Abstract
Hydrogel-based or aerogel-based devices and methods for pretreatment of a sample. The devices and method may include an aerogel-based device for pretreating a sample comprising at least one aerogel; a hydrogel-based device for pretreating a sample comprising at least one hydrogel; or a combination aerogel-based and hydrogel-based device for pretreating a sample comprising at least one aerogel in fluid communication with at least one hydrogel.
Claims24
A device for concentrating an analyte of interest, comprising:
- an aerogel, said aerogel including (i) a filter layer, and (ii) a fluid storage layer.
A device for concentrating an analyte of interest, comprising:
- a hydrogel, said hydrogel including (i) a filter layer, (ii) a fluid storage layer, and (iii) one or more sensing modalities present in a polymer or synthetic matrix of the fluid storage layer.
A device for pretreating a sample, comprising:
- at least one aerogel, said at least one aerogel including (i) a filter layer, and (ii) a fluid storage layer.
A method of making a device for concentrating an analyte of interest, the method comprising:
- positioning a first hydrogel and a second hydrogel adjacent to one another, wherein the density of the first hydrogel is different from the density of the second hydrogel;
- and
- removing water from the first hydrogel and the second hydrogel to form an aerogel, said aerogel including a first layer and a second layer.
A method of pretreating a sample, the method comprising:
- contacting a fluid sample with an aerogel or a hydrogel, wherein said aerogel or said hydrogel includes (i) a filter layer, and (ii) a fluid storage layer.
