Bone defect therapy frequently encounters bacterial infections and chronic inflammation, which impair bone regeneration and threaten implant stability. Iron oxide nanoparticles have attracted attention due to cost-effectiveness, biocompatibility, and metabolic safety. However, iron oxide nanoparticles still struggle to balance low-temperature efficient antibacterial activity, effective immunomodulation, and bone regeneration.

This study focuses on tripartite synthesis of Silver (AgNPs), Mesoporous Silica (MSNs), and Hydroxyapatite (n-HAp) nanoparticles with aqueous extract of Cissus quadrangularis (Veldt grape plant; Indian name: Pirandai) as a reducing agent. The dried and powdered form of the plant was subjected to aqueous extraction. The phytochemicals analysis was qualitatively estimated which detected the presence of alkaloid, tannin, phenol, terpenoid, steroid and saponin.

Dentin caries is a multifactorial pathological process characterized by bacterial colonization and biofilm formation that result in concurrent acid-mediated demineralization and matrix metalloproteinase (MMP)-mediated degradation of the collagenous matrix. While remineralization therapies offer minimal invasiveness, their long-term efficacy is compromised by ongoing collagen degradation and persistent bacterial acid production that counteract remineralization efforts. To address these limitations, we designed PAMAM-G4@EG (PGE) nanoparticles (NPs) using polyamide amine (PAMAM) dendrimers as mineral deposition templates, with antimicrobial peptide G(IIKK)I-NH (G4) grafted onto the external surface groups and epigallocatechin gallate (EG) encapsulated within the internal cavities to provide biofilm disintegration and collagen protection for comprehensive dentin caries intervention.

Objectives: To investigate the physicochemical properties, in vitro efficacy, and in vivo therapeutic potential of novel tree turmeric root and nano-hydroxyapatite (TRE@NHA) composites in mitigating chemotherapy-induced peripheral neuropathy (CIPN).
Materials And Methods: TRE@NHA composites were synthesized and characterized using FTIR, XRD, TGA, and HRTEM. In vitro studies using PC12 cells assessed cytotoxicity, anti-inflammatory effects, and neuroprotective properties.

Neodymium (Nd³⁺) doped hydroxyapatite nanoparticles (Han: Nd³⁺ NPs) were synthesized and systematically characterized to evaluate their structural and functional properties for biomedical applications. X-ray diffraction (XRD) confirmed the crystalline phase retention post-doping, while x-ray photoelectron spectroscopy (XPS) revealed the successful incorporation of Nd³⁺ ions. The doping altered the optical and electronic properties, potentially enhancing bioactivity and imaging capabilities.
