Your brain on mesh: Injectable flexible probe melds with neurons, causes little or no chronic immune response
(Phys.org)—Neuroprostheses, neural probes and other intraneural tissue implants have offered remarkable benefits to recipients in a number of areas in neuroscience research and biomedical applications, therapeutic examples ...
Neuromorphic computing mimics important brain feature
(Phys.org)—When you hear a sound, only some of the neurons in the auditory cortex of your brain are activated. This is because every auditory neuron is tuned to a certain range of sound, so that each neuron is more sensitive ...
Carbon nanotube film restores light sensitivity to blind retinas
(Phys.org) —Light striking the retina in the back of the eye is the first major step in the vision process. But when the photoreceptors in the retina degenerate, as occurs in macular degeneration, the retina no longer responds ...
Of mice and molecules: In vivo photoacoustic imaging using semiconducting polymer nanoparticles
(Phys.org) —Photoacoustic imaging is a hybrid biomedical imaging modality, based on the photoacoustic effect, in which non-ionizing laser pulses are delivered into biological tissues. (More specifically, in the photoacoustic ...
Express yourself: Scientists use genetic algorithm to design self-assembling ssDNA-grafted particles
(Phys.org) —Material design usually follows what is known as the Edisonian method, a traditional process characterized by trial-and-error discovery rather than a systematic theoretical approach. While this may be somewhat ...
Noxious nanotech: Water-borne nanomaterials promote multidrug-resistance gene transfer
(PhysOrg.com) -- The arms race between effective antibiotic prophylaxis and closely related strains or species of bacteria is continually escalating. Bacteria can quickly develop genetic resistance to a range of antibiotic ...
Modeling the miniscule: High-resolution design of nanoscale biomolecules
(PhysOrg.com) -- A key element of both biotechnology and nanotechnology is – perhaps unsurprisingly – computational modeling. Frequently, in silico nanostructure design and simulation precedes actual experimentation. ...
DNA as invisible ink can reversibly hide patterns
(PhysOrg.com) -- While most people know of DNA as the building blocks of life, these large molecules also have potential applications in areas such as biosensing, nanoparticle assembly, and building supramolecular structures. ...
Biomolecular computer can autonomously sense multiple signs of disease
(PhysOrg.com) -- In the future, nano-sized computers implanted in the human body could autonomously scan for disease indicators, diagnose diseases, and control the release of the appropriate drugs. Although this scenario ...
