    摘要: Sample preparation can be a tedious and time consuming task. For example, MALDI imaging of tissue samples can require the tedious process of hand or robotically spotting solutions containing chemical species referred to as “matrix” onto a tissue sample prior its mass spectral analysis. Provided is a process for preparing a sample comprising immersing a solid support that has a surface comprising a first part that is more hydrophilic than a second part into a target compound solution, wherein the target compound is deposited primarily onto the more hydrophilic part; and/or applying and evaporating the target compound solution onto the substrate to produce the pre-coated substrate. A tissue or other sample may then be placed on the substrate for analysis.

    摘要: Method and apparatus for controlling acoustic treatment of a sample including a liquid. A processing volume in which the sample is acoustically treated may be controlled, e.g., by positioning a suitable element so as to reduce and/or eliminate a headspace size at a sample/gas interface. An interaction between the acoustic energy and the sample may be controlled, e.g., by using a headspace control element positioned at least partially in the sample that helps to reduce splashing or other sample ejection that would otherwise occur.

    摘要: The present invention relates to a formulations and methods for coupling a reactant (or probe precursor) to a functionalized surface for purposes of forming an arrayed sensor. This method includes the steps of: providing a surface having a reactive functional group; and introducing onto the surface, at a plurality of discrete locations, two or more compositions of the invention, which include a different reactant (probe precursor) and a non-nucleophilic additive, wherein such introduction is carried out under conditions effective to allow for covalent binding of the reactant to the surface via the reactive functional group. This results in a probe-functionalized array that substantially overcomes the problem of surface morphological anomalies on the array surface. Use of the resulting arrays in various detection systems is also encompassed.
