Development and Characterization of Copaiba Oil‐Loaded Polymeric Nanocapsules With Enhanced Antitumor Activity Against Breast Cancer Cells

open access: yesParticle &Particle Systems Characterization, Volume 43, Issue 1, January 2026.
The present study developed and characterized a novel copaiba oil polymeric nanoparticle (NPOC), which was efficiently internalized by breast cancer cells, exhibited greater cytotoxicity and selectivity than free copaiba oil and standard drug doxorubicin. NPOC also reduced tumor growth and migration in 3D models.

Optimizing fecal DNA collection and storage techniques for noninvasive genetic sampling of river otters

open access: yesWildlife Society Bulletin, Volume 49, Issue 4, December 2025.
This study compared 2 non‐invasive DNA collection methods for river otters and found that fecal swabbing consistently outperformed DETs buffer storage across both temperate and tropical environments. Swabbing yielded higher PCR and genotyping success rates while reducing genotyping errors, particularly when sampling anal jelly in tropical conditions ...
