This paper comprehensively introduces the theoretical and practical background of Raman spectroscopy and its advanced variants. It highlights the various aspects of material characterization that Raman scattering can reveal and emphasizes its potential in biomedical material design and development. Additionally, practical recommendations on the integration of Raman techniques into the experimental laboratory toolbox are provided.
Raman spectroscopy is an analytical method based on light-matter interactions that can interrogate the vibrational modes of matter and provide representative molecular fingerprints. Mediated by its label-free, non-invasive nature, and high molecular specificity, Raman-based techniques have become ubiquitous tools for in situ characterization of materials. This review comprehensively describes the theoretical and practical background of Raman spectroscopy and its advanced variants. The numerous facets of material characterization that Raman scattering can reveal, including biomolecular identification, solid-to-solid phase transitions, and spatial mapping of biomolecular species in bioactive materials, are highlighted. The review illustrates the potential of these techniques in the context of active biomedical material design and development by highlighting representative studies from the literature. These studies cover the use of Raman spectroscopy for the characterization of both natural and synthetic biomaterials, including engineered tissue constructs, biopolymer systems, ceramics, and nanoparticle formulations, among others. To increase the accessibility and adoption of these techniques, the present review also provides the reader with practical recommendations on the integration of Raman techniques into the experimental laboratory toolbox. Finally, perspectives on how recent developments in plasmon- and coherently-enhanced Raman spectroscopy can propel Raman from underutilized to critical for biomaterial development are provided. The potential and benefits of Raman spectroscopy as an analytical method for non-invasive biomaterial characterization are presented. After a comprehensive description of the theoretical and practical background, the advantages of Raman spectroscopy are introduced through a selection of relevant examples from the literature. Practical recommendations on the integration of Raman techniques into the experimental laboratory toolbox are also discussed.image
