Biosensors are analytical tools that can be used as simple, real-time and effective devices in clinical diagnosis, food analysis, and environmental monitoring. In the last years, electrospun nanofiber’s engineering has emerged as a possible strategy to improve the performance of biosensor devices. These nanostructures present a high surface-to-volume ratio, interconnected porous structure, low barrier to diffusion, and adjustable surface functionality. Additionally, nanofibers have also been demonstrated to work efficiently as platforms to immobilize biomolecules, providing a suitable microenvironment to biologically active molecules, which is beneficial for biosensing performance. This review aims to highlight the different strategies (e.g., adsorption, covalent binding, entrapment, and imprinting) for immobilizing functional receptors onto nanofibers surface for the development of specific and sensitive (bio)chemical assays, which can be used for a wide range of applications. The attractive features of electrospun nanofibers and the biorecognition elements properties are also presented and discussed. Finally, the current challenges and future opportunities for the design of nanofiber-based biosensing interfaces are also addressed. |

Upland rice is the main rice cropping system in Brazil and represents 70% of the total rice cultivated area. Rice is present in all states, and considered the most important crop in the southern, west-central, and northern regions. While several rice cropping systems are practiced in Brazil, the most commonly used are the irrigated lowland rice, lowland rice, upland rainfed rice, and favored upland rainfed rice systems. Favored upland rainfed rice is cultivated under sprinkler irrigation or in regions with good rainfall distribution with no risk of water stress and represents about 20% of the total upland rice area. Upland rainfed rice is usually cultivated in areas with higher risks of drought spells and where artificial irrigation is not a common practice. |
