摘要： A convective polymerase chain reaction apparatus includes a tube, a temperature control unit, at least one light source and a sensor. The tube includes a cavity used to contain a reaction solution. The reaction solution has a liquid level measured from a bottom of the cavity to a top surface of the reaction solution. The temperature control unit is disposed adjacent to the tube for controlling the temperature of the reaction solution. The at least one light source provides a light beam passing through an incident portion of the tube to excite the reaction solution emitting a fluorescent light. The incident portion is located at a height greater than ½ of a liquid level. The sensor is adjacent to the tube for detecting the excited fluorescence. The light beam has an incident direction forming a non-straight angle with a long axis of the tube.

摘要： Exothermic and/or endothermic chemical reactions in combination with phase change materials can produce output temperature(s) within strict tolerances without requiring expensive and complicated external equipment to generate and maintain an output temperature. Similarly, an exothermic phase change material, which generates heat as a consequence of crystallizing a supercooled liquid, can generate heat at a constant temperature, without requiring expensive and complicated external equipment, as a consequence of the liquid form of the exothermic phase change material being in equilibrium with the solid form of the exothermic phase change material. Numerous biological and chemical processes and/or diagnostic devices require a constant temperature or temperatures for set periods of time. An example completely non-instrumented diagnostic platform based on nucleic acid amplification is described, which is particularly suited for use in developing countries that may not have access to expensive and complicated external equipment.
