We report a simple, low-cost, rapid, and mask-free method to fabricate two-dimensional (2D) and three-dimensional (3D) microfluidic chip for biological analysis researches. In this fabrication process, a laser system is used to cut through paper to form intricate patterns and differently configured channels for specific purposes. Bonded with cyanoacrylate-based resin, the prepared paper sheet is sandwiched between glass slides (hydrophilic) or polymer-based plates (hydrophobic) to obtain a multilayer structure. In order to examine the chip’s biocompatibility and applicability, protein concentration was measured while DNA capillary electrophoresis was carried out, and both of them show positive results. With the utilization of direct laser cutting and one-step gas-sacrificing techniques, the whole fabrication processes for complicated 2D and 3D microfluidic devices are shorten into several minutes which make it a good alternative of poly(dimethylsiloxane) microfluidic chips used in biological analysis researches.  相似文献

Longitudinal Associations of Identity Processing Styles With Prodiversity and Proequality Values in Adolescence

In adolescence, the formation of personal identity and values may be intertwined, since values are among the main issues considered when building one's identity. This study examined how sociocognitive strategies used in the process of identity formation were related with adoption of prodiversity and proequality values, which are critically important for socially diverse contemporary societies. Participants were 916 adolescents (51.4% females, M_age = 15.65, SD_age = 0.73 at baseline) involved in a three-wave longitudinal study with annual assessments. The results of cross-lagged analyses suggest that more rational and deliberate processing of self-relevant information is related to stronger adoption of prodiversity and proequality values over time. In turn, endorsement of prodiversity and proequality values is related to more rational and deliberate processing of self-relevant issues.  相似文献
