Abstract
In this paper, we present a synergistic, experimental, and computational study of the self-assembly of N,N'-disubstituted polysulfamides driven by hydrogen bonds (H-bonds) between the H-bonding donor and acceptor groups present in repeating sulfamides as a function of the structural design of the polysulfamide backbone. We developed a coarse-grained (CG) polysulfamide model that captures the directionality of H-bonds between the sulfamide groups and used this model in molecular dynamics (MD) simulations to study the self-assembly of these polymers in implicit solvent. The CGMD approach was validated by reproducing experimentally observed trends in the extent of crystallinity for three polysulfamides synthesized with aliphatic and/or aromatic repeating units. After validation of our CGMD approach, we computationally predicted the effect of repeat unit bulkiness, length, and uniformity of segment lengths in the polymers on the extent of orientational and positional order among the self-assembled polysulfamide chains, providing key design principles for tuning the extent of crystallinity in polysulfamides in experiments. Those computational predictions were then experimentally tested through the synthesis and characterization of polysulfamide architectures.

Abstract
Nanocomposite tectons (NCTs) are nanocomposite building blocks consisting of nanoparticle cores functionalized with a polymer brush, where each polymer chain terminates in a supramolecular recognition group capable of driving particle assembly. Like other ligand-driven nanoparticle assembly schemes (for example those using DNA-hybridization or solvent evaporation), NCTs are able to make colloidal crystal structures with precise particle organization in three dimensions. However, despite the similarity of NCT assembly to other methods of engineering ordered particle arrays, the crystallographic symmetries of assembled NCTs are significantly different. In this study, we provide a detailed characterization of the dynamics of hybridizations through universal (independent of microscopic details) parameters. We perform rigorous free energy calculations and identify the persistence length of the ligand as the critical parameter accounting for the differences in the phase diagrams of NCTs and other assembly methods driven by hydrogen bond hybridizations. We also report new experiments to provide direct verification for the predictions. We conclude by discussing the role of non-equilibrium effects and illustrating how NCTs provide a unification of the two most successful strategies for nanoparticle assembly: solvent evaporation and DNA programmable assembly.

Abstract
An ideal drug delivery system must have a high level of stability to ensure effective circulation and passive aggregation, good retention performance, and dynamic delivery and treatment monitoring. Thus, the development of a smart drug delivery carrier with both precise drug release and real-time detection remains a challenge. Herein, we propose a confined crosslink protocol to prepare an intelligent hybrid delivery system for auto-fluorescent monitoring, protonation-induced retention and precise drug release. The construction of this system involves the hydrolysis and condensation of (3-aminopropyl)triethoxysilane (APTES) silanes inside the Pluronic polymer micelles and thereafter a confined Schiff base crosslinking between glutaraldehyde (GA) and residual silane amino groups. The size of the intelligent docetaxel (DTX)-loaded nanosystem changes from ∼25 nm in blood circulation or normal tissues (pH ∼ 7.4) to ∼250 nm in slightly acidic environments (pH ∼ 6.5-7.0) owing to intra-molecular hydrogen bond-induced aggregation and imine cleavage-induced disintegration in the endosome (pH ∼ 5.0-6.2) along with auto-fluorescent monitoring contributing to the high-efficiency chemotherapy. This work provides a new method to construct smart, acid-responsive and fluorescent-guided drug-delivery carrier systems for efficient and safe tumor chemotherapy.

Abstract
Using synchrotron-based small-angle X-ray scattering techniques, we demonstrate that poly(ethylene glycol)-functionalized gold nanoparticles (PEG-AuNPs) are assembled into close-packed structures that include short-range order with face-centered cubic structure, where crystalline qualities are varied by controlling the electrolyte concentration, pH, and temperature of the suspensions. We show that interpolymer complexation with poly(acrylic acid) (PAA) is induced by lowering the pH level of the PEG-AuNPs suspensions, and furthermore, increasing the temperature of the suspension strengthens interparticle attraction, leading to improved supercrystal structures. Our results indicate that this strategy creates robust nanoparticle superlattices with high thermal stability. The effects of PAA and PEG chain lengths on the assemblies are also investigated, and their optimal conditions for creating improved superlattices are discussed.
