Stable Zeolite/Cellulose Composite Materials And Method Of Preparation, Gustavo F. Larsen
Department of Chemical and Biomolecular Engineering: Patents
Stable cellulosic fiber material for use in forming zeolite/cellulose composites is prepared by suspending loose cellulose fibers in an aqueous solution of sodium hydroxide, potassium hydroxide or sodium silicate, stirring the resulting suspension until it reaches a macroscopically homogenous appearance, heating the resulting mixture at a temperature of 323-423 K until only dry solids remain, contacting the resulting mixture with excess distilled water to remove physically adsorbed or trapped sodium hydroxide, potassium hydroxide or sodium silicate from the fibers, and heating the resulting fiber material at 323-423 K to dry the fiber material. Stable zeolite/cellulose composite material characterized in that …

A method detects binding of molecules, advantageously without tagging molecules in the sample. A sensor is used in which is included a single stranded nucleic acid sequence and a photoluminescent material in respective layers. After the sensor is exposed to a biological sample for sufficient time for its single stranded nucleic acid sequence to bind to a material of interest, photoluminescence from the sensor can be measured. An apparatus for tagging-free detection of binding of molecules also is provided. Methods of making tagging-free sensors are provided. Also, tagging-free methods to detect binding of antigens and related devices are disclosed.
