Protein Sensor

Recently, pattern-recognition-based protein sensing has received considerable attention because it offers unique opportunities that complement more conventional antibody-based detection methods. Here, we report a multichannel pattern-recognition-based sensor using a set of fluorophore-conjugated single-stranded DNAs (ssDNAs), which can detect various proteins. Three different fluorophore-conjugated ssDNAs were placed into a single microplate well together with a target protein, and the generated optical response pattern that corresponds to each environment-sensitive fluorophore was read via multiple detection channels. Multivariate analysis of the resulting optical response patterns allowed an accurate detection of eight different proteases, indicating that fluorescence signal acquisition from a single compartment containing a mixture of ssDNAs is an effective strategy for the characterization of the target proteins. Additionally, the sensor could identify proteins, which are potential targets for disease diagnosis, in a protease and inhibitor mixture of different composition ratios. As our sensor benefits from simple construction and measurement procedures, and uses accessible materials, it offers a rapid and simple platform for the detection of proteins.

Virtual prototyping technology as a key technology for agile manufacturing can deal with multidisciplinary knowledge across different fields. In the complex product development process, the exchange between heterogeneous data in heterogeneous environment is a universal problem encountered, which increases the complexity of collaborative parallel design of virtual prototype. Taking the product models as carriers and the different function requirements as clues, the knowledge structure and expression of product information in various fields was studied. By adopting component object model technology, direct geometry access technology, behavioural modeling technology and parametric design thinking, the interaction among tools in various function units was realized, and the effective integration of information and function in multi-fields was accomplished, the parameter-driven virtual prototype architecture of complex product based on the integration of information and function was created. The feasibility of this architecture has been verified by the actual engineering. This plan provides an effective way to carry out virtual prototype projects for enterprise.
