Near Infrared (NIR) absorbing dyes as promising photosensitizer for photo dynamic therapy

…, G Sivaraman, RN Priyanka, SO Raja… - Coordination Chemistry …, 2020 - Elsevier
Photo Dynamic Therapy (PDT) is regarded as an effective therapeutic approach for cancer,
which employs light and photosensitizing chemical substances. The successful …

A molecular rotor FLIM probe reveals dynamic coupling between mitochondrial inner membrane fluidity and cellular respiration

G Singh, G George, SO Raja… - Proceedings of the …, 2023 - National Acad Sciences
The inner mitochondrial membrane (IMM), housing components of the electron transport
chain (ETC), is the site for respiration. The ETC relies on mobile carriers; therefore, it has long …

Facile synthesis of highly sensitive, red‐emitting, fluorogenic dye for microviscosity and mitochondrial imaging in embryonic stem cells

SO Raja, G Sivaraman, A Mukherjee… - …, 2017 - Wiley Online Library
Bright, sensitive fluorescent probes that respond to changes in the cellular microenvironment
are extremely valuable for imaging cellular dynamics. We report a simple, one‐step …

A tunable palette of molecular rotors allows multicolor, ratiometric fluorescence imaging and direct mapping of mitochondrial heterogeneity

SO Raja, G Sivaraman, S Biswas, G Singh… - ACS Applied Bio …, 2021 - ACS Publications
Environment-sensitive molecular probes offer the potential for a comprehensive mapping of
the complex cellular milieu. We present here a radically new strategy of multiplexing highly …

KMT 1 family methyltransferases regulate heterochromatin–nuclear periphery tethering via histone and non‐histone protein methylation

…, P Kumar, A Mohanty, SD Kumar, SO Raja… - EMBO …, 2019 - embopress.org
Euchromatic histone methyltransferases ( EHMT s), members of the KMT 1 family, methylate
histone and non‐histone proteins. Here, we uncover a novel role for EHMT s in regulating …

Mapping activity-dependent quasi-stationary states of mitochondrial membranes with graphene-induced energy transfer imaging

SO Raja, AI Chizhik, CF Schmidt, J Enderlein… - Nano Letters, 2021 - ACS Publications
Graphene-induced energy transfer (GIET) was recently introduced for sub-nanometric axial
localization of fluorescent molecules. GIET relies on near-field energy transfer from an …
