AI Article Synopsis
- Researchers developed a method to create ultra-small (sub-2-nm) uniform oxide nanocrystals and structured superstructures in a single step using oleylamine and oleic acid.
- The unique growth and assembly process led to the formation of ribbon-like superstructures from these tiny nanocrystals.
- This technique is versatile and can be applied to produce various other transition and rare earth metal oxide nanocrystals.
Article Abstract
Sub-2-nm (down to one-unit cell) uniform oxide nanocrystals and highly ordered superstructures were obtained in one step using oleylamine and oleic acid as capping and structure directing agents. The cooperative nature of the nanocrystal growth and assembly resulted in mesoscopic one-dimensional ribbon-like superstructures made of these ultrathin nanocrystals. The process reported here is general and can be readily extended to the production of many other transition metal (TiO2, ZnO, Nb2O5) and rare earth oxide (Eu2O3, Sm2O3, Er2O3, Y2O3, Tb2O3, and Yb2O3) systems.

Cancer immunotherapies rely on CD8 cytolytic T lymphocytes (CTLs) in recognition and eradication of tumor cells via antigens presented on major histocompatibility complex class I (MHC-I) molecules. However, we observe MHC-I deficiency in human and murine urologic tumors, posing daunting challenges for successful immunotherapy. We herein report an unprecedented nanosonosensitizer of one-dimensional bamboo-like multisegmented manganese dioxide@manganese-bismuth vanadate (BMMBV) to boost multiple branches of immune responses targeting MHC-I-deficient tumors.

In this study, a novel inhibitor of ERCC1/XPF heterodimerization, A4, was used as an inhibitor of repair for DNA damage by platinum-based chemotherapeutics. Nano-formulations of A4 were developed, using self-assembly of the following block copolymers: methoxy-poly(ethylene oxide)-block-poly(α-benzyl carboxylate-ε-caprolactone) (PEO-b-PBCL), methoxy-poly(ethylene oxide)-block-poly(ε-caprolactone) (PEO-b-PCL), or methoxy-poly(ethylene oxide)-block-poly (D, L, lactide) (PEO-b-PDLA 50-50). The nano-formulations were characterized for their average diameter, polydispersity, morphology, A4 encapsulation and in vitro release.

The global prevalence of Parkinson's Disease (PD) is on the rise, driven by an ageing population and ongoing environmental conditions. To gain a better understanding of PD pathogenesis, it is essential to consider its relationship with the ageing process, as ageing stands out as the most significant risk factor for this neurodegenerative condition. PD risk factors encompass genetic predisposition, exposure to environmental toxins, and lifestyle influences, collectively increasing the chance of PD development.
