Efficiency and Transparency Enhancement in Environment-Friendly Lead-Free Cs3Sb2I9 Semi-Transparent Perovskite Solar Cells through Quantum Dot Passivation Bhavna Sharma, Namrata Pant, Prathul Nath, Saurabh K. Saini, Rajiv Kumar Singh, Soumitra Satapathi Solar Rrl, 2025 Antimony halide perovskites (AHPs) are promising materials for the development of environmentally friendly semi‐transparent perovskite solar cells (ST‐PSCs). However, the poor device performance due to sub‐optimal film quality and structure‐induced defects in lead‐free AHPs remains a challenge for their potential commercialization. Here, we have addressed this issue by incorporating Cs 3 Sb 2 Br 9 quantum dots (QDs) in lead‐free Cs 3 Sb 2 I 9 ‐based ST‐PSCs and demonstrated that Cs 3 Sb 2 Br 9 QDs passivation in these ST‐PSCs can lead to a three‐fold enhancement in power conversion efficiency (PCE) and −3% increase in average visible transmittance. The higher performance is attributed to the better film formation by controlling crystallization and reducing nonradiative recombination by suppressing the defect states. Our study provides an effective defect passivation approach to develop stable and environmentally friendly ST‐PSCs.

In this study we report the fabrication of a 3D printing assisted microfluidic based absorbance measurement system, leveraging 3D printing along with integrating miniature optical components for the accurate measurement of biological assays. The developed system is rapid, affordable, and compact, through set of computer-aided design models and fusion deposition modeling 3D printing along with relevant electronic circuitry involving optical components like surface mounting devices. The handheld device features a capacitive touchscreen display, programmed to seamlessly perform MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The device was employed for assessing the cell viability using Michigan cancer foundation-7 (MCF-7) cell lines over varying concentrations of tamoxifen, reciprocating the MTT assay analysis conducted by using spectrophotometer. The device achieved excellent results which upon comparison with the conventional spectrophotometer-based results have shown a correlation coefficient of 0.98. This compact and rapid absorbance measurement system holds significant potential for evaluating the cytotoxicity of drugs, and further development of innovative analytical devices.
Highly sensitive and selective detection of dopamine with boron and sulfur co-doped graphene quantum dots Manisha Chatterjee, Prathul Nath, Sachin Kadian, Anshu Kumar, Vishal Kumar, Partha Roy, Gaurav Manik, Soumitra Satapathi Scientific Reports, 2022 In this work, we report, the synthesis of Boron and Sulfur co-doped graphene quantum dots (BS-GQDs) and its applicability as a label-free fluorescence sensing probe for the highly sensitive and selective detection of dopamine (DA). Upon addition of DA, the fluorescence intensity of BS-GQDs were effectively quenched over a wide concentration range of DA (0–340 μM) with an ultra-low detection limit of 3.6 μM. The quenching mechanism involved photoinduced electron transfer process from BS-GQDs to dopamine-quinone, produced by the oxidization of DA under alkaline conditions. The proposed sensing mechanism was probed using a detailed study of UV–Vis absorbance, steady state and time resolved fluorescence spectroscopy. The high selectivity of the fluorescent sensor towards DA is established. Our study opens up the possibility of designing a low-cost biosensor which will be suitable for detecting DA in real samples.
3,6-Diaminocarbazole doped fluorescent electrospun nanofibers for highly sensitive detection of nitroaromatics Anshu Kumar, Vishal Kumar, Prathul Nath, Soumitra Satapathi Journal of Applied Polymer Science, 2022 Electrospinning is an efficient technique to fabricate nanofibers of controlled diameter and uniform morphology. Herein, we report a low‐cost and high‐yield route to fabricate PAN/DAC composite nanofibers and its use for vapor sensing of 2,4‐Dinitrotoluene (DNT) and 2,4,6‐Trinitrotoluene (TNT) with a detection level in the range of parts‐per‐billion. Furthermore, the sensing ability and photo‐induced electron transfer mechanism of DAC towards DNT and TNT in the solution phase were also investigated in detail via absorption, steady‐state, and time‐resolved fluorescence spectroscopy and further supported by density function theory (DFT). The calculated Stern‐Volmer quenching constants, 810 M−1 (DNT) and 1170 M−1 (TNT), revealed that DAC is not much sensitive in solution‐phase because of the self‐condensation phenomenon of DAC molecules. This concern was addressed by the development of a fluorescent nanofiber probe constituting π‐electron‐rich carbazole (CZ) derivatives, namely 3,6‐Diaminocarbazole (DAC) as a fluorescent material and polyacrylonitrile (PAN) as a support polymatrix. This fluorophore‐doped nanofiber matrix was fabricated at a relatively lower wt% ratio (PAN:DAC::10:6), obtaining an average diameter of 857 nm and exhibited promising features in the vapor detection of DNT and TNT such as fast response time, excellent sensitivity and selectivity. Reduction of self‐condensation caused DAC molecules' fluorescence self‐quenching by simply employing the electrospinning technique to cast PAN/DAC nanofibrous film. This work promises a new aspect of sensitivity enhancement of carbazole molecular unit by amine modification and further incorporation into the polymer matrix. This nanofiber‐based sensor can lead to the design and development of highly efficient and field‐deployable vapor sensors for the detection of nitroaromatic compounds, with application in both explosive sensing and environment pollution.
Fabrication of Cysteamine capped-CdSe QDs anchored graphene xerogel nanosensor for facile onsite visual detection of TNT Vishal Kumar, Anshu Kumar, Prathul Nath, Soumitra Satapathi Nano Structures and Nano Objects, 2021 Owing to the importance of explosive detection for the security of land and the environment, the exploration of new methodologies for sensing electron-deficient nitroaromatics explosives (NAEs) is urgently imperative. In this work, we firstly reported a colorimetric sensor for visual detection of 2,4,6-trinitrotoluene (TNT) based on Cysteamine capped-CdSe quantum dots (QDs) decorated graphene-chitosan xerogel (GSXS), which is shown to have high signal-to-background ratio. Meisenheimer complex formation, which is a well-known sensing mechanism, is characterized by steady state and time resolved spectroscopy supported by Density-Functional-Theory (DFT). Upon Green Fluorescent Protein (GFP) illumination, this stable Meisenheimer complex actively suppresses the attributed fluorescence of QD-GSXS and thus providing a novel path for chemical sensing applications. Under optimized conditions, the sensor displayed a wide linear range from 0.0 to 311.4 μ M with a limit of detection 9.7 μ M. The developed chemosensor showed several advantages, including good selectivity and excellent stability. The proposed approach can be utilized for the rapid and sensitive detection of NAEs in the solution phase and also for clinical application.
Repurposing therapeutics for COVID-19: Rapid prediction of commercially available drugs through machine learning and docking Sovesh Mohapatra, Prathul Nath, Manisha Chatterjee, Neeladrisingha Das, Deepjyoti Kalita, Partha Roy, Soumitra Satapathi Plos One, 2020 Background The outbreak of the novel coronavirus disease COVID-19, caused by the SARS-CoV-2 virus has spread rapidly around the globe during the past 3 months. As the virus infected cases and mortality rate of this disease is increasing exponentially, scientists and researchers all over the world are relentlessly working to understand this new virus along with possible treatment regimens by discovering active therapeutic agents and vaccines. So, there is an urgent requirement of new and effective medications that can treat the disease caused by SARS-CoV-2. Methods and findings We perform the study of drugs that are already available in the market and being used for other diseases to accelerate clinical recovery, in other words repurposing of existing drugs. The vast complexity in drug design and protocols regarding clinical trials often prohibit developing various new drug combinations for this epidemic disease in a limited time. Recently, remarkable improvements in computational power coupled with advancements in Machine Learning (ML) technology have been utilized to revolutionize the drug development process. Consequently, a detailed study using ML for the repurposing of therapeutic agents is urgently required. Here, we report the ML model based on the Naive Bayes algorithm, which has an accuracy of around 73% to predict the drugs that could be used for the treatment of COVID-19. Our study predicts around ten FDA approved commercial drugs that can be used for repurposing. Among all, we found that 3 of the drugs fulfils the criterions well among which the antiretroviral drug Amprenavir (DrugBank ID–DB00701) would probably be the most effective drug based on the selected criterions. Conclusions Our study can help clinical scientists in being more selective in identifying and testing the therapeutic agents for COVID-19 treatment. The ML based approach for drug discovery as reported here can be a futuristic smart drug designing strategy for community applications.
