The present invention relates to a novel probe set for an isothermal one-pot reaction, and uses thereof and, particularly, provides a method for easily, accurately, and quickly diagnosing molecules, in particular, infection diseases, in the field, the method having a form applicable in the field on the basis of a nucleic acid sequence by using a one-pot reaction composition under an isothermal condition. If a molecular diagnostic platform according to the present invention is used, a target sequence can be quickly and accurately detected. Also, elements (reaction buffer, enzyme) needed in a diagnostic process using the present invention are much more simple and convenient than in a conventional antibody-based diagnosis, and, thus, the diagnostic process can be performed by a non-skilled person, and the sensitivity and speed of diagnosis can be increased, as all reactions are unified at a constant temperature without expensive equipment used in general nucleic-acid-based molecular diagnostic technology, and an amplification process is performed automatically during a reaction process.

The invention provides compositions and methods allowing for rapid, accurate, robust, and low-cost diagnosis of infectious diseases via extraction-free, direct PCR techniques.

Methods of profiling the nucleic acid composition of single cells and tools for same. The methods can include isolating a single cell in a liquid droplet, lysing the single cell in the liquid droplet to release template nucleic acid from the cell, amplifying the template nucleic acid in the liquid droplet to generate amplified nucleic acid, and detecting the amplified nucleic acid in the liquid droplet. The methods can be useful for profiling expression patterns and/or detecting genetic characteristics such as single nucleotide polymorphisms. The tools include nucleic acid logic gates, including polymerase-dependent logic gates. The logic gates can perform logical operations such as YES, NOT, AND, OR, AND-NOT, NOT-AND, NOT-OR, EXCLUSIVE-OR, EXCLUSIVE-NOR, and IMPLY. The tools also include microfluidic systems for performing the methods.
