摘要:
The present invention provides instruments and methods for screening combinatorial libraries that addresses many of the problems encountered when using conventional instruments. For example, the disclosed instruments can measure mechanical properties of library members in rapid serial or parallel test format, and can perform tests on small amounts of material, which are easily prepared or dispensed using art-disclosed liquid or solid handling techniques. Compared to conventional instruments, the disclosed instruments afford faster sample loading and unloading, for example, through the use of disposable libraries of material samples.

A method for high throughput mechanical property and bulge testing of materials libraries. A plurality of samples on a substrate are monitored for their response to a force from a fluid.
摘要:
One aspect of the present invention provides instruments for measuring mechanical properties of a combinatorial library of materials. The instruments include at least one capacitor to which a member of a library of material samples is removably secured for testing; at least one voltage source for delivering one or more forces to each library member; and at least one sensing device for monitoring the response each library member to the one or more forces. Another aspect of the present invention provides methods of screening a combinatorial library of materials where the method monitors the responses of a plurality of samples on a substrate to a force induced by a capacitor.
摘要:
A rapid throughput method for the preparation, analysis or both of libraries of material samples is provided. According to the method, a plurality of samples is provided. Providing the plurality of samples can include a variety of sample formation techniques including, but not limited to, extruding, milling, compression preparation, rotary mixing, microcentrifugation, molding and casting. Preferably, the samples are solidified into a near net shape configuration appropriate for testing of properties or characteristics of the samples.
摘要:
An apparatus and method for carrying out and monitoring the progress and properties of multiple reactions is disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel. In situ monitoring of individual reaction mixtures provides feedback for process controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight.

摘要:
A library of material samples is screened for properties such as permeability. A library of material samples is provided. A stimulus such as an exposure to a permeate fluid is provided to each member of the library. A response of each of the material samples due to the stimulus is measured and the response, the stimulus or both are recorded and related to provide data. Thereafter, the data is analyzed to reach conclusions regarding the properties of the material samples.
