    • A novel method is disclosed wherein polymerized crystalline colloidal array (PCCA) chemical sensing materials are used to detect the presence of certain chemical species in high ionic strength solutions, such as bodily fluids. The PCCA sensors consist of a mesoscopically periodic array of colloidal particles polymerized into a hydrogel. The array of colloidal particles diffracts light in the visible spectral region due to the periodic spacing of the particles. The PCCA materials also contain molecular recognition components that bind to the chemical species being detected. The binding or the chelation of the chemical species of interest results in a Donnan potential that swells the hydrogel and in turn red shifts the diffracted light proportionately to the concentration of the chemical species. However, no significant red shift response may occur for PCCA chemical sensors in high ionic strength solutions containing chemical species of interest. Thus, the method of the present invention provides for incubating the PCCA chemical sensor in the sample solution, subsequently exposing the PCCA to a low ionic strength solution, such as pure water, and measuring the transient diffraction shift response of the PCCA upon the exposure to the low ionic strength solution. The non-chelated or non-bound ions (such as salt ions in high ionic strength solutions) diffuse out of the PCCA hydrogel more quickly than the chemical species ions bound to the molecular recognition component. Thus, the resulting transient PCCA diffraction red shift is proportional to the concentration of the chemical species in the sample solution. The present invention also discloses using the PCCA chemical sensors in an optrode for detecting certain chemical species in high ionic strength solutions, such as bodily fluids.
    • 公开了一种新的方法,其中使用聚合的结晶胶体阵列(PCCA)化学感测材料来检测高离子强度溶液例如体液中某些化学物质的存在。 PCCA传感器由聚合成水凝胶的胶体颗粒的中视周期阵列组成。 由于颗粒的周期性间隔,胶体颗粒阵列在可见光谱区域衍射光。 PCCA材料还含有结合待检测化学物质的分子识别组分。 感兴趣的化学物质的结合或螯合导致Donnan电位,其使水凝胶膨胀,并且依次将衍射光与化学物质的浓度成比例地变换。 然而,在含有感兴趣化学物质的高离子强度溶液中,PCCA化学传感器不会发生显着的红移响应。 因此,本发明的方法提供了将PCCA化学传感器温育在样品溶液中,随后将PCCA暴露于低离子强度溶液(例如纯水),并测量了PCCA在曝光后的瞬态衍射平移响应 低离子强度溶液。 非螯合或非结合离子(如高离子强度溶液中的盐离子)比与分子识别组分结合的化学物质离子更快地扩散出PCCA水凝胶。 因此,所得到的瞬时PCCA衍射红移与样品溶液中化学物质的浓度成比例。 本发明还公开了将PCCA化学传感器用于检测诸如体液的高离子强度溶液中的某些化学物质的光学特性。

    • Novel sensor devices composed of a crystalline colloidal array (CCA) polymerized in a hydrogel are disclosed. The hydrogels are characterized as being capable of shrinking and swelling in response to specific stimuli applied thereto. As the hydrogels shrink or swell, the lattice structure of the CCA embedded therein changes, thereby changing the wavelength of light diffracted by the CCA. Thus by monitoring the change in diffracted wavelength, the concentration of a stimulus is determined. The gels can be modified to sense numerous different stimuli. The sensor devices are specific in that they are modified to react with only one species or family of species. These sensors have various applications in areas including, for example, environmental and chemical systems, chemomechanical systems, sensor devices and medical diagnostic tools. Various methods for making and using these devices are also disclosed.
