An articular cartilage bioreactor is a device for culturing and maintaining human articular-cartilage cells and can be used to investigate cartilage biology and potential treatments. The reactor generally comprises multiple components, including a cell-culture chamber, fluid-circulation system, pressure sensors and temperature controller. For an experiment, human articular-cartilage cells are first collected and placed in the culture chamber. Nutrient medium is then introduced into the circulation system; pressure is adjusted with the sensors and temperature with the controller to provide an optimal growth environment. As a medical device for treating articular-cartilage defects, it offers the following advantages: 1. Customization: it can be tailored to the patient’s individual...

A cell adhesion force measurement instrument is used to study interactions between cells and biological or nonbiological substrates. It can reproduce the forces experienced by cells in different environments, helping researchers better understand cell function and physiological processes. The instrument uses miniature force and displacement sensors to measure cell–substrate interactions. Researchers culture cells on a substrate, apply different forces with a micromanipulator, and calculate adhesion force from the resulting minute displacement and force signals. Procedure: 1. Preparation before the experiment: prepare cell-culture medium, sterile centrifuge tubes, a centrifuge, culture dishes, a microscope, cell suspension and other materials. 2. ...

A bioreactor is equipment for controlling biological processes and carrying out biochemical synthesis. It supports production in pharmaceuticals, medicine and biotechnology and can also play an important role in environmental protection. Bioreactor operation involves three balances: biomass, energy and mass transfer. Biomass balance describes microorganisms producing new cellular material through metabolism while consuming nutrients inside the reactor. Energy balance describes microorganisms obtaining energy from nutrients for metabolic activity and releasing heat to their surroundings. Mass-transfer balance covers the movement of matter and energy in the reactor, including transport among gases, solutions and microorganisms. Depending on the operating mode and...
