Low dimensional materials have attracted great research interest from both theoretical and experimental point of views. These materials exhibit novel physical and chemical properties due to the confinement effect in low dimensions. The experimental observations of graphene open a new platform to study the physical properties of materials restricted to two dimensions. This featured article provides a review on the novel properties of quasi one‐dimensional (1D) material known as graphene nanoribbon. Graphene nanoribbons can be obtained by unzipping carbon nanotubes (CNT) or cutting the graphene sheet. Alternatively, it is also called the finite termination of graphene edges. It gives rise to different edge geometries, namely zigzag and armchair, among others. There are various physical and chemical techniques to realize these materials. Depending on the edge type termination, these are called the zigzag and armchair graphene nanoribbons (ZGNR and AGNR). These edges play an important role in controlling the properties of graphene nanoribbons. The present review article provides an overview of the electronic, transport, optical, and magnetic properties of graphene nanoribbons. However, there are different ways to tune these properties for device applications. Here, some of them, such as external perturbations and chemical modifications, are highlighted. Few applications of graphene nanoribbon have also been briefly discussed.

In recent pandemic period it becomes very important to provide a detection technique which will offer high sensitivity, selectivity with low limit of detection. Optical biosensors provide an intriguing path for continuous and rapid detection of target analyte in order to enhance health outcomes. In these recent years nanomaterials have been largely focused in order to design highly efficient biosensors. As Noble metal nanoparticles are well known for their unique properties like plasmonic property, superconductivity and biocompatibility, were extensively used in different scientific field. Noble metal like gold, silver and platinum nanoparticles are used in designing different biosensors. These biosensors were widely used in virus detection of different respiratory related health problems like COVID-19. In this mini review we addressed the optical biosensors fabricated by using noble metal nanomaterials which are used in rapid detection with highly sensitive and selective detection methods with low Limit of detection in recent pandemic period.

One of the most often credited materials for opening up new possibilities in the creation of next-generation biosensors is graphene oxide (GO). GO has good water dispersibility, biocompatibility, and high affinity for specific biomolecules due to the coexistence of hydrophobic domains from pristine graphite structure and hydrophilic oxygen containing functional groups, as well as properties of graphene itself that are partly dependent on preparation methods. The high signal output and a strong potential for rapid industrial growth rate, graphene-based materials, such as graphene oxide (GO), are receiving substantial interest in bio sensing applications. Some of graphene's most enticing qualities are its superior conductivity and mechanical capabilities (such as toughness and elasticity), as well as its high reactivity to chemical compounds. The existence of waves on the surface (natural or created) is another property/variable that has immense potential if properly utilized. Single cell detection can be performed by optical biosensors based on graphene. The present state of knowledge about the use of graphene for bio sensing is reviewed in this article. We briefly cover the use of graphene for bio sensing applications in general, with a focus on wearable graphene-based biosensors. The intrinsic graphene ripples and their impact on graphene bio sensing capabilities are extensively examined.
