Scientists report a new strategy to combine microwave thermal therapy with infection inhibition to effectively treat cancer

nanomedicineScientists propose a novel tumor treatment strategy for simultaneous ablating tumor and inhibiting infection by using specially designed biodegradable metal-organic frameworks (MOFs). The strategy of simultaneous eradicating tumor tissue and inhibiting infection can inspire the researchers with novel progressing technologies for tumor therapy. This novel strategy opens the door for developing the nanomaterials that are sensitive to microwave irradiation and inhibiting infection to achieve noninvasive combined treatment in clinical practice.

Nanotechnology machines' interaction with living systems

nanomachineResearch on micro- and nanomachines has advanced from the observation and understanding of basic motion behavior to the constantly improving capabilities of performing complex tasks. This ranges from interaction with bacteria to propulsion based on cells and in vivo medical applications. A review looks at the applications of micro- and nanomachines in living biosystems from two aspects: the interaction of micro/nanomachines with other microscopic organisms or biological units, and the efforts toward application of micro/nanomachines in human body.

Defining the immunological effects of nucleic acid nanoparticles

nanoparticlesProgrammable nucleic acid nanoparticle (NANP) technology is a relatively new field that has already given rise to a host of self-assembling nucleic acid nanoparticles that are increasingly viewed as promising biological materials for medical applications. Programmable self-assembling NANPs are amenable to chemical modifications, control over functionalization, and consistent batch-to-batch formulation. Researchers present the first detailed and systematic study that involved 25 most representative NANPs, originally designed by different groups, screened for the induction of 29 different cytokines.

Cell membrane coating as a platform nanotechnology for medicine

coated_nanoparticleCell membrane coating is a platform technology that presents a facile top-down method for designing nanocarriers with surfaces that directly replicate the highly complex functionalities necessary for effective biointerfacing. This new class of biomimetic nanoparticles combines the advantages of both natural and artificial nanomaterials. Cell membrane-coated nanoparticles are characterized by a synthetic nanoparticulate core cloaked by a layer of natural cell membrane.

Potential nanotechnology applications in combating opioid drug abuse

pillsDrug abuse and dependence/addiction are complex disorders that are regulated by a wide range of interacting networks of genes and pathways that control a variety of phenotypes. Therefore, both identification of the at-risk population and treatment of the addiction disorders are strongly reliant on the development of new and innovative approaches for understanding the mechanisms underlying drug dependency and addiction. There are potential capacities of nanotechnology for the field of drug dependency and addiction.

Turning hair into a biomedical nanomaterial

hairScientists have discovered that the hierarchical micro- and nanostructures of human hair can be turned into hierarchical micro- and nanoparticles with a simple top-down procedure and be used as a novel type of biomaterial for medical applications. This strategy of preparing biomaterials from abundant human hair might provide a potent tool for producing autogenous materials from patients themselves to overcome the drawbacks of synthetic materials.

Transparent graphene implant for deep brain imaging and optogenetics

brain_implantAlthough advances in optical technologies such as multi-photon microscopy and optogenetics have revolutionized researchers' ability to record and manipulate neuronal activity, integration of optical modalities with electrical recordings is challenging due to generation of light-induced artifacts. In new work, scientists report a transparent graphene microelectrode neural implant that eliminates light-induced artifacts to enable crosstalk-free integration of 2-photon microscopy, optogenetic stimulation, and cortical recordings in the same in vivo experiment.

Metal-organic frameworks can enhance sonodynamic cancer therapy

sonosensitizerSonodynamic therapy (SDT) has attracted wide attention as a novel treatment strategy for deep-seated tumors due to its safety, tissue penetration depth and low cost. However, traditional organic sonosensitizers tend to suffer from low water solubility, fast metabolism and elimination from the blood circulation. Sciebtists now report the excellent potential of metal-organic-framework (MOF)-derived mesoporous carbon nanostructures containing porphyrin-like metal centers in SDT augmentation.
