Silver nanoparticles inhibit the activity of the enzyme providing oxygen exchange in protozoa, such as pathogenic bacteria, viruses, and fungi (about 700 species of pathogenic flora and fauna) [1]. The transition from the ionic Ag⁺ form to metallic nanoclusters makes it possible to reduce silver’s toxicity to cells of higher organisms without suppression of the antimicrobial activity against pathogenic microflora.

Dr. Anju Ahlawat (Ph.D - Physics), is DST Faculty at Laser and Functional Materials Division, Raja Ramanna center for advanced technology (RRCAT), Indore (India). She has got her B.Sc and M.Sc in Physics. She had awarded her Doctor's degree (Ph.D.) in Physics from UGC -DAE Consortium for scientific research, Indore (India) in 2012. She has received a prestigious research award from DST inspire Faculty in 2014. She has 7 years research experience from RRCAT, Indore, India. Currently Dr. Ahlawat’s research focus is on multiferroic magneto electric nanostructures for memory applications. She has published 30 papers in reputed journals

The modern generation of data storage technology brings new challenges to existing materials for low power data processing, reliable, fast and sizable transfer of data. In this context, artificial multiferroic composites based on ferromagnetic (FM) and ferroelectric (FE) phases that exhibit strong magnetoelectric coupling, hold promise for designing new generation memory devices with several advantages. Multiferroic composites offer innovative approaches for non-volatile memory devices as compared to their semiconductor transistor-based competitors

Zhigang Zou received his Ph.D. degree in 1996 from the University of Tokyo. He is the Cheung Kong Scholars professor in the department of physics, and the director of Ecomaterials and Renewable Energy Research Center (ERERC) in Nanjing University, China. His research interests include superconductor, photocatalysis, and photoelectrochemisty for solar fuel production. He has published over 600 papers, cited for more than 20000 times with the H-index of 72, and achieved more than 90 China's invention patents, 1 U. S. patent, 2 Japanese patents. In 2015, he was elected the member of Chinese Academy of Sciences, and in 2018, he was elected the member of the World Academy of Sciences.

The photocatalytic and photoelectrochemical reduction of water or CO₂ is an intriguing approach to producing sustainable solar fuels, and has attracted growing and intense interest. Nanostructuring of photocatalysts and photoelectrodes has been proven to be a strong strategy to dramatically improve overall solar-to-fuel conversion efficiencies

He received a certificate awarded to him and his experimental group in recognition of significant contribution of 2 patterns to the Powder Diffraction File – Release 2000. The ICDD (International Centre for Diffraction Data) also appreciates cooperation of his group and interest in Powder Diffraction File.

X-ray diffraction profiles and electron diffraction patterns reveal that both alloys exhibit super lattice reflections inherited from parent phase due to the displacive character of martensitic transformation. X-ray diffractograms taken in a long time interval show that diffraction angles and intensities of diffraction peaks change with the aging time at room temperature. In particular, some of the successive peak pairs providing a special relation between Miller indices come close each other, and this result leads to the rearrangement of atoms in diffusive manner

 

Two-dimensional (2D) layered double hydroxide (LDH) nanoparticles have been widely studied for biomedical applications due to its tremendously biocompatible properties at the nanoscale.  Exfoliating LDH nanoparticles into ultrathin nanosheets is an efficient way to maximize the utility of each single layer, which possess the higher specific surface area. However, current exfoliation methods of LDH nanoparticles are either time-consuming or lack of biocompatibility (bottom-up method), which remains a bottleneck for biomedical applications of LDH nanosheets

Prof. Blassan George is currently working as an Associate Professor at the Laser Research Centre, Faculty of Health Sciences, University of Johannesburg. He received NRF Y1 rating in 2021. His research focuses on the development of novel cancer therapies from plants and cancer photodynamic therapy. He has presented research outcomes in more than twenty international conferences. He received research grants from South African Medical Research Council- SAMRC, NRF-DST South Africa-India joint project scheme, NRF Grant for Y Rated researchers, NRF Incentive Funding for Rated Researchers, African Laser Centre (ALC) international research grant with Egypt, NRF-KIC travel grants, and University Research Council (URC) funding from the University of Johannesburg. 

Cancer is a medical disease in which certain body cells proliferate in uncontrolled manner with potential of invading distant body parts. Breast cancer is the type of cancer that originates from the breast tissue and globally it is regarded as the leading cause of cancer related deaths in women. In order to effectively eradicate cancer, therapies such as photodynamic therapy (PDT) are administered in combination with other therapies. A dose-dependence anticancer effects (i.e., morphological changes, cell viability, and cell death mechanisms) of Dicoma anomala methanol extract (D. anomala) (IC₅₀) and zinc phthalocyanine tetrasulfonic acid (ZnPcS₄) mediated-PDT (IC₅₀) on MCF-7 breast cancer cells were evaluated in this study. Morphological changes were observed in D. anomala and ZnPcS₄ mediated PDT treated cells when compared to the control cells. Trypan blue cell viability assay displayed a significant decrease in cell population in D. anomala and ZnPcS₄ mediated PDT treated cells. The Annexin V/propidium iodide assay displayed the apoptotic and necrotic activities in both D. anomala and ZnPcS₄ mediated PDT treated cells as well as in combination therapy. In summary, this study highlighted the anticancer effects of D. anomala as a single chemotherapeutic drug and in combination with ZnPcS₄ photosensitizer on MCF-7 breast cancer cells. In conclusion, this study clearly suggests the use of D. anomala as an adjuvant or inducer to be used alone or applied along with other cancer therapies to enhance the treatment outcome.
