摘要: The present disclosure relates to polymers which contain a hydrophobic and hydrophilic segment which is sensitive to pH. In some aspects, the polymers form a micelle which is sensitive to pH and results in a change in fluorescence based upon the particular pH. In some aspects, the disclosure also provides methods of using the polymers for the imaging of cellular or extracellular environment or delivering a drug.

摘要: According to one or more embodiments, cationic polymers may be produced which include one or more monomers containing cations. Such cationic polymers may be utilized as structure directing agents to for mesoporous zeolites. The mesoporous zeolites may include micropores as well as mesopores, and may have a surface area of greater than 350 m2/g and a pore volume of greater than 0.3 cm3/g. Also described are core/shell zeolites, where at least the shell portion includes a mesoporous zeolite material.

摘要: The present invention pertains to a means and method for, from a mixture (cell culture) of cells, a medium component, and a useful substance, recovering the first two using a single process. Specifically, the present invention pertains to a polypeptide modified with a stimulus-responsive polymer, characterized in that the stimulus-responsive polymer responds to a stimulus to induce a change in the physical properties of the modified polypeptide overall, and the change is reversible or pseudo-reversible.
