Abstract

Organic semiconductors (OSCs) are one of the most promising candidates for flexible, wearable and large-area electronics. However, the development of n-type OSCs has been severely held back due to the poor stability of their most candidates, that is, the intrinsically high reactivity of negatively charged polarons to oxygen and water. Here we demonstrate a general strategy based on vitamin C to stabilize n-type OSCs, remarkably improving the performance and stability of their device, for example, organic field-effect transistors. Vitamin C scavenges reactive oxygen species and inhibits their generation by sacrificial oxidation and non-sacrificial triplet quenching in a cascade process, which not only lastingly prevents molecular structure from oxidation damage but also passivates the latent electron traps to stabilize electron transport. This study presents a way to overcome the long-standing stability problem of n-type OSCs and devices.

Abstract

Objective To discuss the influence and significance of stromal cell- derived factor 1 (SDF -1) and its specific receptor CXC chemokine receptor 4 (CXCR4) in proliferation, migration and invasion ability of SW480 colorectal cancer cells. Methods The colorectal cancer cell line SW480 in logarithmic phase was divided into four groups: control group (with no any processing), SDF-1 group (added 100 µg/L SDF-1), SDF-1 + 1 mg/L AMD3100 mixed group (added 1 mg/L AMD3100 for 2 hours, then added 100 µg/L SDF-1) and AMD3100 group (added 1 mg/L AMD3100). Immunohistochemistry method was used to detect the protein expression of CXCR4 in SW480 cells. The expression of CXCR4 mRNA in SW480 cells was detected by RT-PCR before and after SDF-1 and AMD3100 treatment. MTT assay and transwell chamber were used to test the changes of proliferation, migration and invasion ability of SW480 cells before and after SDF-1 and AMD3100 treatment. Results The result of immunohistochemistry showed that CXCR4 protein was expressed in SW480 cells (positive rate=80%). CXCR4 mRNA was expressed in SW480 cells. The expression of CXCR4 mRNA was up-regulated by SDF-1(100 µg/L), which could be inhibited by AMD3100 (1 mg/L). The proliferation activity was higher in SDF-1 group (0.847±0.039) compared to that in control group (0.624±0.011) and SDF-1 + AMD3100 mixed group (0.607 ±0.016). The proliferation activity was lower in AMD3100 group (0.456±0.031) than that in control group and SDF-1 + AMD3100 mixed group (F=108.03, P<0.05). The number of transmembrane cells was more in SDF-1 group (98.7±5.8, 33.7±6.2) than that in control group (21.0±2.2, 6.1±2.3), SDF-1 + 1 mg/L AMD3100 mixed group (18.5±8.4, 8.5±2.8) and AMD3100 group (12.1±3.2, 2.1±1.0) detected by transwell chamber experiment. However, there were no statistical differences between three groups. Conclusion The biological axis SDF- 1/CXCR4 can promote the proliferation, migration and invasion in colorectal cancer cell line SW480. [ABSTRACT FROM AUTHOR]
