Drug delivery system for sustained delivery of bioactive agents

A method for producing parenchymal cell cellulose by using a high consistency alkali treatment and an optional refinement step, as well as an apparatus for its manufacture.

Method for producing parenchymal cell cellulose

Methods for manufacturing, re-activating and using compositions including fibrillated parenchymal cellulose and activator are provided. The activator has a low molecular weight and is used to facilitate reactivation.

Parenchymal cellulose composition

Method for preparing a membrane from fibril cellulose includes supplying fibril cellulose dispersion on a filter layer, draining liquid from a fibril cellulose dispersion by the effect of reduced pressure through the filter layer that is impermeable to fibrils of the fibril cellulose but permeable to the liquid to form a membrane sheet on the filter fabric, applying heat on the opposite side of the membrane sheet to the membrane sheet while continuing draining of the liquid through the filter layer by pressure difference over the filter layer, and removing the membrane sheet from the filter layer as a freestanding membrane.

Method for preparing a membrane from fibril cellulose and fibril, cellulose membrane

The invention relates to a method for producing paper, board or the like. The method comprises obtaining a thick stock comprising cellulose fibres, forming a fibrous web and drying of drying the fibrous web. A strength agent system, which comprises at least one synthetic or natural polymer, or their mixture, and microfibrillated parenchymal cellulose material originating from non-wood sources, is added to the thick stock. The invention relates also to paper or board produced by the method.

Separation methods based on electrophoresis or chromatography that use a stationary phase including fibril cellulose.

Use of stationary phase comprising fibril cellulose in separation methods

The present invention provides a method for determining carbonyl ratio and/or concentration of oxidized nanofibrillar cellulose in a sample. In accordance with the invention oxidized nanofibrillar cellulose comprised in the sample is enzymatically hydrolyzed into oxidized cellobioses which are specific markers to oxidized nanofibrillar cellulose. The cellobioses may be then analyzed and quantified to reveal the amount of oxidized nanofibrillar cellulose in the sample. A method for determining the concentration of oxidized nanofibrillar cellulose in a sample comprises steps of providing an analytical sample of material comprising oxidized nanofibrillar cellulose; hydrolyzing the analytical sample to breakdown products of oxidized nanofibrillar cellulose in presence of one or more enzymes; subjecting the breakdown products to a separation analysis to reveal the relative amounts of the breakdown products; and determining the concentration of oxidized nanofibrillar cellu-lose.
