Article Synopsis
- Hydroxyapatite is commonly used in medicine for repairing and regenerating tissues, and doping it with silver enhances its antimicrobial properties.
- In the study, various types of silver-doped nanohydroxyapatite were synthesized and analyzed, confirming their hydroxyapatite structure and the presence of essential elements through several scientific techniques.
- The results indicated that silver-doped hydroxyapatite nanoparticles exhibit significant antibacterial and antifungal activity against various bacterial and fungal strains compared to pure hydroxyapatite.
The aim of this research was to investigate the photothermal ability of nanocrystalline hydroxyapatite (nHAp) incorporated with silver and gold. It was studied by using a recently developed technique evaluating the photothermal conversion efficiency. The heating performance of aqueous dispersions was examined under 445 and 532 nm excitation.

- - Anthrax is a recurring zoonotic disease in Ukraine, with frequent outbreaks in certain areas, and this study aimed to identify the circulating genotypes by analyzing four strains from different regions.
- - The researchers used advanced sequencing techniques to accurately reconstruct the genomes of these strains, determining they belong to a specific subgroup that is endemic to the region, indicating a shared ancestry.
- - The findings underscore the need for improved surveillance and prevention strategies against anthrax, especially in light of predictions that climate change could lead to increased outbreak occurrences in the future.
Composite materials based on hydroxyapatite are widely used for bone tissue engineering. There is evidence of a positive effect of the presence of strontium in osteoplastic materials in the case of a Ca/Sr certain ratio. To examine the effect of the addition of Sr, a study was made by introducing it into the material composition based on biogenic hydroxyapatite and sodium borosilicate glass (50/50% wt.

It was established that the solubility of the composites on the basis of synthetic calcium phosphates and glass after 2 and 7 days contact with saline composites is the highest among the materials under study. First of all, this fact is related to the peculiarities of their phase composition, high fraction of open porosity, and high permeability.
