Complexes of cobalt nanoparticles and polyfunctional curcumin as antimicrobial agents

Curcumin-reduced graphene oxide sheets and their effects on human breast cancer cells

“…It should be noted that after addition of curcumin into the GO solution, the peak related to curcumin at 420 nm disappeared. This can be assigned to attachment of the chromophore sides of curcumin onto the rGO surfaces [53]. These results indicates reduction of GO by curcumin.…”

A Review on Antibacterial, Antiviral, and Antifungal Activity of Curcumin

“…Complexes of curcumin with cobalt nanoparticles showed increased antibacterial activity against E. coli [51]. Additionally, fabrication of silver nanocomposite films impregnated with curcumin showed the stronger antibacterial activity against E. coli .…”

Conjugation of curcumin with PVP capped gold nanoparticles for improving bioavailability

“…Toxicity analysis was done using MTT assay as described elsewhere [31]. and C\O\C (1000-1300 cm −1 ) typically attributed to symmetric and asymmetric configurations of C\O\C chains [11]. Spectrum (iii) illustrates the functionalization of citrate reduced gold NPs with PVP in the form of shift of C_O stretching from 1660 cm −1 to 1628 cm −1 .…”

“…2 shows the UV-vis spectra of (i) curcumin in PVP (ii) PVP functionalized gold nanoparticles and (iii) PVP functionalized gold nanoparticles with curcumin in aqueous media. UV-vis spectrum of curcumin in PVP shows an absorption peak at~415 nm which is the signature of basic diaryl heptanoid chromophore group of curcumin [11]. The spectrum of PVP functionalized gold nanoparticles (ii) shows absorption peak at~520 nm, which is a characteristic peak of gold nanoparticles arising due to Surface Plasmon Resonance (SPR) [33].…”

“…Nanoparticles [11,12], liposomes [13], micelles [14] and phospholipid complexes [15] are being used to improve the bioavailability of curcumin.…”
