Carbon-based stimuli-responsive nanomaterials are gaining much attention due to their versatility, including disease diagnosis and treatment. They work under endogenous (pH, temperature, enzyme, and redox) or exogenous (temperature, light, magnetic field, ultrasound) stimuli. Carbon-based stimuli-responsive nanomaterials can be used as smart materials with dynamically tunable physicochemical properties in response to changes in internal or external environmental stimuli. Their diverse combinations of nanostructures and molecular designs, as well as functional complexes with different carriers, create new opportunities for the development of advanced smart nanomaterials. https://phys.org/news/2023-06-carbon-based-stimuli-responsive-nanomaterials-classification-application.html Bio & Medicine Mon, 05 Jun 2023 11:34:03 EDT news605183641 Inspired by living systems, researchers at Aalto University have developed a new material that changes its electrical behavior based on previous experience, effectively giving it a basic form of adaptive memory. Such adaptive materials could play a vital role in the next generation of medical and environmental sensors, as well as in soft robots or active surfaces. https://phys.org/news/2022-11-generation-material-history.html Materials Science Tue, 15 Nov 2022 10:37:58 EST news587731075 The number of potential therapeutic targets on the surfaces of human proteins is much greater than previously thought, according to the findings of a new study in the journal Nature. https://phys.org/news/2022-04-abundant-secret-doors-human-proteins.html Molecular & Computational biology Wed, 06 Apr 2022 11:04:00 EDT news568461834 Intelligent materials, the latest revolution in the field of materials science, can adapt their properties depending on changes in their surroundings. They can be used in everything from self-healing mobile phone screens, to shape-shifting airplane wings, and targeted drug delivery. Delivering drugs to a specific target inside the body using intelligent materials is particularly important for diseases like cancer, as the smart material only releases the drug payload when it detects the presence of a cancer cell, leaving the healthy cells unharmed. https://phys.org/news/2021-05-scientists-intelligent-material.html Materials Science Wed, 12 May 2021 11:08:35 EDT news540036510 Bioengineers can design smart drugs for antibody and nanomaterial-based therapies to optimize drug efficiency for increasingly efficient, early-stage preclinical trials. The ideal drug will have maximum efficiency at target tissue sites for transport from the tissue vasculature to the cellular environment. Researchers can use biological simulations coupled to in vitro approaches to predict their exposure rapidly and efficiently to predict drug biodistribution within single cells of live animal tissue without relying on animal studies. In a new study now published on Science Advances, Edward Price and Andre J. Gesquiere successfully used an in vitro assay and computational fluid dynamic (CFD) model to translate in vitro cell kinetics to whole-body simulations across multiple species and nanomaterial types. The work allowed them to predict drug distributions inside individual tissue cells and the team expect this work to refine, reduce and replace animal testing while providing scientists a fresh perspective on drug development. https://phys.org/news/2020-02-animal-simulations-smart-drug-nanomaterial.html Bio & Medicine Wed, 12 Feb 2020 09:30:01 EST news500713525 A KAIST research team has developed a flexible drug delivery device with controlled release for personalized medicine, a step toward theragnosis. https://phys.org/news/2018-08-flexible-drug-delivery-microdevice-advance.html Bio & Medicine Tue, 14 Aug 2018 08:33:37 EDT news453454407 A method to activate targeted drugs, or smart drugs, only at the selected site of action, an approach that improves the drug's therapeutic effect and minimizes side effects, has been developed in a study led by Georgia State University. https://phys.org/news/2018-05-chemistry-smart-drugs-smarter.html Materials Science Thu, 17 May 2018 07:55:29 EDT news445762518 Nanotechnology is creating new opportunities for fighting disease – from delivering drugs in smart packaging to nanobots powered by the world's tiniest engines. https://phys.org/news/2017-06-drugs-nanotherapeutics-nanobots.html Bio & Medicine Mon, 26 Jun 2017 05:45:59 EDT news417674743 Arguments in favour of embracing gene editing focus on how it can deliver cheap treatments and cures for some truly awful medical conditions.
