Nanoscale lipid vesicles functionalized with nitro-aniline derivative for photoinduced nitric oxide (NO) delivery
Nanoscale vesicles functionalized with nitric oxide (NO) releasing molecule 4-nitro-3-(trifluoromethyl)aniline has been reported. The new NO-nano vesicular donor material shows an effective photo release of NO upon irradiation with blue light at 410 nm. The kinetics of NO release has been monitored by using simple spectroscopic techniques such as UV-Vis and fluorescent method. Colorimetric Griess assay and fluorescence DAF assay have been used for the detection and quantification of NO released from vesicles. This new vesicular nanoscale NO donor has the advantages of facile preparation in water, capable of releasing NO under pure aqueous medium, photo-controlled NO release, bio-compatibility as well as capacity to modulate the NO donor loading to achieve essential amount of NO.
