The Cu1.8Se/CuAgSe nanostructure was synthesized by a simple two-step process. Starting with the template of cubic Cu1.8Se nanoplate by precipitation method, Cu1.8Se/CuAgSe nanostructure and ternary CuAgSe were prepared through a rapid ion exchange reaction using various amount of AgNO3 at room temperature. The as-prepared samples were analyzed by XRD, SEM and DRS. It was found that Cu1.8Se/CuAgSe heterostructure and the pure CuAgSe phase were formed without changing the morphology, and these samples had efficient light absorption from UV light to near-infrared light region. Photocatalytic properties of these samples were evaluated by the degradation of Congo red under visible and near-infrared light. The Cu1.8Se/CuAgSe nanostructure showed enhanced photocatalytic activity due to the lower recombination of charge-carrier in the photodegradation process.

Objectives Varicose veins that cannot be seen with the naked eye can be easily detected with Near Infrared (NIR) light. With a minimally invasive procedure performed with NIR light guided, the need for reoperation is reduced, while optimal treatment of venous insufficiency and symptoms is provided. In this study, the detection of residual varicose veins after varicose vein surgery using NIR light and the results of treatment of sclerotherapy were investigated. Methods In this retrospective study, treatment and clinical outcomes of patients’ who underwent NIR light-guided foam sclerotherapy for Clinical-Etiology-Anatomy-Pathophysiology (CEAP) (C1, C2) stage residual varicose veins after surgical varicose treatment between 2014 and 2017 were examined. Data of patients who underwent foam sclerotherapy with NIR light were collected and analyzed. Results A total of 151 patients and 171 lower extremity varicose veins were treated with surgery. 55 (35.7%) of the patients were male, and 96 (62.3%) were female. Their age ranges from 20 to 64, with an average age of 45.38. 4 (2.6%) of the patients had phlebectomy. 137 of patients (90.7%) had ligation of perforated veins, phlebectomy, and great saphenous vein (GSV) stripping, 10 of patients (6.6%) had GSV stripping, perforating vein ligation, phlebectomy, and small saphenous vein (SSV) surgery. No residual leakage was observed in the controls of GSV, SSV, and perforating veins by duplex ultrasonography (DUS). In the first month after varicose surgery, an average of 1.64 ± 1.05 sessions of sclerotherapy was applied to patients with CEAP C1, C2 stage residual varicose veins. 70 patients had one session of sclerotherapy, 37 patients had two sessions of sclerotherapy, 20 patients had three sessions of sclerotherapy, and 11 patients had four sessions of sclerotherapy administrated. The need for complementary therapy was required for all female patients; 13 of the male patients did not require complementary sclerotherapy. While single-session sclerotherapy was applied to most male patients (32 (58.18%), 10 (18.18%) patients received two sclerotherapy sessions. After completing sclerotherapy, 7 (4.63%) patients had superficial venous thrombosis, and 13 (8.60%) patients had hyperpigmentation. Conclusion Surgical treatment is a safe and effective technique in venous insufficiency. Nevertheless, residual varicose veins may remain, and these can be detected noninvasively with NIR light. Foam sclerotherapy with NIR light is a minimally invasive and safe treatment method for small residual varicose veins after the operation. We think that sclerotherapy with NIR light as a complementary treatment is a practical, reliable, and demanding treatment for clinical improvement, especially in female patients.
