This disclosure provides technology for ordering sequence information derived from one or more target polynucleotides. In one aspect, one or more tiers or levels of fragmentation and aliquoting are generated, after which sequence information is obtained from fragments in a final level or tier. Each fragment in such final tier is from a particular aliquot, which, in turn, is from a particular aliquot of a prior tier, and so on.

The present invention discloses a fluorescence lifetime temperature measurement method using dual-path signals. The method uses a temperature probe prepared from a rare earth ion dual-doped nanofluorescent material to detect temperature. The excited state energy of doped ion 1 in the nanofluorescent material is higher than that of doped ion 2.

A fitting curve of the fluorescence lifetime ratio of doped ion 1 to doped ion 2 versus temperature is used as a calibration curve for the temperature probe. The temperature measurement operating range of the probe is determined based on a theoretical temperature measurement sensitivity curve. The fitting formula corresponding to the calibration curve is used to reversely infer the detected temperature based on the measured fluorescence lifetime ratio. The present invention does not rely on the penetration depth of the probe into the object to be measured and can be used for temperature measurement on the surface of the material. It is also suitable for temperature monitoring in complex environments within the material. The rare earth ion doping system can be flexibly designed to select the fluorescence band corresponding to the acquisition signal.
