　　【化工仪器网科技前沿】在智能手机盛行的当下，不管是移动支付、线上交易，还是浏览信息，用户只需完成简单的诸如点击屏幕、扫码、输入数据等操作即可在分秒钟之内完成线上交易活动以及收看各类资讯。此外，手机还能做到实时地定位，方便人们的交通出行；全天候的天气预报，方便人们安排相应的农事活动；智能远程操控机械设备，方便工业生产活动随时开展······可以说，手机已经成为了人们工农业生产、生活的好帮手。

　　然而，即便如此，在大多数情况下，手机在人们的固有认知中都是以移动通讯设备这一形象出现的，也就是说，其主要功能还是通讯。但是，近日，中国农科院团队研发的一项新技术，赋予了手机一个新的功能——农药残留的快速检测。是的，你没听错，原本风马牛不相及的智能手机与农药残留检测竟然意外碰撞出了科学的火花，诞生出了只需5分钟即可完成农药残留快速检测的“黑科技”。这到底是怎么一回事呢？

　　据科技日报报道，近日，中国科学院农业质量标准与检测技术研究所“农业化学污染物残留检测及行为研究创新团队”经过多年来在农药残留快速检测技术领域的不断深耕，研发出了一项新的农药残留快检技术——借助于微信小程序拍照，用户便可在5分钟内完成多种农药残留检测，检测信息直接显示在手机上，内容可以在线分享。这就相当于手机扫码在线阅读小说一般，速度之快不禁令人大为惊叹！

　　看到这里，你或许会认为既然能在短短的几分钟之内即可完成农药残留的检测，看来农残快检实在不是什么难事。事实上，农药残留的检测过程并没有你想的那么简单。

　　农药残留问题由来已久。自我国农业产业化发展以来，为增加作物产量，防治病虫害，农业生产领域对农药、抗生素、激素这类外源物质的依赖性日渐增强。尽管这些物质在农业生产的保质保量方面发挥了重要的作用，但超量的外源物质也直接影响了作物的品质，致使农产品表面甚至于内里的农药残留问题愈发严重。而食用这些农药残留超标的农产品会给广大消费者的身体健康造成潜在的危害。因此，对农产品开展科学的农药残留检测，守护人们的餐桌安全既必须又迫切。

　　当前，常规的农药残留检测技术主要有光谱法、酶抑制法和色谱法。其中，色谱法又包括薄层色谱法、气相色谱法、气相色谱-质谱联用技术、高效液相色谱法。这些分析检测技术在农药残留检测方面发挥了重要的功效。然而，这些技术或多或少的存在检测周期长、分析成本高等缺陷，对于需要实现现场快速检测的食品监管部门来说仍有诸多不便。为此，众多农药残留快检技术应运而生，常见的有化学速测法、免疫分析法、酶抑制法和活体检测法等。此外，还有农药残留速测仪、农药残留速测卡(即农药残留快速检测试纸)等快检设备纷纷投入使用。

　　在上述新研究过程当中，研究团队基于免疫层析试纸条和人工智能技术，成功研制出了多种农药的胶体金快速检测试纸条，然后用条形码给每一张试纸条标识身份，再配套研制出可图像智能识别的读取软件，以此为基础，通过开发微信应用小程序，即可利用智能手机拍照读取农药残留检测数据，方便快捷。

　　可以看到，该项新技术是在现有快检技术的基础之上，结合人工智能以及智能图像识别技术的一次全新的尝试与探索，结果无疑振奋人心。目前，该整体系统已经可以应用于实际的检测中。此外，这一新技术还有望应用于兽药残留、真菌毒素、环境污染物的检测等领域，应用前景广阔。
