Shape-engineered gold nanoparticles (AuNPs) offer advanced sentinel lymph node (SLN) mapping for cancer staging. These versatile nanoparticles overcome limitations of conventional tracers, enabling multimodal imaging and theranostic applications.

Area of Science:

Nanotechnology and Biomedical Imaging
Oncology and Surgical Navigation

Background:

Sentinel lymph node (SLN) mapping is critical for accurate cancer staging and guiding surgical interventions.
Current SLN mapping methods using dyes, radiocolloids, or fluorescence tracers have limitations in resolution, penetration depth, and single-modality detection.

Purpose of the Study:

To review the application of shape-engineered gold nanoparticles (AuNPs) for enhanced SLN mapping.
To explore how AuNP properties influence lymphatic transport, nodal retention, and imaging capabilities for improved cancer management.

Main Methods:

Review of various shape-engineered AuNP platforms (nanospheres, nanorods, nanostars, nanocages, nanoclusters, hybrid assemblies) for SLN mapping.
Analysis of how AuNP shape, size, and surface characteristics impact lymphatic system interaction and signal generation.

Keywords:

Discussion of multimodal imaging potential including CT, photoacoustic, Raman, nuclear, and MRI.

Main Results:

Gold nanoparticles (AuNPs) demonstrate tunable properties for multimodal imaging and theranostic functions in SLN mapping.
Particle engineering allows optimization of lymphatic transport, retention within lymph nodes, and signal characteristics for various imaging modalities.
Shape and surface modifications are key to enhancing performance and overcoming limitations of conventional SLN tracers.

Conclusions:

Shape-engineered AuNPs represent a promising platform for advanced SLN mapping, offering superior imaging and theranostic capabilities.
Further research into multimodal design strategies and safety is crucial for the clinical translation of AuNP-based SLN mapping technologies.
