The researchers mixed hydrochloric acid with polylactic acid and calcium carbonate particles, dispersed calcium carbonate particles with a diameter of several nanometers into polylactic acid, and reacted with hydrochloric acid to produce carbon dioxide. Finally, spherical hollow composite particles were obtained. Many fine pores can be observed on the surface of newly synthesized composite particles, and bone cells can easily enter the particles through the pores. If a special chemical reaction takes place in this composite particle, part of the polylactic acid will be transiently fluidized. After it is re-hardened, the composite particles will bind together and the bone cells will easily enter the gap between the particles, promoting the skeleton. form.
New hollow composite particles promote bone growth
The Graduate School of Nagoya Institute of Technology in Japan invented a kind of hollow composite particles synthesized from biodegradable plastics and calcium compounds. It can be injected into living organisms or implanted into artificial bone to promote the formation of bones.
