The coronavirus disease 2019 (COVID‐19) caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is considered as serious global threat of this time and greatest challenge for recent days. Several approaches have been carried out in this direction to fight against COVID‐19. Among these, nanotechnology is one of the promising approach to face these challenges in the current situation. Recently, graphene‐based nanomaterials have been explored for COVID‐19 due to its unique physicochemical properties. This mini review provides a recent progress in graphene‐based nanomaterials and its applications for diagnosis, detection, decontamination, and protection against COVID‐19. Further, main challenges and perspective for fundamental design and development of technologies based on graphene‐based materials are discussed and suitable directions to improve these technologies are suggested. This article will provide timely knowledge and future direction about this wonder materials in various biological applications.

Decarboxylative carbamoylation of heteroarenes using oxamic acids under visible-light irradiation is described.

Visible-light-promoted addition of α-bromoaceto­phenones onto the cyclopropene π-system in the presence of the fac-Ir­(ppy)3 catalyst was shown to afford the corresponding 1­(4H)-naphthalenones. The syn-carboarylation of the cyclopropene is followed by a cyclopropane ring opening under the basic conditions, allowing the formation of two C–C bonds and the generation of 1­(4H)-naphthalenones bearing an all-carbon benzylic quaternary stereocenter.
