Research Interest: Dr Mei's research expertise is in
biofilms and biomaterials. His recent research activities are mainly focused on
the mechanism and prevention of bacterial adhesion and biofilm formation on
dental materials.
He
has measured the adhesion forces between living bacteria and orthodontic
materials using atomic force microscopy at a nano-level, and decoupled the
bacterial adhesion forces into specific and non-specific forces. In addition,
he has investigated measures for preventing biofilm formation using quaternary
ammonium compounds. He developed a novel contact-killing surface by
incorporating quaternary ammonium compounds into composite resin and studied
its efficacy of killing the adhered bacteria and its bio-safety for human
cells.
His
other interests include randomized controlled trials (RCT) and evidence-based
dentistry. He has investigated clinical methods for enhancing oral hygiene in
patients wearing fixed orthodontic appliances.
