Plasmonically Enhanced Galactoxyloglucan Endowed Gold Nanoparticles Exposed Tumor Targeting Biodistribution Envisaged in a Surface-Enhanced Raman Scattering Platform
2017
Biopolymer capped gold nanoparticles (AuNPs) were perceived for tracing biodistribution in a solid tumor mice through surface-enhanced Raman scattering (SERS) fingerprinting. In this strategy, a robust and ecofriendly green chemistry approach was adopted to construct galactoxyloglucan (PST001) endowed AuNPs (PST-GNPs) with cancer-cell-selective toxic nature and excellent biocompatibility. Plasmonically enhanced light scattering properties facilitated PST-GNPs to be a superior SERS substrate with high Raman signal enhancement. In this context, PST-GNPs were scrutinized for the non-invasive label-free SERS live cell spectral imaging to evaluate the fingerprint molecular details of cellular processes. Consequently, the inherent SERS feature of PST-GNPs enabled us to investigate the dynamic and complex nature with NP biodistrubution in tumor-bearing mice on a SERS platform which illustrated the tumor targeting nature. Henceforth, the present findings emphasized a futuristic clinically relevant scenario for tr...
