A rapid, simple and one step microwave mediated method for synthesizing C-dots using poly(ethylene glycol) (PEG) as a precursor passivating agent is reported. The possessed low cytotoxicity, were amenable to separation by electrophoresis, photostable entered cancer cells, making them suitable candidates bioimaging biolabelling.
We report the finding of presence carbon nanoparticles (CNPs) in different carbohydrate based food caramels, viz. bread, jaggery, sugar caramel, corn flakes and biscuits, where preparation involves heating starting material. The CNPs were amorphous nature; particles spherical having sizes range 4-30 nm, depending upon source extraction. results also indicated that formed at higher temperature smaller than those lower temperature. Excitation tuneable photoluminescence was observed for all...
Two-dimensional molybdenum disulfide (MoS2) based nanosheets functionalized or loaded with an antimicrobial agent have recently attracted attention as highly efficient antibacterial agent. MoS2 sheets act the photothermal transducers in inducing bacterial cell death on impingement of NIR radiation enabled inactivation by wrapping around cells. However, intrinsic ability to effective without use any external stimuli is still not well explored. This study provides a detailed mechanism action...
The current pandemic caused by SARS-CoV-2 has seen a widespread use of personal protective equipment, especially face masks. This created the need to develop better and reusable masks with built-in antimicrobial, self-cleaning, aerosol filtration properties prevent transmission air-borne pathogens such as coronaviruses. Herein, molybdenum disulfide (MoS2) nanosheets are used prepare modified polycotton fabrics having excellent antibacterial activity photothermal properties. Upon sunlight...
Abstract Electronic skin (E‐skin) that can mimic the flexibility and stretchability of human with sensing capabilities, holds transformative potential in robotics, wearable technology, healthcare. However, developing E‐skin poses significant challenges such as creating durable materials skin‐like flexibility, integrating biosensing abilities, using advanced fabrication techniques for or implantable applications. To overcome these hurdles, a 3D‐printed electronic utilizing novel class...
We report the use of biopolymer-stabilized ZnS quantum dots (Q-dots) for cation exchange reaction-based easy sensing and removal heavy metal ions such as Hg(2+), Ag(+), Pb(2+) in water. Chitosan-stabilized Q-dots were synthesized aqueous medium observed to have been converted HgS, Ag(2)S, PbS presence corresponding ions. The transformed showed characteristic color development, with Hg(2+) being exceptionally identifiable due visible bright yellow formation, while brown coloration was other...
The synthesis of plasmonic nanorattles with accessible electromagnetic hotspots that facilitate highly sensitive detection chemical analytes using surface enhanced Raman scattering (SERS) is demonstrated. spectra obtained from individual demonstrate the significantly higher SERS activity compared to solid nanostructures.
Rapid emergence of multidrug-resistant bacterial strains has posed a global threat to public health. Hospital-acquired infections, especially in diabetic and burn patients, severely impede the process wound healing, thereby causing high mortality. This calls for developing new biomaterial that synergistically destroys pathogenic also helps promoting healing without any resistance generation. A highly potent antibacterial agent been developed by integrating bactericidal properties MoS2...
Abstract The fabrication of a versatile nanocarrier based on agglomerated structures gold nanoparticle (Au NP)–lysozyme (Lyz) in aqueous medium is reported. carriers exhibit efficient loading capacities for both hydrophilic (doxorubicin) and hydrophobic (pyrene) molecules. nanocarriers are finally coated with an albumin layer to render them stable also facilitate their uptake by cancer cells. interaction between the payloads non‐covalent. Cell viability assay vitro showed that themselves...
The gold nanocluster (GNC), because of its interesting photoluminescence properties and easy renal clearance from the body, has tremendous biomedical applications. Unfortunately, it never been explored for super-resolution microscopy (SRM). Here, we present a protein-conjugated red emissive GNC radial fluctuation (SRRF) lysosome in HeLa cells. diameter obtained SRRF is ∼59 nm, which very close to original smallest Conjugation protein aided specific labeling lysosome. We hope that not only...
Hybrids of graphene and metal plasmonic nanostructures are promising building blocks for applications in optoelectronics, surface-enhanced scattering, biosensing, quantum information. An understanding the coupling mechanism these hybrid systems is vital importance to its applications. Previous efforts this field mainly focused on spectroscopic studies strong within hybrids with no spatial resolution. Here we report direct imaging local between single Au nanocapsules step edges at nanometer...
Despite recent developments, surface-enhanced Raman spectroscopy (SERS) applications face challenges in achieving both high sensitivity and uniform signals over a large area. Using the directional self-assembly of plasmonic nanoparticles lattice structures, we show how one can increase SERS signal 43-fold randomly aligned gold without relying on photoluminescence Rhodamine 6G. For this study, have chosen constant for an off-resonant case that matches resonance super-radiant plasmon mode...
Acute lymphoblastic leukemia (ALL) is the most common pediatric hematological malignancy, with ETV6::RUNX1 being prevalent translocation whose exact pathogenesis remains unclear. IGF2BP1 (Insulin-like Growth Factor 2 Binding Protein 1) an oncofetal RNA binding protein seen to be specifically overexpressed in positive B-ALL. In this study, we have studied mechanistic role of leukemogenesis and its synergism fusion protein.
