With the continued development of thermoresponsive colloidal hydrogel particles, a number of groups have begun to exploit their properties to create dynamic materials self-assembled from those components. The fundamental details of how those building blocks are assembled, the component functionality, and the geometry or length-scales present in the assemblies contribute to the behavior of the resultant material. In this tutorial review, we examine recent progress in the assembly of responsive hydrogel colloids in two and three dimensions, highlighting their potential applications, especially in the domain of biotechnology.

The tunability of the lattice spacing of hydrogel colloidal crystals has been achieved by simply varying the water content of the microgel pellet before annealing and crystallization. The manipulation of the lattice constant of the crystals and therefore of the wavelength of the resultant Bragg peak, i.e., the color of the crystal, leads to a myriad of photonic applications.

Raman microscopy also appeared (12). The latter had chapters on basic aspects of Raman microscopy, as well as chapters on applications in materials science, in earth, planetary, and environmental sciences, in biology, in medicine, and in forensic science. The proceedings of a conference on the spectroscopy of biological molecules was published, with the
