Nano-CaCO₃ is a potential nanomaterial at present. In this paper, the preparation process (physical and chemical methods), modification methods (physical and chemical modification), and application fields (chemical, energy, food, biomedicine, and environment industries) of nano-CaCO₃ are introduced and discussed. This provides theoretical guidance for people who understand the field.

Development of a platform for synthesis, surface modification with cRGD peptide, characterization and functional testing of ultrasmall gold nanoparticles for applications in nanomedicine.

Bio-fabricates ZnO-NPs from A. capillus-veneris L. plant, evaluating their antimicrobial, anti-inflammatory, and antioxidant effects. UV–vis absorption at 360 nm confirms production success. X-ray diffraction verifies hexagonal crystallinity, while Scanning Electron Microscope images show spherical nanoparticles. Energy Dispersive X-Ray analysis confirms high purity with only zinc and oxygen. ZnO-NPs effectively inhibit both Gram-positive and Gram-negative bacteria due to plant leaf bioactive compounds.

Silver nanowires are used in transparent conductive electrodes but suffer from atmospheric corrosion. Existing stabilization techniques for silver nanowire layers require embedding or submersion in liquid. Here, solvent vapor annealing and plasma treatment are identified as alternative stabilization approaches. Solvent vapor annealing has additional potential to create polymer matrix/nanowire composites from all-colloidal precursors, avoiding film transfer, or viscous polymer solutions.

This study reports fluorescent MOF-polymer composites based on Zr-MOFs (UiO-66 and UiO-66(OH)₂) and the conjugated polyelectrolyte PPE-CO₂-108. The defect-rich Zr-MOFs enable strong interactions between the polyelectrolyte's carboxylate groups and the MOF's Zr clusters. Characterized by multiple techniques, these composites show strong fluorescence and enhanced photostability, ideal for fluorescence imaging and sensing applications.

This study introduces a dual surfactant approach with CTAB and sodium oleate in the seed-mediated synthesis of the AuNBPs, which can significantly reduce the CTAB concentration to 10 mM. Additionally, optimal growth conditions are achieved by varying the volumes of seed solution, AgNO₃, and HCl. This work provides a framework applicable to the synthesis of other metallic nanomaterials.

This work introduces a novel method for producing small (≈11 nm), uniform Ni nanoparticles (Ni NPs), under mild conditions and in short times. These nanoparticles are stabilized in air by a protective capping layer (cetyltrimethylammonium bromide, CTAB). Epitaxial graphene samples functionalized with the synthesized Ni NPs exhibit thermal stability up to 550 °C, paving the way for advanced applications.

A kind of lipid nanoparticle containing rapamycin (LNP@rapa) is prepared. Following subcutaneous injection, LNP@rapa gains entry into lymph nodes via phagocytosis by immature dendritic cell (imDCs). Rapamycin's action involves the inhibition of imDC maturation by restraining the mammalian target of rapamycin (mTOR) pathway, culminating in costimulation blockade with T cells, and thus mitigating transplant rejection.

Green synthesis of hematite nanoparticles modulates their size, strain, optical, and photocatalytic properties. These nanoparticles act as visible light photocatalyst for dye degradation. Present study highlights that using commercially cheap starting materials and extract made from naturally available plant parts, materials having huge application potentials can be synthesized at low-cost by the simple green synthesis approach.

This study explores nanoparticle-assisted photothermal therapy by assessing gold nanorods (AuNRs) of various aspect ratios and surface functionalization as photothermal agents. In vivo positron emission tomography imaging highlights enhanced tumor accumulation of carboxylic acid-functionalized AuNRs, sufficient for effective hyperthermal cell death in a mouse breast cancer model.
