Zinc oxide nanoparticles cause marked up-regulation of pyrimidine biosynthesis and sugar metabolism but consistent down-regulation amino acid synthesis in MRSA, suggesting a previously unrecognized mechanism action.
Chiral plasmonic surfaces with 3D “forests” from nanohelicoids should provide strong optical rotation due to alignment of helical axis propagation vector photons. However, such three-dimensional nanostructures also demand multi-step nanofabrication, which is incompatible many substrates. Large-scale photonic patterns on polymeric and flexible substrates remain unattainable. Here, we demonstrate the substrate-tolerant direct-write printing patterning silver out-of-plane orientation using...

Recent advances in computational tools, particularly the ones involving modern deep learning algorithms, have been shown to complement experimental approaches describing rationalizing PPIs. However, most existing works...
Tissue engineering based on building blocks is an emerging method to fabricate 3D tissue constructs. This requires depositing and assembling (cell-laden microgels) at high throughput. The current technologies (e.g., molding photolithography) microgels have throughput challenges provide limited control over block properties cell density). cell-encapsulating droplet generation technique has potential address these challenges. In this study, we monitored individual for viability, proliferation...
Abstract Chirality is an essential geometric property unifying small molecules, biological macromolecules, inorganic nanomaterials, microparticles, and many other chemical structures. Numerous chirality measures have attempted to quantify this of mirror asymmetry correlate these with physical properties. However, their utility has been widely limited because correlations largely notional. Furthermore, also require prohibitively demanding computations, especially for chiral structures...
