生物传感器(biosensor)是对生物物质敏感并将其浓度转换为电信号进行检测的仪器。生物传感器是由固定化的生物敏感材料作识别元件（包括酶、抗体、抗原、微生物、细胞、组织、核酸等生物活性物质）与适当的理化换能器（如氧电极、光敏管、场效应管、压电晶体等等）及信号放大装置构成的分析工具或系统，具有接受器与转换器的功能。目前，生物传感器已广泛应用于医学检测、食品毒性检测、工业加工和监测、农业应用、环境污染控制等方面。
    根据全球知名市场调研公司PMR（Persistence Market Research）近日发布的一份新报告，未来6年，全球生物传感器（biosensor）市场将经历快速增长，该市场2014市值为129亿美元，到2020年将达到225亿美元，复合年增长率（CAGR）为9.7%。按地理划分，北美是全球生物传感器的最大市场，2014年市值57亿美元，预计到2020年将达到95亿美元，预测期内复合年增长率（CAGR）为8.9%。而由于医疗保险普及率的不断扩大、人口基数大以及卫生保健系统的不断升级，亚太地区将成为增长最快的地区。
    根据报告内容，由于即时检验(point-of-care testing,POCT)需求的不断增加，全球生物传感器市场正经历显著增长。慢性病及生活方式相关疾病发病率上升、不断增长的老龄人口、生物传感器在各行业的广泛应用、纳米技术在医疗保健领域的应用，帮助推动了全球生物传感器市场的快速增长。此外，个性化药物和非侵入性生物传感器的出现及不断增长的需求，也将驱动全球生物传感器市场增长。然而，医疗系统中严格的监管要求和报销政策将限制市场的增长，同时该领域的监管程序也未跟上新医疗技术的快速发展的步伐。
    按技术划分，生物传感器市场包括电化学、光学、压电、热敏电阻；其中，电化学生物传感器是生物传感器中最常用的技术，而光学生物传感器将成为增长最快的技术类型。按应用划分，生物传感器市场可分为医疗诊断、食品毒性检测、农业检测、工业过程控制和环境污染控制等，其中医疗诊断是生物传感器最流行的应用领域，而医疗诊断中即时检测（POCT）是生物传感器应用最多的领域。按终端用户划分，生物传感器市场可分为即时检测（POCT）、家庭保健诊断、研究实验室、安全和生物防御，其中安全和生物防御将成为增长最快的终端用户类型。
    报告指出，全球生物传感器市场的主要参与者包括：雅培（Abbott）、西门子医疗、Nova Biomedical公司、拜耳、强生、美敦力、罗氏等。（药家网yaojia.org）
