Randomized trial demonstrates apoptotic death in lung adenocarcinoma cells using silver nanoparticles, highlighting therapeutic potential.

This study aims to investigate the effects of silver nanoparticles synthesized from Leptolyngbya valderiana on lung adenocarcinoma cells.
Synthesized silver nanoparticles (AgNPs) from Leptolyngbya valderiana using 0.01 M AgNO3 for 72 hours.
Characterized the nanoparticles' size and structure, averaging 50 ± 21.4 × 39 ± 14 nm with a specific absorption peak at 3 keV.
Evaluated the antiproliferative effects on A549 lung cancer cells and normal cell lines BEAS-2B and HEK-293.
AgNPs demonstrated an IC50 value of 19.78 ± 1.296 μg/mL against A549 cells, indicating potent antiproliferative activity.
Microscopic evaluation revealed increased cell death with prominent nuclear fragmentation in A549 cells.
Flow cytometric analysis indicated enhanced sub-G0 phase population, suggesting G0/G1 phase arrest in treated cells.
