Multifunctional magnetic nanowires (MNWs) have been studied intensively over the last decades, in diverse applications. Numerous MNW-based systems have been introduced, initially for fundamental studies and later for sensing applications such as biolabeling and nanobarcoding. Remote sensing of MNWs for authentication and/or anti-counterfeiting is not only limited to engineering their properties, but also requires reliable sensing and decoding platforms. We review the latest progress in designing MNWs that have been, and are being, introduced as nanobarcodes, along with the pros and cons of the proposed sensing and decoding methods. Based on our review, we determine fundamental challenges and suggest future directions for research that will unleash the full potential of MNWs for nanobarcoding applications.
多功能磁性纳米线 (MNWs) 在过去几十年中得到了广泛的研究，应用领域多样。众多基于 MNWs 的系统已经被引入，最初用于基础研究，后来用于传感应用，如生物标记和纳米条码。MNWs 的远程传感用于认证和/或防伪不仅限于对其性质进行工程设计，还需要可靠的传感和解码平台。我们综述了作为纳米条码引入的 MNWs 的最新设计进展，以及所提出的传感和解码方法的优缺点。基于我们的综述，我们确定了基本挑战，并为研究提出了未来的方向，这将释放 MNWs 在纳米条码应用中的全部潜力。
