Journal ArticleDOI
Green synthesized silver nanoparticles destroy multidrug resistant bacteria via reactive oxygen species mediated membrane damage
Balaram Das,Sandeep Kumar Dash,Debasish Mandal,Totan Ghosh,Sourav Chattopadhyay,Satyajit Tripathy,Sabyasachi Das,Sankar Kumar Dey,Debasis Das,Somenath Roy +9 more
TL;DR: A new method appears promising for green biosynthesis of pure Ag NPs with potent antimicrobial activity, and inhibited biofilm formation by both Escherichia coli and S. aureus.
Journal ArticleDOI
A naphthalene-based Al3+ selective fluorescent sensor for living cell imaging
Animesh Sahana,Arnab Banerjee,Sudipta Das,Sisir Lohar,Debasis Karak,Bidisha Sarkar,Subhra Kanti Mukhopadhyay,Asok K. Mukherjee,Debasis Das +8 more
TL;DR: An efficient fluorescent Al(3+) receptor, L, synthesized by the condensation reaction between 2-hydroxy naphthaldehyde and diethylenetriamine, high selectivity and affinity in ethanol (EtOH) as well as in HEPES buffer at pH 7.4, makes it suitable to detect intracellular Al( 3+) with fluorescence microscopy.
Journal ArticleDOI
Rhodamine-based fluorescent probe for Al3+ through time-dependent PET-CHEF-FRET processes and its cell staining application.
Animesh Sahana,Arnab Banerjee,Sisir Lohar,Bidisha Sarkar,Subhra Kanti Mukhopadhyay,Debasis Das +5 more
TL;DR: Rhodamine-diformyl p-cresol conjugate has been developed as a novel Al(3+)-selective fluorometric and colorimetric sensor based on the FRET mechanism for the first time and shows pH-dependent emission properties viz. an intense red emission at acidic pH and an intense green fluorescence at basic pH.
Journal ArticleDOI
Fluorescent probes for selective determination of trace level Al3+: recent developments and future prospects
TL;DR: In this article, the authors present a review of the literature on fluorescence sensing of Al3+ worldwide together with their own contribution in this field, focusing on greenness of the methods, particularly the use of greener solvents like water.
Journal ArticleDOI
A naphthalene exciplex based Al3+ selective on-type fluorescent probe for living cells at the physiological pH range: experimental and computational studies
Arnab Banerjee,Animesh Sahana,Sudipta Das,Sisir Lohar,Subarna Guha,Bidisha Sarkar,Subhra Kanti Mukhopadhyay,Asok K. Mukherjee,Debasis Das +8 more
TL;DR: Experimentally observed structural and spectroscopic features of HL and its Al(3+) complex have been substantiated by computational calculations using density functional theory (DFT) and time dependent densityfunctional theory (TDDFT).
