Biosensors are defined as analytical devices incorporating a biological material, a biologically derived material or a biomimic intimately associated with or integrated within a physicochemical transducer or transducing microsystem, which may be optical, electrochemical, thermometric, piezoelectric, magnetic or micromechanical (Turner et al., 1987; Turner, 1989). Biosensors & Bioelectronics is the principal international journal devoted to research, design, development and application of biosensors and bioelectronics. It is an interdisciplinary journal serving professionals with an interest in the exploitation of biological materials and designs in novel diagnostic and electronic devices including sensors, DNA chips, electronic noses, lab-on-a-chip and μ-TAS. Biosensors usually yield a digital electronic signal which is proportional to the concentration of a specific analyte or group of analytes. While the signal may in principle be continuous, devices can be configured to yield single measurements to meet specific market requirements. Examples of Biosensors include immunosensors, enzyme-based biosensors, organism- and whole cell-based biosensors. They have been applied to a wide variety of analytical problems including uses in medicine, biomedical research, drug discovery, the environment, food, process industries, security and defence. The design and study of molecular and supramolecular structures with molecular biorecognition and biomimetic properties for use in analytical devices is also included within the scope of the journal. Here the focus is on the complementary intersection between molecular recognition, nanotechnology, molecular imprinting and supramolecular chemistry to improve the analytical performance and robustness of devices.

生物傳感器被定義為一種分析設備，它結合了生物材料、生物衍生材料或仿生材料，與物理化學換能器或傳感微系統緊密相關或集成在其中，這些換能器或傳感微系統可以是光學的、電化學的、測溫的、壓電的、磁性的或微機械的（Turner 等人，1987 年；Turner，1989 年）。《生物傳感器與生物電子學》是一本主要的國際期刊，致力于生物傳感器和生物電子學的研究、設計、開發和應用。它是一本跨學科期刊，服務于對生物材料和新型診斷和電子設備設計開發感興趣的專業人士，包括傳感器、DNA 芯片、電子鼻、芯片實驗室和 μ-TAS。生物傳感器通常會產生與特定分析物或分析物組濃度成比例的數字電子信號。雖然信號原則上可能是連續的，但設備可以配置為產生單一測量值以滿足特定的市場需求。生物傳感器的例子包括免疫傳感器、基于酶的生物傳感器、基于生物體和整個細胞的生物傳感器。它們已應用于各種分析問題，包括醫學、生物醫學研究、藥物發現、環境、食品、加工工業、安全和國防。用于分析設備的具有分子生物識別和仿生特性的分子和超分子結構的設計和研究也屬于該期刊的范圍。這里的重點是分子識別、納米技術、分子印跡和超分子化學之間的互補交叉，以提高設備的分析性能和穩健性。
