Journal ArticleDOI
Electrophoretically deposited reduced graphene oxide platform for food toxin detection
Saurabh Srivastava,Saurabh Srivastava,Vinod Kumar,Azahar Ali,Pratima R. Solanki,Anchal Srivastava,Gajjala Sumana,Preeti S. Saxena,Amish G. Joshi,Bansi D. Malhotra +9 more
TL;DR: The electrochemical sensing results of the anti-AFB1/RGO/ITO based immunoelectrode obtained as a function of aflatoxin concentration show high sensitivity and improved detection limit and the association constant for antigen-antibody interaction obtained as 5 × 10(-4) ng mL(-1) indicates high affinity of antibodies toward the antigen ( AFB1).
Journal ArticleDOI
Colorimetric detection of cholesterol based on highly efficient peroxidase mimetic activity of graphene quantum dots
Narsingh R. Nirala,Shiju Abraham,Vinod Kumar,Anushka Bansal,Anchal Srivastava,Preeti S. Saxena +5 more
TL;DR: In this article, an enzyme mimetic of horse radish peroxidase (HRP) was used for detecting free cholesterol in graphite using GQDs, which is a simple and quick one-step wet chemical method.
Journal ArticleDOI
Study of mechanism of enhanced antibacterial activity by green synthesis of silver nanoparticles
Upendra Kumar Parashar,Vinod Kumar,Tanmay Bera,Preeti S. Saxena,Gopal Nath,Sunil K. Srivastava,Rajiv Giri,Anchal Srivastava +7 more
TL;DR: A novel green synthesis of silver nanoparticles using Guava (Psidium guajava) leaf extract is described, which suggests the possible reduction of Ag(+) by the water-soluble ingredients of the guava leaf like tannins, eugenol and flavonoids.
Journal ArticleDOI
Different shades of cholesterol: Gold nanoparticles supported on MoS2 nanoribbons for enhanced colorimetric sensing of free cholesterol
Narsingh R. Nirala,S. Pandey,Anushka Bansal,Vijay Singh,Bratindranath Mukherjee,Preeti S. Saxena,Anchal Srivastava +6 more
TL;DR: A cholesterol detection color wheel which is used along with cost effective cholesterol detection strips fabricated out of proposed MoS2 NRs-Au NPs system for quick and reliable detection of free cholesterol using unaided eye is proposed.
Journal ArticleDOI
Facile, rapid and upscaled synthesis of green luminescent functional graphene quantum dots for bioimaging
Vinod Kumar,Vimal Singh,Sima Umrao,Vyom Parashar,Shiju Abraham,Anand K. Singh,Gopal Nath,Preeti S. Saxena,Anchal Srivastava +8 more
TL;DR: It is found that the synthesized FGQDs do not show a drastic change in emission properties when kept under different pH conditions, which makes them a potential candidate for in vivo imaging, where the pH of the culture media plays a crucial role in the maintenance of the fluorescence.
