Nanoarchitectonics offers a systematic approach to creating an artificial framework by integrating different multiscale components such as semiconductor lattices and biological substances. However, most nanoarchitectonic abiotic–biotic hybrid systems have intrinsic limitations in imparting nonequilibrium biological features into semiconductor lattices at the nanoscale. Here, we report a new nanoarchitectonic system integrating bismuth oxychloride (BiOCl) nanosheets with purple membrane (PM) patches. PM is an archaeal subcellular fraction capable of unidirectionally transferring photogenerated charge carriers to its surroundings at the nanoscale independent of archaeal metabolism and retaining this dynamic functionality after isolation from living archaea. Microscopy, spectroscopy, electrochemical, and synchrotron X-ray scattering analyses verify that the nanoarchitectonic hybridization between BiOCl and PM generates a vertical heterostructure, thereby enhancing photogenerated charge-carrier dynamics and enabling the associated photocatalytic capacity. The resulting PM–BiOCl hybrid nanosheets efficiently convert dioxygen into hydrogen peroxide through a two-electron and two-proton transfer process under ambient conditions while simultaneously converting ethylene glycol into value-added chemicals. This study presents a nanoarchitectonic approach that leverages the photogenerated charge-carrier dynamics of the archaeal subcellular fractions to modulate the optoelectronic and catalytic capacity limitations of semiconductors.

Argonne' CNM Research Highlight - "Turning Nitrogen into Ammonia with a Hybrid Nano-Bio Catalyst": Link
Introduced in Hanbitsa (People Glorifying Korea): Link
Photosynthetic biohybrid systems (PBSs) offer an eco-friendly approach to transforming solar energy into value-added products by integrating biological entities with inorganic semiconductors. However, the chemical conversion capacity of most PBSs has inherent limitations, as whole-cell bacteria and isolated enzymes require fine-tuning of environmental conditions. Here, we report a new PBS developed by introducing free-standing ceria nanoparticles into the purple membrane (PM) of Halobacterium salinarum archaea, which can unidirectionally transfer charge carriers in response to incident photons, even after separation from living archaea at various conditions. Our microscopy, spectroscopy, and synchrotron X-ray scattering analyses confirm that the electrostatic assembly between ceria and PM creates seamless interfacial contact, thereby enhancing the photocatalytic capacity of ceria. Although the conversion of dinitrogen (N2) to ammonia (NH3) is thermodynamically challenging due to the triple bond in N2 and a series of charge-transfer reactions, our PM–ceria (PMC) hybrid nanoparticle efficiently produces NH3 by reducing N2 using solar energy even under atmospheric pressure and room temperature while simultaneously converting glycerol into value-added derivatives. Additionally, our PMC nanoparticle involves neither toxic/precious metals nor bioengineering processes to achieve enhanced photocatalytic N2-to-NH3 conversion. This study sheds light on the new aspect of PBSs by employing PM to potentially resolve the global energy and environmental challenges posed by the conventional Haber–Bosch process.

Nanodiamonds (NDs), tetrahedral carbon structures with a size ranging from 1 to 100 nm, have gained growing attention in recent years due to their distinct optical, thermal, and mechanical propertiescompared to other carbon nanomaterials (e.g., graphene, carbon nanotubes, carbon dots). Combined with a high surface-to-volume ratio and tunable and chemically versatile surfaces, these support broad applications across catalysis, electronics, and life sciences. Moreover, the biocompatible characteristics of NDs enable their controllable interfacial interactions with biological systems, positioning them as excellent candidates for advancing cutting-edge biomedical sciences, particularly through the engineering of efficient material biointerfaces that facilitate optimal interactions with biological systems. Among various forms of NDs, fluorescent nanodiamonds (FNDs) have emerged as some of the most impactful and rapidly advancing materials, demonstrating strong potential in ultrasensitive spin-enhanced bioimaging, high-precision biosensing, traceable drug delivery, and quantum-enabled biomedical technologies. This Review introduces the key principles underlying NDs and FNDs, including their structural properties, synthesis methods, and surface functionalization strategies. It also highlights emerging biomedical applications of NDs and FNDs, with particular emphasis on neurological disorders. Finally, the article discusses current challenges in advancing NDs as a multifunctional platform for neural therapies with translational potential toward clinical trials.

Lateral Piezoelectricity of Alzheimer’s Aβ Aggregates
Advanced Science 2024, 11 (39), 2406678. [I.F. = 14.1, JCR = 92.9%, 2024]

Alzheimer’s disease (AD) is the most frequent neurodegenerative disorder in the elderly aged over 65. The extracellular accumulation of beta-amyloid (Aβ) aggregates in the brain is considered as the major event worsening the AD symptoms, but its underlying reason has remained unclear. Here we reveal the piezoelectric characteristics of Aβ aggregates. Our vector piezoresponse force microscopy (PFM) analysis results exhibit that Aβ fibrils have spiraling piezoelectric domains along the length and a lateral piezoelectric constant of 44.1 pC N-1. Also, our continuous sideband Kelvin probe force microscopy (KPFM) images display that the increment of charge-induced surface potential on a single Aβ fibril is allowed to reach above +1,700 mV in response to applied forces. Our findings shed light on the peculiar mechano-electrical surface properties of pathological Aβ fibrils that exceed those of normal body components.

A Hierarchical Shell Locks and Stabilizes Perovskite Nanocrystals with Near-Unity Quantum Yield
Science 2026, 391 (6782), eady1370. [I.F. = 47.3, JCR = 98.2%, 2025]
Solid-state emitters have exhibited external quantum yields (EQYs) below 65%, with no system combining unity photoluminescence quantum yield (PLQY) and commercially viable stability. These limitations are most pronounced in colloidal perovskite nanocrystals (PeNCs), given their soft ionic lattices and labile surfaces. We introduce a hierarchical shell (HS) structure comprising interbonded PbSO4-SiO2-polymer multilayers that simultaneously locks and stabilizes soft lattices and labile interfaces. HS-CsPbBr3 PeNC films exhibit T90 (10% PLQY loss) = 3211 hours under accelerated 60°C, 90% relative humidity (RH) and T90 = 12,000 hours under blue-light exposure. HS strategy generalizes across PeNC compositions—including mixed-halide, mixed-cation, iodide, and hybrid PeNCs—and enables MAPbBr3 with extended T90 = 3900 hours (60°C, 90% RH) and T90 = 27,234 hours (blue light). Moreover, HS-MAPbBr3 films with 100.0% PLQY eliminate self-absorption losses and achieve an EQY of 91.4%, approaching the theoretical maximum. The HS barrier also prevents lead leakage for safety of large-area, high-resolution displays and bio-optoelectronics.
