Dynamic structuralcolors can change in response todifferent environmental *** ability remains effectiveeven when the size of the speciesresponsible for the structural coloris reduced to a few micrometers,providing a promising sensingmechanism for solving microenvironmentalsensing problems inmicro-robotics and ***, the lack of dynamicstructural colors that can encoderapidly, easily integrate, and accuratelyreflect changes in physical quantities hinders their use in microscale sensing applications. Herein, we present a 2.5-dimensionaldynamic structural color based on nanogratings of heterogeneous materials, which were obtained by interweaving a pH-responsive hydrogelwith an IP-L photoresist. Transverse gratings printed with pH-responsive hydrogels elongated the period of longitudinal grating in the swollenstate, resulting in pH-tuned structural colors at a 45° incidence. Moreover, the patterned encoding and array printing of dynamic structuralcolors were achieved using grayscale stripe images to accurately encode the periods and heights of the nanogrid structures. Overall, dynamicstructural color networks exhibit promising potential for applications in information encryption and in situ sensing for microfluidic chips.

Isolation and Characterization of Radiation-resistant Lung Cancer D6-R Cell Line

引用

Biomedical and Environmental Sciences 2008年第4期21卷 339-344页

作者： QI-chun WEI LI SHEN SHU zheng yong-LIANG ZHU Ministry of Education Key Laboratory of Cancer Prevention and Intervention Zhejiang University Hangzhou 310009 Zhejiang China Department of Radiation Oncology the Second Affiliated Hospital Zhejiang University School of Medicine Hangzhou 310009 Zhejiang China

Objective To isolate an isogenic radioresistant cancer cell line after fractioned X-ray radiation and characterize the resistant cells. Methods D6 cells were exposed to repeated X-ray irradiation, and after a total dose of 5200 cGy in 8 fractions, a radioresistant monoclone D6-R was obtained. The radiosensitivity and drug sensitivity of the novel radioresistant D6-R cells, together with their parent D6 cells, were measured using clonogenic assay and MTT assay respectively. Cell cycle distribution was analyzed by flow cytometry. Fluorescence microscopy and flow cytometry were applied for apoptosis detection Comet assay was used for the detection of DNA damage and repair. Results D6-R cells showed higher and broader initial shoulder （D0=2.08 Gy, Dq=1.64 Gy, N=2.20） than the parent D6 cells （D0=1.84 Gy, Dq=0.34 Gy, N=1.20）. They were 1.65-fold more radioresistant than D6 cells in terms of SF2 （63% vs 38%） and were more resistant to ADM （3.15-fold） and 5-FU （3.86-fold） as compared with the latter. It was found that D6-R cells had higher fractions of cells in S phase （53.4% vs 37.8%） and lower fractions of cells in G1 （44.1% vs 57.2%） and G2-M phase （2.5% vs 5%）. There was no difference in radiation-induced apoptosis between D6-R and D6 cells. D6-R cells showed less initial DNA damage and increased capacity in DNA repair after irradiation, as compared with the parent cells. Conclusions D6-R cells have been isolated by exposing the parental D6 cells to repeated irradiation. The difference in cell cycle pattern together with the induction and repair of DNA damage might, at least partially, explain the mechanism of the radioresistance.
