摘要： The present invention relates to a method of detecting single nucleotide polymorphisms by providing a target nucleic acid molecule, an oligonucleotide primer complementary to a portion of the target nucleic acid molecule, a nucleic acid polymerizing enzyme, and a plurality of types of nucleotide analogs. The target nucleic molecule, the oligonucleotide primer, the nucleic acid polymerizing enzyme, and the nucleotide analogs, each type being present in a first amount, are blended to form an extension solution where the oligonucleotide primer is hybridized to the target nucleic acid molecule to form a primed target nucleic acid molecule and the nucleic acid polymerizing enzyme is positioned to add nucleotide analogs to the primed target nucleic acid molecule at an active site. The oligonucleotide primer in the extension solution is extended by using the nucleic acid polymerizing enzyme to add a nucleotide analog to the oligonucleotide primer at the active site. This forms an extended oligonucleotide primer, wherein the nucleotide analog being added is complementary to the nucleotide of the target nucleic acid molecule at the active site. The amounts of each type of the nucleotide analogs in the extension solution after the extending step are then determined where each type is present in a second amount. The first and second amounts of each type of the nucleotide analog are compared. The type of nucleotide analog where the first and second amounts differ as the nucleotide added to the oligonucleotide primer at the active site is then identified. The steps of extending, determining the amounts of each type of the nucleotide analog, comparing the first and second amounts of the nucleotide analog, and said identifying the type of nucleotide analog added may be repeated, either after repeating the blending with the extended oligonucleotide primer or after determining the amounts of each type of dideoxynucleotide or dideoxynucleotide analog remaining in the extension solution as the new first amount. As a result, the nucleotide at the active site of the target nucleic acid molecule is determined. Also disclosed is an apparatus and composition for carrying out this method.

The electrospray device includes a substrate defining a channel between an entrance orifice on an injection surface and an exit orifice on an ejection surface, a nozzle defined by a portion recessed from the ejection surface surrounding the exit orifice, and an electric field generating source for application of an electric potential to the substrate to optimize and generate an electrospray. A method and system are disclosed to generate multiple electrospray plumes from a single fluid stream that provides an ion intensity as measured by a mass spectrometer that is approximately proportional to the number of electrospray plumes formed for analytes contained within the fluid. A plurality of electrospray nozzle devices can be used in the form of an array of miniaturized nozzles for the purpose of generating multiple electrospray plumes from multiple nozzles for the same fluid stream. This invention dramatically increases the sensitivity of microchip electrospray devices compared to prior disclosed systems and methods.

摘要： A method for fabricating a nozzle of microchip-based electrospray device is disclosed. The method includes using a primary mask to accurately define the nozzle feature including the annulus and the through hole of the electrospray device. A secondary masking step is conducted to pattern the through channel (typical the photoresist would serve as the secondary mask), followed by the defining and etching of the primary mask containing the full nozzle feature. The secondary mask serves to selectively mask given areas of the primary mask for subsequent etching. The through hole feature of the secondary mask aligns over the already patterned primary mask through channel, except that the secondary mask contains a slightly larger through channel diameter. This serves to mask off the annulus, but allowing the silicon through channel to be exposed for etching.
摘要翻译：公开了一种用于制造基于微芯片的电喷雾装置的喷嘴的方法。该方法包括使用主掩模来精确地限定包括电喷雾装置的环形区域和通孔的喷嘴特征。进行二次掩模步骤以对穿通通道进行图案化（典型地，光致抗蚀剂将用作辅助掩模），然后限定和蚀刻含有全喷嘴特征的主掩模。辅助掩模用于选择性地掩蔽初级掩模的给定区域用于随后的蚀刻。辅助掩模的通孔特征通过通道对准已经图案化的初级掩模，不同之处在于次要掩模包含稍大的通道直径。这用于掩盖环形，但允许硅通过沟道暴露以进行蚀刻。
