Printed circuit boards and breadboard devices have contact pads and magnetic component connectors where connection between the contact pads and the magnetic component connectors are made by magnetic force. Either the contact pad or the magnetic component connector will be magnetic and the other will be made of a material to which a magnet will be attracted. For example, printed circuit boards, which usually have copper traces, include contact pads made of a material to which a magnet will be attracted. Circuit components are connected to magnetic component connectors having magnetic legs which then connect the components to the contact pads of the circuit board or breadboard device. This makes the connection of components to a printed circuit board or breadboard device fast and easy and provides for easy removal and replacement of components. Magnetic component connectors can also be configured to connect magnetically to one another.

Magnetic component connector, circuit boards for use therewith, and kits for building and designing circuits

Hydrogels containing catalase co-immobilized with an analyte-sensitive enzyme such as glucose oxidase are disclosed. The hydrogels may be pH-sensitive, and preferably are thin and lightly crosslinked. The catalase is present in concentrations ranging generally from 100 units/ml to about 1000 units/ml. These hydrogels have much faster swelling response times as compared to hydrogels without catalase, and are useful in biosensors and analyte-responsive drug delivery devices. The hydrogels also have an increased useful life, due to protection of the immobilize analyte-sensitive enzyme from degradation by hydrogen peroxide.

An implantable biosensor for detecting an analyte in vivo in body fluids comprises an analyte-sensitive hydrogel filament chemically configured to vary its displacement volume according to changes in concentration of an analyte, such as glucose, in a patient's body fluid. A photometric displacement transducer placed inside the biosensor is configured to quantifiably detect changes in the displacement volume of the hydrogel filament, such as by detecting the light intensity on a photoreceptor arranged to receive light of varying intensity depending upon the displacement of the hydrogel filament. A battery powered telemeter operably engaged to the photometric displacement transducer sends a radio data signal representing glucose concentration level to a receiver containing an alarm system. The alarm system can automatically notify a person that the analyte level is outside desired predetermined parameters, and/or to automatically inject an agent to counteract the adverse analyte levels.

Photometric glucose measurement system using glucose-sensitive hydrogel

An implantable chip biosensor for detecting an analyte in vivo in body fluids comprises an analyte-sensitive hydrogel slab chemically configured to vary its displacement volume according to changes in concentration of an analyte, such as glucose, in a patient's body fluid, the slab being disposed in a groove in a support block. The biosensor chip is 'read' by an external scanner configured to quantifiably detect changes in the displacement volume of the hydrogel slab. The support block is made of rigid or semi-rigid support material to restrain expansion of the hydrogel in all but one dimension, and the groove has one or more openings covered with a semipermeable membrane to allow contact between the patient's body fluid and the hydrogel. The scanning means may be any type of imaging devices such as an ultrasound scanner, a magnetic resonance imager (MRI), or a computerized tomographic scanner (CT) capable of resolving changes in the slab's dimensions.

A biosensor ( ) has a hydrogel ( ) in a rigid and preferably biocompatible enclosure ( ). The hydrogel ( ) includes an immobilized analyte binding molecule (ABM) and an immobilized analyte. The immobilized analyte competitively binds with free analyte to the ABM, thus changing the number of crosslinks in the hydrogel ( ), which changes hydrogel swelling tendency (and thus the osmotic pressure) in its confined space in proportion to the concentration of free analyte concentration. By measuring the change in hydrogel pressure with a pressure transducer ( ), the biosensor ( ) is able to accurately measure the concentration of the free analyte molecule without the problem of oxygen limitations and interference encountered by prior art biosensors. A battery ( ) powered telemeter ( ) operably engaged to the pressure transducer ( ) sends a radio data signal to a receiver ( ) containing an alarm system operably attached to a computer ( ). Furthermore, an alarm system utilizes such a sensor to automatically notify a person that the analyte level is outside desired predetermined parameters, and/or to automatically inject an agent to counteract the adverse analyte levels.

A biosensor ( ) has a hydrogel ( ) in a rigid and referably biocompatible enclosure ( ). The hydrogel ( ) includes an immobilized glucose-binding molecule such as concanavalin A (Con A) and an immobilized hexose saccharide such as a-D-mannopyranoside. The immobilized hexose saccharide competitively binds with free glucose to the glucose-binding molecules, thus changing the number of crosslinks in the hydrogel ( ), which changes hydrogel swelling tendency and the pressure of the hydrogel in its confined space in proportion to the concentration of free glucose. By measuring the change in hydrogel pressure with a pressure transducer ( ), the biosensor ( ) is able to accurately measure the concentration of the tree glucose molecule without the problem of oxygen limitations and interference encountered by prior art biosensors. A battery ( ) powered telemeter ( ) operably engaged to the pressure transducer ( ) sends a radio data signal to a receiver ( ) containing an alarm system operably attached to a computer ( ). Furthermore, an alarm system utilizes such a sensor to automatically notify a person that the blood glucose level is outside a predetermined parameter, and/or to automatically inject an agent such as glucose or glycogen which will raise blood glucose levels.
