Abstract:   (910 Views)

In order to achieve high resolution, nanomaterial which acquire intrinsic NIR responsive optical properties, biocompatibility, and flexibility are being used. Recently, the novel nanomaterials such as nanorods, nanocube and nanocages have been investigated. Their results represented a LSPR peak in NIR range with absorption cross section of around 7.26-8.10 ×[10^(-15)  m^2]. Employing higher density of nanoparticles is one of the most prevalent mechanisms of signal enhancement. However, its utilization has been limited due to high operation cost and uncontrolled condition. On the other hand, novel nanomaterials have been developed to overcome aforementioned efforts. In this study, a plasmonic star shaped nanoprobes with strong raman scattering signal and less cellular damage for intracellular imaging are designed, and the description of the use of plasmonics surface-enhanced Raman scattering (SERS) probes for the detection of diseases is provided. The responses presented that nanostars showed an extremely strong plasmon resonance peak of around 15×[10^(-15)  m^2] ,that We can control plasmon resonance peak in NIR region.
