Despite the enormous development of instruments for analyzing a wide variety of compounds, applied in different fields such as health, environment or quality control, the demand for increasingly sensitive and selective techniques continues to grow. In this regard, efforts have been made to highlight more appropriate techniques. Electrochemical sensors based on molecularly imprinted polymers (MIPs) offer an interesting alternative since they allow reaching high sensitivity and selectivity and they are inexpensive and easily adaptable to miniaturization. The choice of the functional monomer in the synthesis of MIPs is based on its capacity to provide complementary interactions with the target molecules. The various excellent properties of chitosan, as a biosourced polymer, make it a promising alternative to conventional functional monomers. This review reports on the principle of the MIPs technique describing the different possible approaches in their synthesis. It aims to provide an overview of the value of using chitosan as a functional monomer by highlighting its applications in electrochemical sensors.

尽管用于健康，环境或质量控制等不同领域的用于分析多种化合物的仪器的巨大发展，对灵敏和选择性技术的需求仍在不断增长。在这方面，已经努力强调更合适的技术。基于分子印迹聚合物（MIP）的电化学传感器提供了一种有趣的替代方法，因为它们可以实现高灵敏度和选择性，并且价格低廉且易于适应小型化。MIP合成中功能性单体的选择基于其提供与靶分子互补相互作用的能力。作为生物来源的聚合物，壳聚糖的各种优异性能使其成为常规功能单体的有前途的替代品。这篇综述报告了MIPs技术的原理，该技术描述了其综合中的各种可能方法。通过突出其在电化学传感器中的应用，旨在概述使用壳聚糖作为功能单体的价值。
