Research Interests


Ph.D thesis: Mesoporous silica nanomaterials and silica-coated nanomaterials-application in optical imaging and treatment of cancer related angiogenesis.

Overview:


Angiogenesis stands as a major hallmark in all types of cancer. Cancer, to grow uncontrollably needs essential nutrients and oxygen in high levels and they turn on synthesis of all known angiogenic factors leading to angiogenesis. Thus formed blood vessels feed the cancerous mass and also help in process of metastasis of cancer to a distant region. Targeting the angiogenesis with silica nanoformulations stands as efficient treatment therapeutics to treat cancer. Cutting their blood supply would make cancerous mass to starve for oxygen, nutrients etc., and would also prevent them from infiltrating to distant regions, thereby preventing secondary tumors.

Outline of research:


  • Synthesis of highly porous silica nanoparticle and silica coated nanomaterials for theragnostic application of angiogenesis.
  • Testing them for their efficacy in imaging and therapeutics in in vitro cell cultures using HUVEC and breast cancer cell lines.
  • Medaka embryos vascular disruption study – Pharmacological inhibition of Angiogenesis in vivo using the anti-angiogenicnanoformulation.

Work accomplished:


  • Mesoporous silica nanoparticles are synthesized via modified template directed stober process using tetraethoxysilane as silica source. The mesopores are then efficiently loaded with drug/dye of interest and this nanoformulation is utilized for synergistic targeting of cancer and its related angiogenesis. In vitro and in vivo works are carried out and the efficacy of the nanoformulation against angiogenesis is elucidated.
  • Microemulsion methodology was utilized to prepare silica encapsulated single CdS quantum dots of highly uniform size (20nm). The core CdS are highly luminescent and this core-shell particle appeared to be highly biocompatible and is utilized for endothelial imaging by active targeted mechanism.
  • Drug loaded core-shell magnetic nanoparticle with silica coating are prepared using microemulsion method and these nanoparticles are intended to be used for magnetic separation and hyperthermic therapeutic treatment of cancer.

Research presently involved with:


  • Multiple ligand based targeting of silica based nanoformulations for cancer neo-angiogenesis theragnostics
  • Near infrared based deep tissue imaging using nanocrystals/Quantum dots
  • Nanotoxicology– Toxicity analysis of cadmium based QDs, an in vitro study
  • Interaction of nanoparticles with blood proteins– Protein corona and their effects on biodistribution and pharmacokinetics in vivo Nanohornsbased cancer theragnostics
