Abstract: The present disclosure provides a method for trapping molecules with optical fiber tweezers based on phase transition and crystallization and a method for detecting a Raman spectrum of a persistent organic pollutant, belonging to the technical field of surface-enhanced Raman spectroscopy. Based on quite different solubilities of a substance to be detected in different solvents, dissolved phase small molecules to be detected are transformed into large size crystalline phase molecules through the physical process of phase transition and crystallization. Further, effective trapping of molecules to be detected that are not prone to bonding to noble metal nanoparticles in the vicinity of the noble metal nanoparticles can be achieved by combining the physical process of phase transition and crystallization with the physical trapping technique using optical fiber tweezers, so that the sensitivity of surface-enhanced Raman scattering (SERS) spectrum detection is significantly improved.

Abstract: A maximum pacing rate limiter for use in adaptive rate pacing in conjunction with a cardiac rhythm management system for a heart. The maximum pacing rate limiter may function to measure an interval, termed the ERT interval, between a paced ventricular evoked response and a T-wave. The maximum pacing rate limiter may further function to maintain the ERT interval at less than a certain percentage of the total cardiac cycle. In one disclosed embodiment, a maximum pacing rate limiter calculates an ERT rate based on the detected paced ventricular evoked response and the T-wave, and the pacing rate limiter module further communicates the minimum of the ERT rate and an adaptive-rate sensor indicated rate to a pacemaker.
