Plasmonic-assisted zero-buffer Raman (PZBR) is a type of Raman spectroscopy system that utilizes surface plasmons to amplify the Raman signal. In this technique, a thin layer of surface plasmon is placed between the sample and the detector surface, enabling an increased signal amplitude at room temperature. Because of its ability to enhance the Raman signal, PZBR is gaining widespread acceptance in a number of applications.

One of the primary application fields of PZBR is in the study of ultra-trace and surface-sensitive samples. For example, PZBR has been used to study samples at ultra-trace concentrations in both biomedical and environmental studies. In these studies, the amplified Raman signal enabled researchers to detect and analyze samples at low concentrations that were not detectable using conventional methodologies.

PZBR can also be used to study heavily solvated samples. Because of its unique signal enhancement capability, PZBR enables researchers to study solvated samples with improved sensitivities. Furthermore, the use of a surface plasmon layer also enables the imaging of samples in fields such as life sciences, drug delivery, and material characterization. By imaging samples using PZBR, researchers can directly observe microscopic details in samples that could not otherwise be observed.

The working principle of PZBR is based on the concept of surface plasmon resonance (SPR). In SPR, photons are incident on the surface of the sample, which excites electrons in the sample material to form a plasmon wave. As the photons continue to travel through the sample, they interact with other particles and the plasmons, resulting in an amplified Raman signal that is detectable by the detector.

The signal enhancement in PZBR is due to the interaction between the plasmonic layer and the sample material. As the photons scatter off of the sample material, they undergo an intensity transfer to the plasmonic layer, which increases the signal amplitude. Moreover, the plasmonic layer acts as a buffer between the sample and the detector, further increasing the signal enhancement.

Overall, PZBR is an emerging field of Raman spectroscopy that offers several advantages over traditional Raman techniques. With its ability to amplify trace samples and image microscopic features, PZBR can provide researchers with valuable insight into the structure and behavior of materials. Furthermore, with its unique buffer layer, PZBR can enable the study of solvated samples with increased sensitivity and accuracy.
