We report in this communication a ready-to-use fused deposition modeling (FDM) based 3D-printed spectroelectrochemical cell to perform for the first time voltammetry of immobilized microparticles (VIMP) and Raman spectroscopy in situ using acrylonitrile butadiene styrene (ABS) as the filament material for printing. The 3D-printed cell was applied to evaluate solid state electrochemical behavior of tadalafil as a proof-of-concept. Several advantages were achieved in the use of the developed device, such as less manipulation of the working electrode, monitoring the same region of the solid microparticles before and after electrochemical measurements, better control of the laser incidence, low-cost and low-time production. Furthermore, the device was printed in a single-step, without handling to assembly and it has an estimated material cost of approximately 2 $. The use of 3D-printing technology was significantly important to integrate Raman spectroscopic method with VIMP measurements and to support mechanism elucidation and characterization of the compounds with less manipulation of the working electrode, avoiding loss of solid products formed from electrochemical reactions.

用于固定微粒和拉曼光谱的原位伏安法的即用型 3D 打印电化学电池

我们在此通讯中报告了一种即用型熔融沉积建模 (FDM) 基于 3D 打印的光谱电化学电池，首次使用丙烯腈丁二烯苯乙烯 (ABS) 作为固定化微粒 (VIMP) 和拉曼光谱进行原位伏安法用于印刷的长丝材料。应用 3D 打印电池来评估他达拉非的固态电化学行为，作为概念验证。使用开发的设备获得了几个优点，例如对工作电极的操作较少，在电化学测量前后监测固体微粒的同一区域，更好地控制激光入射，低成本和低时间生产. 此外，该设备是一步打印出来的，无需处理组装，预计材料成本约为 2 美元。3D 打印技术的使用对于将拉曼光谱方法与 VIMP 测量相结合，并支持对工作电极进行较少操作的化合物的机理阐明和表征，避免电化学反应形成的固体产物的损失，这一点非常重要。
