“…The gelation stage depends on temperature and pH since both parameters have a strong influence on hydrolysis and condensation [71]. When condensation reaches a critical point, gelation occurs, and while the viscosity of the solution is greatly increased, there are still zones in which the sol has not been polymerized yet and clusters of already condensed particles cross-linked together giving an intermediary between solids and liquid [72].…”

Surface Enhanced Infrared Absorption Spectroscopy and Surface Enhanced Raman Spectroscopy are analytic techniques that have not been massively adopted since there are issues that still need to be solved with regard to the nature of the signal enhancement substrates used. The sol–gel method for the obtention of ceramics provides an alternative for the production of said substrates. Ceramics are very wear- and heat-resistant, properties that can be used for their regeneration, and through the sol–gel method, ceramics can be produced with high purity as well as can be fashioned in many ways through different techniques, which can be helpful in the pursuit of reproducibility. This paper discusses the different advantages of sol–gel ceramics, their use in the electrospinning technique, and their application in infrared and Raman surface-enhanced spectroscopy.
