An articular cartilage bioreactor is a device for culturing and maintaining human articular chondrocytes and can be used to study cartilage biology and explore treatments. It generally consists of multiple layers of components, including a cell culture chamber, fluid circulation system, pressure sensor, and temperature controller. Its basic principle is to culture articular cartilage tissue on a gas-permeable, porous, elastic artificial matrix and promote its growth and development through simulated physiological stimuli such as joint movement, pressure, and fluid shear. Main components include a culture chamber, artificial matrix, pressure sensor, fluid pump, and control system. Maintenance steps: 1. Regular cleaning: regularly clean the reactor's interior and exterior...

Cell adhesion is a key interaction between cells and their surrounding environment and is essential to biological functions such as migration, proliferation, and signal transduction. Measuring and understanding adhesion forces is therefore important to studying cell behavior and physiological processes. Recent advances in cell adhesion force measuring instruments have provided powerful tools for this field. Such instruments are generally based on microfluidic mechanics and measure adhesion between cells and a substrate by applying controlled shear force or pressure. Common methods include traction force microscopy, magnetic bead traction, and microfluidic chips. Combined with image processing and mechanical analysis, these technologies monitor and quantitatively assess cell–substrate adhesion in real time. A cell adhesion force measuring instrument generally consists of the following comp...

The cornea is the transparent front surface of the eye and is essential to maintaining good visual function. Corneal transparency is an important indicator for assessing health and conditions including inflammation, edema, and lesions. Traditional assessments rely mainly on subjective observation and clinical experience and lack objectivity and quantitative measurement. A quantitative corneal transparency meter uses optical principles and image-processing technology to assess transparency by measuring light intensity transmitted through the cornea. It directs a standardized light source at the cornea and records transmitted-light intensity. Analysis and processing produce a quantitative transparency value. When using a quantitative corneal transparency meter, observe the following prec...
