How to unlock flexible mesoporous gold film sensors for a new generation of implantable medical devices?

With the continuous development of medical technology, implantable medical devices have become an important means to improve the quality of human life. However, the reliability and safety of implantable medical devices have been the focus of attention in the medical community. As one of the core components of implantable medical devices, IRF630 sensor needs to have the characteristics of high sensitivity, high precision, high stability and long life. As a new type of sensor material, flexible mesoporous gold film sensor has good biocompatibility, flexibility and high sensitivity, so it has become a research hotspot in the development of a new generation of implantable medical devices.

Ⅰ, The development of flexible mesoporous gold film sensors

Flexible mesoporous gold film sensor is a kind of sensor based on mesoporous materials. Mesoporous materials are porous materials composed of micron or nanometer pores, which have large specific surface area and good catalytic performance. Mesoporous materials have wide application prospects in sensor field because of their adjustable pore size and easy surface modification.

The main material of flexible mesoporous gold film sensor is mesoporous gold film, and its preparation methods include sol-gel method, electrochemical deposition method, thermal evaporation method, etc. Among them, sol-gel method is one of the most commonly used preparation methods. In this method, the metal precursor in the sol forms nanoparticles in the water phase of the gel, and then the gold film is formed by heat treatment or light treatment. The method of electrochemical deposition is to deposit metal ions on the electrode surface by electrolysis to form a gold film. The principle of thermal evaporation is to heat the metal material to the sublimation temperature, so that the metal evaporates and deposits on the substrate surface to form a thin film.

Flexible mesoporous gold film sensors have a wide range of applications, including environmental monitoring, food safety, medical diagnosis and other fields. Among them, implantable medical devices are one of the important application fields of flexible mesoporous gold film sensors.

Ⅱ, The application of flexible mesoporous gold film sensor in implantable medical devices

1. Cardiac pacemaker

A pacemaker is a commonly used implantable medical device used to treat arrhythmias in patients with heart disease. While traditional pacemakers require surgical incision into the chest for implantation, the flexible porous gold film sensor can be implanted through minimally invasive surgery, reducing surgical risks and patient pain. Flexible porous gold film sensors can measure the heart's electrical signals and transmit them to a pacemaker, which then stimulates the heart according to the signals. The flexible porous gold film sensor has high sensitivity and high precision, which can monitor the electrical signal of the heart in real time and improve the treatment effect of the pacemaker.

2. Eeg monitor

Electroencephalogram (EEG) monitor is an implantable medical device used to monitor electrical signals in the brain. It is often used to diagnose diseases such as epilepsy and stroke. Traditional EEG monitors require surgical incision of the skull for implantation, while flexible porous gold film sensors can be implanted through minimally invasive surgery, reducing the risk of surgery and patient pain. The flexible mesoporous gold film sensor can monitor the EEG signal in real time and transmit the signal to the monitor to realize the continuous monitoring of the EEG signal. The flexible mesoporous gold film sensor has high sensitivity and stability, which can accurately record EEG signals and improve the diagnostic accuracy of the monitor.

3. Blood sugar monitor

A glucose monitor is an implantable medical device used to monitor blood sugar levels and is often used to treat conditions such as diabetes. While traditional blood glucose monitors require blood collection by piercing the skin, the flexible mesoporous gold film sensor can be implanted into the subcutaneous tissue for blood glucose monitoring, reducing the patient's pain and the risk of infection. The flexible porous gold film sensor can monitor the blood glucose level in real time and transmit the data to the monitor to realize the continuous monitoring of the blood glucose level. The flexible porous gold film sensor has high sensitivity and high precision, which can accurately measure the blood glucose level and improve the therapeutic effect of the monitor.

Ⅲ, The development prospect of flexible mesoporous gold film sensor

Flexible mesoporous gold film sensor is a new kind of sensor material with broad application prospect. With the continuous development of implantable medical devices and people's attention to health, flexible mesoporous gold film sensors have a broad application prospect in the medical field. In the future, the flexible mesoporous gold film sensor will continue to develop, and its application in implantable medical devices will be more extensive. At the same time, flexible mesoporous gold film sensors will also be used in other fields, such as environmental monitoring, industrial production, etc., to make greater contributions to the sustainable development of human society.
