Graphical Abstract
  • . Furthermore, they require only small quantities for utilization [8]. Several types of nanoparticles have been employed as carriers for rhizobacteria inoculants, including silica nanoparticles [9], clay nanoparticles [8], carbon nanoparticles [10], zinc oxide nanoparticles [11], and calcium carbonate

Conclusion Nanohydroxyapatite (nHA) was synthesized successfully using a hydrothermal method, and XRD analysis confirmed its alignment with the ICSD standard #154781. The measured crystal size of nHA was 34.27

This sensitivity facilitates diverse therapeutic effects and offers solutions to complex ophthalmic diseases. In

This targeted approach ensures that the laser energy remains below the threshold that could damage healthy cells, and the thermal field is efficiently confined to a 10 nm range around the cancer cells, thereby sparing
