Chitosan double-network quick response-type injectable hydrogel and preparation method thereof

The invention relates to chitosan double-network quick response-type injectable hydrogel and a preparation method thereof. The injectable hydrogel is prepared from chitosan or derivatives of the chitosan and sodium glycerophosphate serving as raw materials, and dialdehyde compounds or diepoxy compounds serving as crosslinking agents, wherein the mass ratio of the chitosan to the sodium glycerophosphate is 1:(0.5-10); the mass ratio of the crosslinking agents to the chitosan is (0.01-1):1. The method comprises the following steps: evenly mixing a hydrochloric acid aqueous solution of the chitosan with a sodium glycerophosphate solution in the environment at -1 to 5 DEG C, so as to obtain a solution of which the pH is 7-7.2, and evenly mixing the solution with a crosslinking solution at 35-37 DEG C. Transformation from a sol state to a gel state can be quickly finished under a specific condition, the process is irreversible, and the transition time is controllable. The chitosan double-network quick response-type injectable hydrogel has the advantages of simple reaction condition, short response time, good thermal stability of gel, high mechanical strength, good biocompatibility and the like. The chitosan double-network quick response-type injectable hydrogel is applied to the fields such as tissue filling and repairing, biological scaffolds, scar resistance and anti-adhesion, biogel, and quickly molding or three-dimensional printing materials and the like.

Fast aging response type Al-Mg-Si-Cu-Zn series alloy and preparation method thereof

InactiveCN103789583AHigh strengthFast time-sensitive response characteristicsRoom temperatureResponse type
The invention provides a novel Al-Mg-Si-Cu-Zn series alloy with fast aging response and a preparation method thereof. According to the invention, the novel Al-Mg-Si-Cu-Zn series alloy shows excellent fast aging response characteristic in an aging process by sufficiently utilizing the synergetic precipitation effect and synergetic strengthening effect of the main strengthening phases Mg2Si, MgZn2 and transitional phase of an Al-Mg-Si series alloy and an Al-Zn-Mg-Cu series alloy; the natural aging deterioration effect of a common Al-Mg-Si-Cu series alloy is certainly inhibited due to the simultaneous addition of Mg, Si, Cu and Zn elements and the addition of element Zn especially, the novel Al-Mg-Si-Cu-Zn series alloy has low strength and high room temperature stability after being subjected to preaging treatment at a certain temperature, which is favorable to the subsequent stamping forming of an alloy plate; a preaging-state alloy is greatly enhanced in strength after being subjected to high-temperature aging treatment and achieves the highest strength increment approaching to 150 MPa far higher than that of the traditional AA6016 and AA6111 alloys through short-term artificial aging at 185 DEG C for 20 minutes; the fast aging response characteristic is not only suitable for the preparation of an automobile outside plate, but also suitable for the related field with a special requirement on the aging precipitation speed of the alloy plate.

Double-ion response type SERS (Surface Enhanced Raman Scattering) probe and preparation method thereof

InactiveCN103616367AEasy to separatePlay a role in purifying the environmentRaman scatteringNanotechnologyResponse typeSilicon dioxide
The invention discloses a double-ion response type SERS (Surface Enhanced Raman Scattering) probe and a preparation method thereof. The probe comprises two nano particles with independent core-shell structures, wherein a carrier nano particle comprises four layers of core-shell structures; the four layers of core-shell structures are as follows: the innermost layer is made of Fe3O4 magnetic nano balls, a layer of silicon dioxide is coated outside the innermost layer, the second-outer layer is a gold foil shell layer, and the outermost layer is an oligonucleotide coating layer; an object nano particle comprises two layers of core-shell structure; the two layers of core-shell structure are as follows: the inner core is made of Raman molecule marked gold nano-balls, and a shell is an oligonucleotide coating layer. Due to the adoption of a specific base sequence in the oligonucleotide coating layer, the identify and SERS trace detection on two metal ions, namely silver/mercury, in an environment solution can be performed at the same time; furthermore, under the action of an external magnetic field, the probe and the obtained silver/mercury ions can be rapidly separated from an initial environment solution system, and therefore, the function of purifying the environment is realized.
