Article Abstract

Developing simple and general approaches for the synthesis of nanometer-sized DNA materials with specific morphologies and functionalities is important for various applications. Herein, a novel approach for the synthesis of a new set of DNA-based nanoarchitectures through coordination-driven self-assembly of Fe ions and DNA molecules is reported. By fine-tuning the assembly, Fe-DNA nanospheres of precise sizes and controlled compositions can be produced. The hybrid nanoparticles can be tailored for delivery of functional DNA to cells in vitro and in vivo with enhanced biological function. This highlights the potential of metal ion coordination as a tool for directing the assembly of DNA architectures, which conceptualizes a new pathway to expand the repertoire of DNA-based nanomaterials. This methodology will advance both the fields of DNA nanobiotechnology and metal-ligand coordination chemistry.

Myocardial injury constitutes a life-threatening complication of sepsis, driven by synergistic oxidative-inflammatory pathology involving dysregulated production of reactive oxygen species (ROS), reactive nitrogen species (RNS), and proinflammatory cytokines. This pathophysiological cascade remarkably elevates morbidity and mortality rates in septic patients, emerging as a key contributor to poor clinical outcomes. Despite its clinical significance, no clinically validated therapeutics currently exist for managing septic cardiomyopathy.

Multi-layered and orthogonal recognition is an excellent route to controlled molecular complexity. Here we report a series of heteroleptic complexes where two ligands pair together at a palladium(II) metal centre in complementary fashion and with orthogonality to others pairs. This complementarity is driven in part through hydrogen-bonding acceptor or donor sites proximal to the coordination domain (either DD:AA or AD:DA).

Stereoselective Self-Assembly of a Topologically Chiral [6]Catenane with 18 Crossings.

Mechanically interlocked molecules (MIMs) exhibit unique properties and functions arising from their structural entanglement, features of which are absent in their individual components. However, synthesizing topologically complex architectures, particularly those with topological chirality, remains a significant challenge due to the lack of general methods for controlled entanglement. Herein, we report the stereoselective synthesis of a 24-metal-center topologically chiral [6]catenane featuring 18 crossings ( link), representing one of the most intricate MIMs constructed to date.

Ischemic stroke (IS) is a serious cerebrovascular disease. Due to its complex pathophysiological mechanisms and the limitation of drug delivery by the blood-brain barrier (BBB), current treatments for IS still struggle to achieve ideal outcomes. In this study, a multifunctional bimetallic phenolic network nanoparticle (Sr/Mn@Rh) formed via simple metal-phenolic coordination-driven self-assembly of Mn²⁺, Sr²⁺, and rutin hydrate (Rh) was developed for IS therapy.

The growing demand for sustainable biomanufacturing has driven significant interest in 2,5-furandicarboxylic acid (FDCA), a bio-based platform chemical for producing renewable polymers. The eco-friendly oxidoreductase laccase exhibits promising FDCA biosynthesis capacity yet is hampered by pH-dependent activity decay and susceptibility to proteolytic degradation. Herein, we developed a bio-enabled synthesis approach to fabricate three-dimensional laccase-integrated copper hybrid nanoflowers (Lac-NFs) through enzyme-metal coordination-driven self-assembly.
