This study investigates the use of photoluminescent amphiphilic porous silicon nanoparticles (αϕ-pSiNPs) as effective ultrasound (US) amplifiers for cancer sonodynamic theranostics. αϕ-pSiNPs were synthesized via a novel top-down approach involving porous silicon (pSi) films electrochemical etching, borate oxidation, and hydrophobic coating with octadecylsilane (C18), resulting in milling into nanoparticles with hydrophilic exteriors and hydrophobic interiors. These properties promote gas trapping and cavitation nucleation, significantly lowering the US cavitation threshold and resulting in selective destruction of cancer cells in the presence of nanoparticles.

Article Synopsis
  • * A survey involving 1,089 unvaccinated participants revealed that 59.7% had experienced COVID-19, with 47.1% of those exhibiting symptoms and 8.6% hospitalized, while 96.2% of asymptomatic cases were not reported.
  • * Findings indicate a link between older age and poor self-rated health with increased COVID-19 severity and hospitalization, emphasizing the need for better surveillance to detect asymptomatic infections.
