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 terephthalate 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 terephthalate substrate before carboxylation, and the cells cultured in complete culture medium as the experimental group and the control group. Group, without cells and culture medium as a blank control, the culture plate was moved to 37 ℃, 5% CO 2 Incubator cultivation. After 24 hours, discard the culture me...

Abstract

The invention relates to a rare earth Tb complex and further provides application of a compound solution of the rare earth Tb complex and gamma-cyclodextrin in the microcontact printing technique. The application comprises the steps of dissolving gamma-cyclodextrin into water, so as to obtain a 3g / L-6g / L gamma-cyclodextrin water solution, adding 0.8g of rare earth Tb complex into each liter of the gamma-cyclodextrin water solution, regulating the frequency at 20kHz, carrying out ultrasonic treatment for30-60 minutes by virtue of an ultrasonic instrument, so as to obtain the uniformly-dispersed compound solution of gamma-cyclodextrin and the rare earth Tb complex, soaking a PDMS stamp into the compound solution, covering a carboxylation substrate with the PDMS stamp, and carrying out chemical plating. According to the application, a metal pattern is prepared on polymer substrates frequently used in the electron industry by virtue of microcontact printing ink, and a new thought is provided for 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 gamma-cyclodextrin and rare earth Tb 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 polye...
