The present disclosure provides methods, systems, and apparatuses for collecting and/or amplifying nucleic acids. In general, provided methods, systems, and apparatuses involve contacting a sample including a nucleic acid with a nucleic acid amplification reagent without purification of nucleic acids from the sample.
The speed of a nucleic acid amplification reaction, such as the Polymerase Chain Reaction (PCR), can be increased by setting the temperature of heat sources above and below the desired denaturation, annealing, and extension temperatures. The reaction mixture is only contacted with the heat sources long enough for the desired temperatures to be reached. A non-uniform temperature gradient is created from top to bottom, in the liquid, inside the reaction vessels.

SYSTEM FOR RAPID NUCLEIC ACID AMPLIFICATION AND DETECTION
A system is provided for carrying out rapid nucleic acid amplification or other biological reactions requiring thermal cycling. The system of this invention incorporates at least two heating blocks, each having a groove for receiving a reaction vessel such that only a portion of the outer surface of the walls of the vessel are in direct contact with the heating block. The remaining portion of the outer surface of the walls of the reaction vessel remains exposed to ambient conditions. The reaction vessel comes into contact with only one heating block at a time either by movement of the vessel between the heating blocks or by movement of the heating blocks in relation to the vessel. The system of this invention provides rapid temperature cycling without the need for extended ramping times generally associated with single block designs, which include a single temperature block that is forced to heat and cool. Heating and cooling of the reaction using the system of the present invention is accomplished by the reaction vessel and heating blocks coming into thermal contact and reaching thermal equilibrium. The entire vessel need not be surrounded by the heating block, with at least one side of the vessel partially open to ambient conditions. As a result of the configuration of this system it is readily combined with detection systems, for example, fluorescence detection systems.
