February 2022 in “Pharmaceuticals” This study found that smaller curcumin nanocrystals (60 nm) enhanced transdermal and transfollicular penetration more effectively than larger sizes, influenced by particle size.
April 2026 in “BMC Biotechnology” This study found that curcumin spanlastics demonstrated greater antimicrobial, antioxidant, and anticancer activities in the MCF-7 breast cancer cell line compared to curcumin alone or curcumin nanocrystals, also affecting several cancer-related protein markers and showing enhanced solubility and activity.
