Embodiment 3

[0040] Human normal epidermal cells HaCaT were cultured in Dulbecco's Modified Eagle's Medium (DMEM) medium (containing 10% newborn bovine serum) at 37°C and 5% CO 2 Cultivate under conditions, and change the culture medium once every 1-2 days. When the cells grow to the logarithmic phase, the metal pattern substrate obtained in Example 1 and Example 2 and the polyethylene substrate before carboxylation are added for treatment. Place the cells in a 96-well plate with 0.25% trypsin at 37°C, 5% CO 2 Incubator cultivation. After 2 to 4 hours, each culture plate was added with the metal pattern substrate obtained in Example 1 and Example 2, the polyethylene substrate before carboxylation and the cells cultured in complete culture medium as the experimental group and the control group, without cells and cultured solution as a blank control, the culture plate was moved to 37 ℃, 5% CO 2 Incubator cultivation. After 24 hours, discard the culture medium, wash the plate twice with p...

Abstract

The invention relates to a carboxymethyl ruthenium compound and provides application of a beta-cyclodextrin and carboxymethyl ruthenium compound complex solution in the microcontact printing technology. Beta-cyclodextrin is dissolved in water to obtain a beta-cyclodextrin water solution with the concentration of 3-6 g / L, 0.8g of carboxymethyl ruthenium compound is added to each liter of beta-cyclodextrin water solution, then the frequency is adjusted to 20 kHz ultrasound for 30-60 min by an ultrasonic apparatus, and a PDMS seal is soaked with an obtained homodisperse beta-cyclodextrin and carboxymethyl ruthenium compound complex solution and a carboxylation substrate is covered with the seal for electroless plating. According to the beta-cyclodextrin and carboxymethyl ruthenium compound and the application thereof in the microcontact printing technology, a new thought is provided for microcontact printing ink in preparing metal patterns in the surface of a polymer substrate frequently used in the electron industry and the microcontact printing industry.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of a beta-cyclodextrin and carboxymethyl ruthenium compound as a composite green ink in micro-contact printing technology. Background technique [0002] Surface micro-structuring technology is gradually showing important application value, especially micro-contact printing technology, which can be micro-patterned on a small scale, which is of great significance in many fields, especially in the field of modern electronic technology. At present, there are few microcontact printing inks to choose from, and the materials that can be printed on the surface are limited. A large number of materials cannot be prepared with surface patterns by microcontact printing. Therefore, it is of great significance to develop new and stable inks. [0003] The applicant discloses eight (octyloxy)-phthalocyanine zinc in the authorized patent (CN102516841B) as in...
