced Raman scattering, ultrafast switches and organic memory devices, and advanced photovoltaic devices …”

Hybrid composites with highly ordered structures show promise for applications in various fields and thus there is great interest in their fabrication. In this context, Janus nanoparticles (JNPs) are synthesized with the aim of further incorporating them into polystyrene‐block‐poly(2‐vinylpyridine) (PS‐b‐P2VP) block copolymers to fabricate hybrid composites. It is observed that the dispersed JNPs are located at the boundary of the two morphological phases in PS‐b‐P2VP. The orientation of the lamellar structure in the bottom and free surface region of the block copolymer (BCP) composites shows a distinct difference as the composition of the JNPs is adjusted. The processing conditions of the nanoparticle/BCP composites are found to play an important role in achieving the desired structures.

“…These helical polymers are proven to be ideal building blocks for self-assembly of 2D and 3D smectic arrangements on a substrate, in solution and solid state. Several works concerning the different substituted helical PPI have been reported by us [ 154 , 155 , 156 , 157 ], and obtained a series of advanced morphology and performance. Therefore, we envision that introducing noncharged hydrophilic helical PPI chains that has a structural similarity to CPPs in the micelle shell may also facilitate intracellular delivery of cargos and create an artificial synthetic noncharged polymer-based delivery system.…”

Although a number of tactics towards the fabrication and biomedical exploration of stimuli-responsive polymeric assemblies being responsive and adaptive to various factors have appeared, the controlled preparation of assemblies with well-defined physicochemical properties and tailor-made functions are still challenges. These responsive polymeric assemblies, which are triggered by stimuli, always exhibited reversible or irreversible changes in chemical structures and physical properties. However, simple drug/polymer nanocomplexes cannot deliver or release drugs into the diseased sites and cells on-demand due to the inevitable biological barriers. Hence, utilizing therapeutic or imaging agents-loaded stimuli-responsive block copolymer assemblies that are responsive to tumor internal microenvironments (pH, redox, enzyme, and temperature, etc.) or external stimuli (light and electromagnetic field, etc.) have emerged to be an important solution to improve therapeutic efficacy and imaging sensitivity through rationally designing as well as self-assembling approaches. In this review, we summarize a portion of recent progress in tumor and intracellular microenvironment responsive block copolymer assemblies and their applications in anticancer drug delivery and triggered release and enhanced imaging sensitivity. The outlook on future developments is also discussed. We hope that this review can stimulate more revolutionary ideas and novel concepts and meet the significant interest to diverse readers.

Fabrication of SERS-active conjugated copolymers/gold nanoparticles composite films by interface-directed assembly

Abstract: A new composite film was synthesised by taking advantage of interface-directed assembly between thiol group-functionalized copolymers and Au NPs. The film not only exhibited strongly Au NP concentration-dependent SERS activity, but also allowed detection of a model molecule.
