Inserting mechanical drugs into living cells (w/video)

mechanical-drugThe mechanical properties of cells and their intracellular mechanical loads are as relevant for a cell's accurate functioning as the biochemical portion of the cell. This offers a novel perspective that addresses the study of cell mechanics and even the alteration of the mechanical equilibrium of the cells by using silicon chips as an intracellular intervention mechanism. These 'echanical drugs' open the possibility to determine and measure intracellular forces and internalization routes. They can also produce intracellular mechanical perturbations by altering the cell cycle and even, if they are designed accordingly, destroy the cells.

Nanotechnology-enabled low-cost, point-of-care, self-test of sodium in the comfort of your home

nanoparticlesResearchers have developed a point-of-care, portable, rapid, and cost-effective test for clinical diagnosis of sodium, which uses a paper printed colorimetric sensor that is based on Curcumin-functionalized copper (CuC) nanoparticles. They demonstrate that the proposed CuC paper strip can be used for detecting Na+ concentration within the whole physiological range in both blood serum and urine. Sodium is a vitally important electrolyte present in all body fluids and it plays a crucial role in maintaining normal body function, including nerve and muscle function.

Nanotechnology versus viruses

nanocarrierA recent review article highlights how nanoscience and nanotechnology can solve three acute problems in the treatment, prevention, and diagnosis of viruses like SARS-CoV-2: 1) synthesis of novel drugs and vaccines based on nanocarriers with enhanced efficiency and reduced side-effects for the treatment of the current pandemic and the prevention of future virus attacks; 2) design of protective equipment based on nanoparticles, such as medical face masks and outfits and 3) development of nanobiosensors for early detection of infections in a maximally efficient way.

Nanotechnology for face masks

face-masksSince the beginning of the COVID-19 pandemic in 2020, researchers have intensified their efforts to improve the performance of antiviral and antibacterial face masks by adding various functionalities such as metal nanoparticles and herbal extracts to inactivate pathogens, using graphene to make masks photothermal and superhydrophobic, and even using triboelectric nanogenerators to prolong mask lifetime. Based on these works, manufacturers have developed different mask styles and air filtration materials using various nanomaterials.

Chemically programmed nanotranslators facilitate communication between microorganisms from different kingdoms

cellThe design of chemical communication networks at the micro/nanoscale is an emergent interdisciplinary topic with potential applications in diverse areas such as sensing, biomedicine, biotechnology, and information and communication technologies. Previously, researchers have demonstrated communication between synthetic microvesicles and one type of cells. Communicating cells from different kingdoms has not been achieved before. Now, scientists report a proof-of-concept study that appears to be the first realization of a programmed cross-kingdom communication involving two species of living cells enabled by nanoparticles.

Meet ELI - a nanotechnology neuroprosthetic that may one day integrate with neurons

endomycorrhizaScientists have designed a nanobot neuroprosthetic that it has been inspired from nature by way of endomyccorhizae - a type of plant/fungus symbiosis, which is over four hundred million years old. During endomyccorhizae, fungi use numerous threadlike projections called mycelium that penetrate plant roots, forming colossal underground networks with nearby root systems. During this process fungi take up vital nutrients while protecting plant roots from infections - a win-win relationship. Consequently, the nano-neuroprosthetic has been named 'endomyccorhizae ligand interface', or 'ELI' for short.

Optimizing methods for stable storage of nucleic acid nanoparticles and their transportation at ambient temperatures

nucleic-acid-nanoparticleNucleic acid nanoparticles (NANPs) have found success in a variety of biochemical applications ranging from nanoscaffolds for coordinated delivery of multiple therapeutic nucleic acids (TNAs) to potent immunoregulators and biosensors. Despite their potential, the true viability of NANPs and TNAs is limited by their relative chemical instability and sensitivity to higher temperatures. Shipping and transportation of NANPs and TNAs currently relies on a cold-chain storage. Newly developed methods could reduce the need for cold chain storage and dramatically improve vaccine shelf life.

The future of learning: Cambridge Advance Online meets bionanotechnology

Cambridge_Advance_OnlineBeing a relatively young field, Bionanotechnology is often neglected within undergraduate and postgraduate curriculum. With an increasing number of researchers and professionals of different backgrounds coming into the field, there is a clear need to have learning platforms that cover techniques, strategies and methods that characterise the design of bionano structures. In September 2021, Cambridge Advance Online, a new educational initiative created between the University of Cambridge and Cambridge University Press and Assessment, launched a 6-week online course about Bionanotechnology: Bionanotechnology from Theory to Practice.
