Article Synopsis
  • Recent advancements in nanomaterials, specifically hydroxyapatite (HAp) doped with rare-earth elements like Yb and Gd, have shown promise for bioimaging applications due to improved bioactivity and imaging properties.
  • The synthesis of Yb-Gd-HAp nanoparticles involved a wet precipitation method, followed by characterizing them for crystal structure, functional groups, and surface area, alongside the development of an imaging contrast agent by conjugating with IR783 dye and folic acid.
  • In vitro studies confirmed the biocompatibility of the nanoparticles, and photodynamic therapy was tested on MDA-MB-231 breast cancer cells, demonstrating effective photosensitizing properties and reactive oxygen species generation.

Introduction: The advanced features of plasmonic nanomaterials enable initial high accuracy detection with different therapeutic intervention. Computational simulations could estimate the plasmonic heat generation with a high accuracy and could be reliably compared to experimental results. This proposed combined theoretical-experimental strategy may help researchers to better understand other nanoparticles in terms of plasmonic efficiency and usability for future nano-theranostic research.

Injectability and self-setting properties are important factors to increase the efficiency of bone regeneration and reconstruction, thereby reducing the invasiveness of hard tissue engineering procedures. In this study, 63S bioactive glass (BG), nano-hydroxyapatite (n-HAp), alumina, titanium dioxide, and methylene bis-acrylamide (MBAM)-mediated polymeric crosslinking composites were prepared for the formulation of an efficient self-setting bone cement. According to the cytocompatibility and physicochemical analyses, all the samples qualified the standard of the bio-composite materials.

Article Synopsis
  • * Using a co-precipitation approach, researchers created Co-HAp by replacing calcium ions with cobalt, and various techniques were applied to confirm the successful doping and characterize the nanoparticles.
  • * Results showed that Co-HAp nanoparticles are non-toxic to breast cancer cell lines, have high drug loading capacity for doxorubicin (DOX), and exhibit enhanced fluorescence properties, making them suitable for drug delivery and imaging applications.

Imaging modalities combined with a multimodal nanocomposite contrast agent hold great potential for significant contributions in the biomedical field. Among modern imaging techniques, photoacoustic (PA) and fluorescence (FL) imaging gained much attention due to their non-invasive feature and the mutually supportive characteristic in terms of spatial resolution, penetration depth, imaging sensitivity, and speed. In this present study, we synthesized IR783 conjugated chitosan-polypyrrole nanocomposites (IR-CS-PPy NCs) as a theragnostic agent used for FL/PA dual-modal imaging.
