Development of nanoparticles derived from corn as mass producible bionanoparticles with anticancer activity

Materials Fetal bovine serum (FBS) was obtained from Biosera (East Sussex, UK); nonessential amino acid solution (NEAA), CPZ, sodium phosphotungstate, and 4% PFA were obtained from Nacalai Tesque, Inc. (Kyoto, Japan). PC, cholesterol, and PE were kindly provided by Nippon Fine Chemical Co., Ltd. (Tokyo, Japan). Chloroform, methanol, penicillin–streptomycin-L-glutamine solution (× 100) (PSG), and PI were obtained… Continue reading Development of nanoparticles derived from corn as mass producible bionanoparticles with anticancer activity

Researchers develop new approach to nanoparticles that stop internal bleeding

Credit: CC0 Public Domain When a person experiences a trauma that leads to significant bleeding, the first few minutes are critical. It’s important that they receive intravenous medication quickly to control the bleeding, but delivering the medication at the right rate can prove challenging. Slower infusions can cause fewer negative reactions, but the medication might… Continue reading Researchers develop new approach to nanoparticles that stop internal bleeding

Nanotechnology offers pain relief for tooth sensitivity

Credit: University of Queensland In an Australian first, researchers from the University of Queensland have used nanotechnology to develop effective ways to manage tooth sensitivity. Dr. Chun Xu from UQ’s School of Dentistry said the approach might provide more effective long-term pain relief for people with sensitive teeth, compared to current options. “Dentin tubules are… Continue reading Nanotechnology offers pain relief for tooth sensitivity

Reversible and spatiotemporal control of colloidal structure formation

We engineered a series of dNTP-driven enzymatic reaction networks based on the PEN toolbox32,33, a DNA programming framework designed to construct out-of-equilibrium systems performing DNA amplification (polymerase and nickase, Fig. S1) and DNA degradation (exonuclease, Fig. S2)34,35,36. Enzymatic reactions are used to produce DNA linker strands, which are able to induce the specific structure formation of DNA-coated… Continue reading Reversible and spatiotemporal control of colloidal structure formation

Quantum computational speed of a nanowires system with Rashba interaction in the presence of a magnetic field

In this section, we use the orthogonality to explore the quantum computational speed when the nanowire system is constructed in three distinct starting states as: the pure state, the maximum entangled state, and the superposition state. Let us consider that, the proposed system is prepared initially in the state (|Psi (0)rangle) which evolved for a… Continue reading Quantum computational speed of a nanowires system with Rashba interaction in the presence of a magnetic field

Observing light-induced Floquet band gaps in the longitudinal conductivity of graphene

Model Hamiltonian We consider a circularly polarized laser with frequency ωd = 2π × 48 THz ≈ 200 meV and variable field strength Ed, which illuminates a graphene layer from perpendicular direction. The electromagnetic forces drive the electrons into a steady state. We propose to measure the longitudinal AC conductivity of this steady state in the optical frequency domain. The conductivity displays frequency… Continue reading Observing light-induced Floquet band gaps in the longitudinal conductivity of graphene

Lightwave-driven scanning tunnelling spectroscopy of atomically precise graphene nanoribbons

Lightwave-driven microscopy at ultralow tip heights The graphene nanoribbons are grown from molecular precursors23 on a clean Au(111) substrate by on-surface synthesis22 (see Methods). We select 7-atom-wide GNRs with armchair edges (7-AGNRs) for the current study, as depicted in Fig. 1a. For conventional STM imaging, the tip height z = z0 is defined by the bias voltage Vd.c.… Continue reading Lightwave-driven scanning tunnelling spectroscopy of atomically precise graphene nanoribbons
