Methods and related apparatuses for sorbent recharging are provided. The methods and related apparatuses for recharging can recharge a specific rechargeable layer of a sorbent material such as zirconium phosphate in a sorbent cartridge. The methods and apparatuses include passing solutions containing combinations of acids, bases and salts through a module containing a rechargeable sorbent material such as zirconium phosphate in order to replace ions bound to the zirconium phosphate with hydrogen and sodium ions. The method allows for a customizable zirconium phosphate, with control over the ratios of sodium to hydrogen on the recharged zirconium phosphate.

Embodiments of the invention provide analyte sensors having optimized permselective membranes and methods for making and using such sensors. Embodiments of the invention also provide analyte sensors such as those having porous matrices coated with an analyte sensing composition and methods for making and using such sensors. Illustrative embodiments include electrochemical glucose sensors having glucose oxidase coatings.

Biosensors and methods for making and using them

A long term analyte sensor for measuring at least one analyte in the body of a user and which includes a housing, a plurality of analyte contacting sensor elements and at least one structure for relaying information away from the sensor. This plurality of analyte contacting sensor elements are typically disposed in an array. The analyte sensor further includes at least one sensor protection membrane that is controllable in a manner such that sensor elements may be activated (e.g. exposed to the external environment) at different times so as to extend the useful life of the sensor. In illustrative analyte sensors, the analyte is glucose.
