Journal ArticleDOI
Near Infrared (NIR) absorbing dyes as promising photosensitizer for photo dynamic therapy
P. Chinna Ayya Swamy,Gandhi Sivaraman,Ragam N. Priyanka,Sufi O Raja,Kandhasamy Ponnuvel,Jeyabalan Shanmugpriya,Akash Gulyani +6 more
TL;DR: This review is an attempt to give a comprehensive overview about the recent advancement in NIR absorbing dyes such as BODIPYs, Keio Fluors, Aza-BODIPy, Chorin, Phthalocyanines, Cyanine dyes, and Nano particles based NIR photosensitizers and their potential in PDT.
Journal ArticleDOI
Facile Synthesis of Highly Sensitive, Red‐Emitting, Fluorogenic Dye for Microviscosity and Mitochondrial Imaging in Embryonic Stem Cells
TL;DR: It is shown that hemicaynine (HC-1) is also a sensitive probe for the spatial heterogeneity of mitochondrial organization in embryonic stem cells as well as dynamic remodeling of the mitochondria in early-differentiated cells.
Journal ArticleDOI
Iron oxide nanoparticles coated with gold: Enhanced magnetic moment due to interfacial effects
TL;DR: In this paper, the authors show that when nanoparticles of Fe3O4 are coated with gold there is a distinct enhancement of magnetization by a factor of six, which is attributed to large orbital magnetic moment formation at the magnetic particle/Au (core/shell) interface.
Journal ArticleDOI
Surface tunability of nanoparticles in modulating platelet functions.
Suryyani Deb,Sufi O Raja,Anjan Kr-R. Dasgupta,Rajkumar Sarkar,Asoke P. Chattopadhyay,Utpal Chaudhuri,Pradipta Guha,Partha Sardar +7 more
TL;DR: The main objective of the present work was to study how platelet functions were changed in the presence of different nano-surface or surface capping, which may provide a measure for the safety of a nanoparticle, and also assess the use of such nanoparticles in platelet modulation.
Journal ArticleDOI
Highly lattice-mismatched semiconductor-metal hybrid nanostructures: gold nanoparticle encapsulated luminescent silicon quantum dots.
Mallar Ray,Tuhin Shuvra Basu,Nil Ratan Bandyopadhyay,Robert F. Klie,Siddhartha Ghosh,Sufi O Raja,Anjan Kr. Dasgupta +6 more
TL;DR: Emission kinetics of the hybrid system show accelerated decay due to non-radiative energy transfer between the Si QDs and the Au NPs and associated quenching in PL efficiency and the quantum yield remains high (∼20%) which renders these hetero-nanostructures exciting candidates for multifarious applications.
