DNA duplexes are ideal crosslinkers for building such gels because of their excellent sequence addressability and flexible tunability in bond energy. However, the mechanical responses of most DNA gels are complicated and unpredictable. The melting curve analysis of the DNA gels reveals the good correspondence between the thermodynamic potentials of the DNA crosslinkers and the presimulated values by DNA calculators. Stress-relaxation tests and dissociation kinetics measurements show that the macroscopic relaxation time of the DNA gels is approximately equal to the lifetime of the DNA crosslinkers over 4 orders of magnitude from 0.1-2000 s. Furthermore, a series of durability tests find the DNA gels are hysteresis-less and self-healable after the applications of repeated temperature and mechanical stimuli.

Selective separation and sensitive detection of dissolved silicon and boron (DSi and DB) in aqueous solution was achieved by connecting an electrodialytic ion isolation device (EID), an ion-exclusion chromatography (IEC) column, and a corona charged aerosol detector (CCAD) in sequence. They were separated by IEC using pure water eluent. Detection of DSi and DB by the CCAD was effective for much greater sensitivity than by conductimetric detection. The EID removed salt from the sample prior to the IEC-CCAD. The combination of EID, IEC and CCAD successfully separated and determined DSi and DB in artificial seawater and hot-spring water samples by eluting pure water.
