Fructose‐Based Single‐Chain Polymer Nanoparticles for GLUT1–Mediated Delivery: Impact of Polymer Design on Uptake and In Vivo Performance

Advanced Healthcare Materials, EarlyView.
Single‐chain nanoparticles have been proposed as drug delivery carriers, but adding a tail can significantly enhance their performance. This was demonstrated using a tadpole‐like structure comprising a head prepared from a UV‐crosslinked fructose‐based glycopolymer capable of targeting GLUT receptors, combined with a PEG‐based tail. Compared with other

Salt resistance of tomato species grown in sand culture

Plant, Soil and Environment, 2010
In this study, Na+, Cl-, K+, Ca2+, chlorophyll and proline levels and the rate of lipid peroxidation level in terms of malondialdehyde (MDA), were investigated in tissues of 15 different tomato cultivars in salt tolerance.

Matrix Stiffness Directs Stemness Signatures in Breast Cancer

Advanced Healthcare Materials, EarlyView.
We built lab‐grown breast cancer models to study how the stiffness of the tumor's surroundings influences cancer behavior. Softer environments encouraged more stem‐like, drug‐resistant cells, while stiffer ones kept cells more differentiated. These findings show that tissue mechanics drive cancer diversity and drug resistance, offering new insights for

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Turning Unpredictable Biomolecule Adsorption to Controlled Corona Formation: Focus on Carbon Nanomaterials

Advanced Materials, EarlyView.
Controlling the protein corona formation onto carbon nanomaterials (CNMs) enhances their functionalities as platforms for cancer theranostics. Here, we reviewed the effects of the intrinsic and acquired properties of CNMs on protein corona formation, the consequent biological and toxicological outcomes, and the strategies to reshape corona formation ...
