Fabrication of CPI-410S-Based Photonic Devices

Check if the same lab product or an alternative is used in the 5 most similar protocols

CPI-410S was supplied by San-Apro Ltd. and used without further purification. The structure of CPI-410S is shown in the Supporting Information, Fig. S1. OTS and Acid Red 1 were purchased from Sigma Aldrich-Merck Co. Dimethyl sulfoxide, chloroform, n-hexane, and ethanol were purchased from Wako Pure Chemicals Co. Ltd. and used without further purification. Water was purified by reverse osmosis and deionization prior to use (Merck Millipore, Milli-Q Integral 3). Cellulose chromato graphy papers (Advantec Co., Ltd.) were immersed in 0.1% (v/v) OTS n-hexane solution for 5 min at room temperature. The papers removed from the OTS solution were rinsed with n-hexane and ethanol and dried in air. Subsequently, the OTStreated papers were immersed in chloroform and 5% (w/w) CPI-410S DMSO solution for 1 and 2 min, respectively. A diode laser (405 nm, 300 mW, Changchun New Industries Optoelectronics Technology Co., Ltd., MDL-III-405-300) and a xenon lamp (150 W, Hamamatsu photonics K.K., L2274) were used as an excitation light source for CPI-410S. A Galvo mirror system (Thorlabs, Inc., GVS002) was used to scan the laser beam.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
