Phys.org / Organ-on-a-chip: 3-D self-rolled biosensor array to electrically interrogate electrogenic cells
Cell to cell communication plays an important role in coordinating the function of biological systems. Three-dimensional (3-D) spheroids (cell aggregates) allow biologists to explore cellular communication during tissue development ...
Medical Xpress / Noninvasive monitoring of chronic kidney disease (CKD) using pH and perfusion imaging
Chronic kidney disease (CKD) is a feature of inherited metabolic disorders such as methylmalonic acidimia (MMA), which can cause impaired growth and low metabolic activity to delay the diagnosis and management of renal disease. ...
Medical Xpress / Engineering collagen-binding serum albumin (CBD-SA) as a drug conjugate carrier for cancer therapy
Medical researchers often use serum albumin (SA) as a drug carrier to deliver cytotoxic agents to tumors during biomedical drug delivery via passive targeting approaches. To improve the targeting capacity of SA's a team of ...
Phys.org / Ultrahigh thermal isolation across heterogeneously layered two-dimensional materials
Heterogeneous nanomaterials can now facilitate advanced electronics and photonics applications, but such progress is challenging for thermal applications due to the comparatively shorter wavelengths of heat carriers (known ...
Phys.org / Self-assembled membrane with water-continuous transport pathways for precise nanofiltration
Self-assembled materials are attractive for next-generation materials, but their potential to assemble at the nanoscale and form nanostructures (cylinders, lamellae etc.) remains challenging. In a recent report, Xundu Feng ...
Phys.org / Holography and criticality in matchgate tensor networks
Tensor networks take a central role in quantum physics as they can provide an efficient approximation to specific classes of quantum states. The associated graphical language can also easily describe and pictorially reason ...
Phys.org / Chemical and physical origins of friction on surfaces with atomic steps
Friction results from a set of complex processes that act together to resist relative motion. Despite this complexity, friction is often described using simple phenomenological expressions that relate normal and lateral forces ...
Phys.org / Metal-oxide semiconductor nanomembrane-based multifunctional electronics for wearable-human interfaces
Wearable electronic human-machine interfaces (HMIs) are an emerging class of devices to facilitate human and machine interactions. Advances in electronics, materials and mechanical designs have offered pathways toward commercial ...
Medical Xpress / Application of hydroxyapatite nanoparticles (n-HA) in tumor-associated bone segmental defect
Materials scientists widely incorporate hydroxyapatite (HA) for bone repair in bone tissue engineering (BTE) due to its superior biocompatibility as a natural component of human bones and teeth. In a recent report on Science ...
Phys.org / Hydrophobic nanostructured wood membrane for thermally efficient distillation
During water desalination, membrane distillation (MD) is challenged by the inefficiency of water thermal separation from dissolved solutes, due to its dependence on membrane porosity and thermal conductivity. For instance, ...
Phys.org / A hybrid material that switches reversibly between two stable solid states
Solid matter typically contains a single, stable solid state for a specific set of conditions. Materials scientists envision that new materials with interchangeable solid states will be advantageous for diverse technical ...
Phys.org / Two-dimensional (2-D) nuclear magnetic resonance (NMR) spectroscopy with a microfluidic diamond quantum sensor
Quantum sensors based on nitrogen-vacancy (NV) centers in diamond are a promising detection mode for nuclear magnetic resonance spectroscopy due to their micron-scale detection volume and noninductive-based sample detection ...
Phys.org / Atomically precise bottom-up synthesis of π-extended [5] triangulene
Chemists have predicted zigzag-edged triangular graphene molecules (ZTGMs) to host ferromagnetically coupled edge states, with net spin scaling with the molecular size. Such molecules can afford large spin tunability, which ...
Phys.org / Bone tissue engineering—nano-glue polymer membranes for robust bone regeneration
In a new study now published on NPG Asia Materials, bioengineers report the development of a new fibrous membrane with stem cells to repair bone defects in the skulls of mice. For this, they incorporated mussel-inspired polydopamine ...
Phys.org / Microfluidics: 2-D fingerprints of heterogenous proteins in solution
Microfluidic systems are used in molecular biology, biochemistry and biotechnology to rapidly analyze heterogenous biomolecular mixtures with high recovery rates and minute sample volumes. However, it is challenging to combine ...
