Publication 1: Liquid Crystalline Hydroxyapatite Nanorods Orchestrate Hierarchical Bone-Like Mineralization

Short Summary of the Paper: Researchers from University College London (UCL) developed liquid crystalline hydroxyapatite (HAp) nanorods that closely mimic the natural nanostructure of bone. These aligned nanorods guided stem cells to produce an organized extracellular matrix and promoted highly ordered calcium mineral deposition, leading to bone-like tissue formation. The study also identified the PI3K-Akt signalling pathway and the genes COL1A1 and COL4A6 as key regulators of this process, providing new insights into bone regeneration and biomimetic scaffold design.

  • Produced uniform PDMS thin films on glass coverslips.
  • Enabled controlled spin coating of hydroxyapatite nanorod suspensions, ensuring a reproducible and homogeneous coating.
  • Helped create highly aligned liquid crystalline hydroxyapatite surfaces, which were essential for studying cell alignment and mineralization.
  • Delivered precise coating thickness and repeatability, improving the reliability of the biological experiments and material characterization.

Key highlights:

  • Published in high-impact journal “small”.
  • Research conducted at University College London (UCL).
  • Navson NT 12000 Spin coater used for preparing uniform PDMS and hydroxyapatite coatings.
