Here we report on the biomimetic synthesis of Pd nanoparticles for use as models green catalytic systems. The nanomaterials are synthesized using peptides isolated via phage-display techniques that specific to surfaces. Using this synthetic strategy, peptide-functionalized 1.9 ± 0.3 nm in diameter produced, which soluble and stable aqueous solutions. Once characterized, these biobased materials were then used catalysts drive formation C−C bonds Stille coupling reaction. Under conditions an...
One of the promises nanoparticle (NP) carriers is reformulation promising therapeutics that have failed clinical development due to pharmacologic challenges. However, current nanomedicine research has been focused on delivery established and novel therapeutics. Here we demonstrate proof principle using NPs revive potential abandoned compounds wortmannin (Wtmn) as a model drug. Wtmn potent inhibitor phosphatidylinositol 3' kinase-related kinases but translation drug-delivery We engineered NP...
Nanoparticles’ drug release kinetics can directly affect their therapeutic efficacy and toxicity.
A lot of pep: Simple changes to the sequence peptide nanostructures were found maintain stability and enhance activity peptide-based palladium nanocatalysts. histidine alanine substitution in chain afforded an increase turnover frequency from 2234 5224, which suggests that modulates functionality bio-inspired nanomaterials. Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available...
The structure, stability, and aggregation potential of short Au nanorods under biological-based solution conditions have been studied. These attributes were studied using UV−vis spectroscopy, transmission electron microscopy, ζ-potential analysis, dynamic light scattering. stability the materials depended strongly upon both purity solvent used to prepare nanorod solutions. When dissolved in Tris buffer at concentrations less than 10.0 mM, no was observed; however, when comprised with between...
The main goal of self-assembly processes is to arrange nanomaterials in specific orientations produce designer three-dimensional architectures. These structures are produced response desired target systems where a arrangement materials required for structural, electronic, or optical applications. level complexity attained using present materials-based relatively low, while highly complex regularly nature through developed after millennia evolution. By modeling biomimetic with current...
Understanding the surface orientation and interactions between biomolecules nanoparticles is important in order to determine their effects on final structure activity. At present, limited analytical techniques are available probe these interactions, especially for materials dispersed solution. We recently demonstrated that arginine, a simple amino acid, able bind of Au segregated pattern, which produces an electronic dipole across structure. As result, formation linear chains occurred was...
e13546 Background: A key research objective in radiation oncology is to identify agents that can improve chemoradiotherapy. Nanoparticle (NP) chemotherapeutics possess several properties, such as preferential accumulation tumors, are uniquely suited for To facilitate the clinical translation of NP chemoradiotherapy, we conducted preclinical evaluation Genexol-PM, only clinically approved chemotherapeutic with a controlled drug release profile, radiosensitizer using non-small cell lung cancer...
Depression is common in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). Patients depression have an earlier onset rapid progression of decline. Medial temporal lobe atrophy (MTA) AD MCI, some degree found almost all patients. In the present study, attempt was made to know if MTA more AD/MCI than those without it.Patients reporting outpatient department a neurology centre tertiary care hospital were recruited for study. After initial general physical neurological...
Radiotherapy is a key component of cancer treatment. Because its importance, there has been high interest in developing agents and strategies to further improve the therapeutic index radiotherapy. DNA double-strand repair inhibitors (DSBRIs) are among most promising However, their clinical translation limited by potential toxicity normal tissue. Recent advances nanomedicine offer an opportunity overcome this limitation. In study, we aim demonstrate proof principle evaluating nanoparticle...
We demonstrate proof of principle that nanoparticle delivery chemosensitizers can improve efficacy chemotherapy without increasing toxicity.
Biomacromolecules represent new structures employed for the fabrication, assembly, and subsequent use of nanomaterials a variety applications. By genetically selecting binding abilities these bio-based molecules, generation materials with enhanced environmentally sound properties is possible. Unfortunately, level understanding as to how biomolecules bind arrange on nanomaterial surface incomplete. Recent experimental theoretical results suggest that dependent upon peptide composition,...
The yeast vacuolar membrane protein Ycf1p and its mammalian counterpart, MRP1, belong to the ABCC subfamily of ATP-binding cassette transporters. Genetic evidence suggests that casein kinase 2α, Cka1p, negatively regulates function via phosphorylation Ser251 within N-terminus. In this study, we provide strong Cka1p Ser251. We show CK2 holoenzyme interacts with Ycf1p. However, genetic analysis only is required for phosphorylation, as deletion CKA1 significantly reduces in vivo. Furthermore,...
Au nanomaterials are well-known for their optical properties, where nanorods have demonstrated unique capabilities because of readily tunable size and shape. Unfortunately, functionalization the material surface is challenging lack stability after only a few purification cycles. Here, we demonstrate that enhanced Au-nanorod can be achieved by purifying materials using dilute cetyltrimethylammonium bromide (CTAB) wash solutions. To this end, in such manner shifts passivant on/off equilibrium...
Recent experimental evidence has suggested that bioinspired techniques represent promising avenues toward the production of functional nanomaterials possess a high degree activity.
