We work at the interface of biology and materials science and aiming to address the challenges of sustainable synthesis of nanomaterials, eradication of biofilm formation, novel healthcare materials development and treatment of wound infection. The current research focus is emphasized on designing and synthesis of bioinspired nanomaterials for healthcare and biomedical applications and it is divided into five research directions:
Fabrication of nanomaterials by bioinspired and biomimetic approach: About 500 million years ago organisms started growing inorganic materials like calcium carbonate, silica, bone and glass. The synthesis process occurs through a biologically guided process known as biomineralization. Inspiring from this natural occurring process, our research effort is focused on the development of novel strategies for the controlled nanomaterial synthesis using living organisms as natural nanofactory. We demonstrated for the first time that proteins played a crucial role in determining the size and shape of the metal nanoparticles and the biomolecules layer around the nanoparticles govern the structure function relationship.
Antibiofouling material and antibacterial coating: Bacterial colonization and subsequent biofilm formation is a major cause of death, disability, and socioeconomic loss for millions of people worldwide. Biofilm formation on medical devices is also a major concern in the healthcare industry. Owing to unique physicochemical properties, nanoparticles can strongly regulate their ability to interact and penetrate bacterial cells. Very recently, we have developed antimicrobial peptide coated nanocomposite material as novel anti-biofouling material to combat with bacterial biofilm formation. We also explored antimicrobial mechanism and demonstrated that reactive oxygen species (ROS) generation is the major reason for bactericidal activity. Physical damage of the cell membrane and oxidative decomposition of nucleic acids and proteins also contributed to some extent. The coating of nanobiocomposite material on various surfaces prevented bacterial adhesion and subsequent growth on the surfaces.
Advanced healthcare material: Deaths due to road accidents, terror attacks, and battle field casualties are a real menace of the contemporary times. Recent study revealed that uncontrolled haemorrhage is accounting ~10% of death per year, however, death can be prevented if the haemorrhage is controlled within few minutes of injury. To develop a quick blood clotting agent, we are exploring the potential application of nanomaterial and have formulated a novel hemostatic wound dressing scaffold, which stops the bleeding within minutes and speeding the wound healing process. This hemostatic wound dressing product has been demonstrated and validated in laboratory level for technology evaluation.
Smart hydrogel to stop bleeding and promote wound healing: Topical haemostats have been used to treat visible and accessible injuries. However, non-accessible vascular and internal injuries are life threatening and require immediate attention. The hydrogels has been found to be as promising candidate to serve as haemostat to prevent large volume of blood loss from vascular and internal injuries. Inspired by mother nature, we are exploring the preparation of mussel-inspired injectable hydrogel with haemostatic, tissue adhesive and wound healing properties.
Photodynamic therapy for wound infection: The complications related to bacterial infection at wound sites significantly reduces the wound healing time. Excessive use of antibiotics increased the emergence of drug resistant bacteria and therefore, the treatment of biofilm associated chronic wound infections remain a major challenge. Recent advancement in nanotechnology holds a promising approach for the treatment of biofilm associated wound infection through photothermal therapy. The photothermal ablation using near-IR (NIR) light converts absorbed light into local heat, which kills the bacterial cells with minimal damage to surrounding tissue. We are exploring the development of 3D hybrid hydrogel for non-invasive photothermal ablation of bacterial pathogen and infected wound care management.
