3D-printed plasmonic plastic enables large-scale optical sensor production (30/09/2023)
In a multi-year project,
researchers at Chalmers University of Technology in Sweden have developed
plasmonic plastic—a type of composite material with unique optical properties
that can be 3D-printed. This research has now resulted in 3D-printed optical hydrogen
sensors that could play an important role in the transition to green energy and
industry.
Separating molecules requires a lot of energy. This nanoporous, heat-resistant membrane could change that (30/09/2023)
Industry has long relied upon
energy-intensive processes, such as distillation and crystallization, to
separate molecules that ultimately serve as ingredients in medicine, chemicals
and other products.
Researchers challenge long-standing theory guiding nanoparticle treatment of tumors (30/09/2023)
Researchers at the University of
Toronto have developed a new theory to explain how nanoparticles enter and exit
the tumors they are meant to treat, potentially rewriting an understanding of
cancer nanomedicine that has guided research for nearly four decades.
Stacking order and strain boosts second-harmonic generation with 2D Janus hetero-bilayers (30/09/2023)
A group of researchers from
Tohoku University, Massachusetts Institute of Technology (MIT), Rice
University, Hanoi University of Science and Technology, Zhejiang University,
and Oak Ridge National Laboratory have proposed a new mechanism to enhance
short-wavelength light (100–300 nm) by second harmonic generation (SHG) in a
two-dimensional (2D), thin material composed entirely of commonplace elements.
Researchers develop minimal nanozymes with carbon dioxide capture capacity (30/09/2023)
Autonomous University of
Barcelona (UAB) researchers have developed minimal nanozymes with the capacity
of capturing carbon dioxide (CO2) emitted in industrial processes—and
applicable to other environmental remediation processes—based on artificial
molecular structures formed by the peptides of only seven amino acids.
Magnetic bead manipulation in microfluidic chips for biological application (30/09/2023)
In recent years, microfluidics
has emerged as a revolutionary technology for biological analysis and medical
diagnostics, enabling the precise control and manipulation of fluids at the
microscale. At the same time, functionalized magnetic beads have become an
indispensable tool for the selective capture and enrichment of target analytes.
Technique for 3D printing metals at the nanoscale reveals surprise benefit (29/09/2023)
Late last year, Caltech
researchers revealed that they had developed a new fabrication technique for
printing microsized metal parts containing features about as thick as three or
four sheets of paper.
Wearable aptamer nanobiosensor wirelessly monitors estrogen in sweat (29/09/2023)
The sex hormone commonly known as
estrogen plays an important role in multiple aspects of women's health and
fertility. High levels of estrogen in the body are associated with breast and
ovarian cancers, while low levels of estradiol can result in osteoporosis,
heart disease, and even depression. (Estrogen is a class of hormones that
includes estradiol as the most potent form). Estradiol is also necessary for
the development of secondary sexual characteristics in women and regulates the
reproductive cycle.
New study on the genetic magnetization of living bacteria shows great potential for biomedicine (29/09/2023)
Magnetic bacteria possess
extraordinary capabilities due to the magnetic nanoparticles, the magnetosomes,
which are concatenated inside their cells. A research team at the University of
Bayreuth has now transferred all of the approximately 30 genes responsible for
the production of these particles to non-magnetic bacteria in a broad series of
experiments.
Integrating 2D materials for on-chip photonics (28/09/2023)
Recently, the introduction of nonlinear optical functions in integrated optics has sparked significant enthusiasm. Demonstrations have shown the potential for integrated photonic platforms. Furthermore, large-scale manufacturing capability and affordability have motivated the development of fully integrated, nonlinear optical devices, aiming at various applications, such as all on-chip spectroscopy, on-chip quantum computations and communications, efficient multiplexing for data communications, on-chip metrology, bio-sensing, or LIDARs.
