“…A nanopillar is defined as an array of submicron-sized pillars composed of dielectrics, semiconductors, or metals. They have been used to develop advanced optical components such as flexible perovskite solar cells [16][17][18][19][20][21] and waveguide-coupled light-emitting diodes (LEDs) [22][23][24][25][26]. In cell-based assays, nanopillar (NP)-fabricated cell culture substrates are used to acquire valuable biological information from the membranes of cultured cells [27][28][29][30][31][32].…”

Nanopillars (NPs) are submicron-sized pillars composed of dielectrics, semiconductors, or metals. They have been employed to develop advanced optical components such as solar cells, light-emitting diodes, and biophotonic devices. To integrate localized surface plasmon resonance (LSPR) with NPs, plasmonic NPs consisting of dielectric nanoscale pillars with metal capping have been developed and used for plasmonic optical sensing and imaging applications. In this study, we studied plasmonic NPs in terms of their fabrication techniques and applications in biophotonics. We briefly described three methods for fabricating NPs, namely etching, nanoimprinting, and growing NPs on a substrate. Furthermore, we explored the role of metal capping in plasmonic enhancement. Then, we presented the biophotonic applications of high-sensitivity LSPR sensors, enhanced Raman spectroscopy, and high-resolution plasmonic optical imaging. After exploring plasmonic NPs, we determined that they had sufficient potential for advanced biophotonic instruments and biomedical applications.
