Abstract:

The invention relates to biological arrays, biological microarrays, and methods of using the arrrays and microarrays to detect the amount and/or presence of a biological molecule in a biological sample. Biological arrays of the invention comprise a solidified, sectionable matrix comprising a plurality of wells disposed therein and one or more biological samples disposed within the plurality of wells, which biological arrays optionally comprise an internal standard preparation and/or an orientation marker. Sections or slices of the biological arrays are mounted on a planar substrate surface to form cellular microarrays of the invention. In alternative cellular microarrays of the invention, the matrix material is a temperature-sensitive material removable from the microarray leaving cellular biological material on the substrate surface.

Abstract:

A method of preparing a low-density material and precursor for forming a low-density material is provided. An aqueous mixture of inorganic primary component and a blowing agent is formed, the mixture is dried and optionally ground to form an expandable precursor. Such a precursor is then fired with activation of the blowing agent being controlled such that it is activated within a predetermined optimal temperature range. Control of the blowing agent can be accomplished via a variety of means including appropriate distribution throughout the precursor, addition of a control agent into the precursor, or modification of the firing conditions such as oxygen deficient or fuel rich environment, plasma heating etc.
