We present development of a compact and label-free sensor based on the surface modification of copper vapor laser fabricated long period fiber gratings for detection of airborne Aspergillus niger (A. niger) fungal spores. Surface of sensors were functionalized with monoclonal glucose oxidases IgG1 for target-specific covalent binding. In process of functionalization and binding of 10³ cfu/ml of pathogenic A. niger fungal spores, notable shorter wave transition in resonance wavelength from 1562.93 nm to 1555.97 nm, and significant reduction in peak loss from 61.72 dB to 57.48 dB were recorded. The implementation was cost effective and yielded instantaneous results.

我们目前正在开发一种基于铜蒸气激光制造的长周期光纤光栅的表面改性的紧凑且无标签的传感器，用于检测机载黑曲霉（A. niger）真菌孢子。传感器表面用单克隆葡萄糖氧化酶IgG1功能化以实现靶标特异性共价结合。在功能化和结合10 ³  cfu / ml致病性黑曲霉真菌孢子的过程中，记录到共振波长从1562.93 nm到1555.97 nm明显更短的波跃迁，峰损失从61.72 dB显着降低到57.48 dB。该实施具有成本效益，并产生了即时结果。
