Abstract: The utilization of deoxyribonucleic acid (DNA) in nanotechnology is a promising area of research wherein the distinct properties of DNA are exploited for the design and development of new materials and applications. The biodegradability and natural profusion of DNA makes it highly suitable for use in various fields. In this report, we have treated DNA as a bioligand, supported on functionalized magnetite for the grafting of palladium (Pd) nanoparticles to make Pd‐DNA bio‐nanocatalyst. The Pd‐DNA was subjected to Fourier‐transform infrared spectroscopy, field‐emission scanning electron microscopy, transmission electron microscopy, X‐ray powder diffraction, Brunauer–Emmett–Teller, energy dispersive X‐ray spectroscopy, vibrating sample magnetometry, X‐ray photoelectron spectroscopy, and inductively coupled plasma optical emission spectrometry analysis. The prepared Pd‐DNA was found to be highly efficient in catalyzing Suzuki–Miyaura cross‐coupling reaction with excellent yields when compared with commercially available palladium‐based catalysts. Also, the Pd‐DNA could be easily recovered from the reaction mass using an external magnet and recycled up to six times without substantial loss of activity. Furthermore, Felbinac, a non‐inflammatory drug, was synthesized in quantitative yields using the Pd‐DNA bio‐nanocatalyst.
