Abstract
A method of forming a biological sensor on a predetermined area of a substrate. The method includes dispensing a plurality of layers on the predetermined area of the substrate. Each of the plurality of layers is formed of a substantially different fluid having a substantially different function. The dispensing of the layers is accomplished by a drop generating member.

A method of forming a biological sensor on a predetermined area of a substrate, the method comprising dispensing a plurality of layers on the predetermined area of the substrate, each of the plurality of layers formed of a substantially different fluid having a substantially different function, the dispensing being accomplished by a drop generating member.
A diagnostic device, comprising:
- a substrate;
- and
- a sensor established on a predetermined area of the substrate, the sensor including a plurality of layers, wherein each of the plurality of layers is formed of a substantially different fluid having a substantially different function, and wherein the sensor is established by a drop generating member.
A system for at least one of diagnosing and monitoring at least two different parameters, the system comprising:
- a substrate having at least two channels defined thereon;
- a first sensor established in one of the at least two channels;
- and
- a second sensor established in the other of the at least two channels, each of the sensors including at least one layer, wherein the at least one layer is formed of a fluid having a predetermined function, each of the sensors is established by a drop generating member, and the first sensor is adapted to detect one of the at least two different parameters, and the second sensor is adapted to detect the other of the at least two different parameters.
A method of testing a sample for at least two different parameters, the method comprising:
- introducing a sample into a microfluidic device, the device having at least two conduits, each of the at least two conduits having a sensor positioned therein, each of the sensors including at least one layer formed of a fluid having a predetermined function, and each of the sensors is established by a drop generating member;
- dividing the sample such that a first portion is introduced into one of the at least two conduits, and a second portion is introduced into the other of the at least two conduits;
- and
- exposing the first portion of the sample to the sensor positioned in one of the at least two conduits and the second portion of the sample to the sensor positioned in the other of the at least two conduits;
- wherein one of the sensors is adapted to detect one of the at least two different parameters, and the other of the sensors is adapted to detect the other of the at least two different parameters.
A microfluidic system, comprising:
- a housing defining a fluid passage having at least two conduits;
- a first biological sensor positioned in one of the at least two conduits;
- and
- a second biological sensor positioned in the other of the at least two conduits, the first and second biological sensors including a plurality of layers, wherein each of the plurality of layers is formed of a substantially different fluid having a substantially different function, and each of the sensors is established by a drop generating member;
- wherein the first biological sensor is adapted to detect a first parameter, and the second biological sensor is adapted to detect a second parameter different from the first parameter.
