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 gold complex and also provides an application of a gold complex and alpha-cyclodextrin composite solution in the microcontact printing technology. The application method comprises the following steps: dissolving alpha-cyclodextrin with water to obtain an 3-6g / L alpha-cyclodextrin water solution, adding 0.8g of gold complex to each liter of alpha-cyclodextrin water solution, then regulating the frequency to 20kHz by using an ultrasonic apparatus and carrying out ultrasonic treatment for 30-60 minutes, thus obtaining a uniformly dispersed alpha-cyclodextrin and gold complex composite solution, soaking a PDMS seal in the alpha-cyclodextrin and gold complex composite solution, putting the PDMS seal on a carboxylated substrate and carrying out chemical plating. A new idea is provided for the microcontact printing industry by using the alpha-cyclodextrin and gold complex composite solution as the microcontact printing ink to prepare metal patterns on surfaces of polymer substrates commonly used in the electronics industry.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of an alpha-cyclodextrin and gold complex 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 ink in polyethylene ...
