Holistic Analysis of Material Properties in Phylogenetically Diverse Spider Silks and Their Influence on Cell Adhesion

Advanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
Translation of recombinant spider silks as fillers for nerve guidance conduits in long‐segment nerve reconstruction demands a detailed examination of native counterparts. Thus, this study conducts a comprehensive analysis of the material properties of four phylogenetically diverse spider silks and their impact on Schwann cell adhesion, pinpointing key ...

Ultra-Sensitive Hydrogen Peroxide Sensor Based on Peroxiredoxin and Fluorescence Resonance Energy Transfer

Applied Sciences, 2020
In this paper, a fluorescence resonance energy transfer (FRET)-based sensor for ultra-sensitive detection of H2O2 was developed by utilizing the unique enzymatic properties of peroxiredoxin (Prx) to H2O2. Cyan and yellow fluorescent protein (CFP and YFP)

Investigating resonance energy transfer from protein molecules to van der Waals nanosheets [PDF]

arXiv, 2016
The resonance energy transfer (RET) from tryptophan present in bovine serum albumin (BSA) to two dimensional (2D) nanomaterials has been reported. In these bio-nano systems, BSA molecules act as efficient donors while 2D van der Waals nanosheets of graphene, molybdenum disulfide (Mo$S_2$) and tungsten disulfide (W$S_2$) act as acceptors.

Plasmonic engineering of metal nanoparticles for enhanced fluorescence and Raman scattering [PDF]

, 2008
We have investigated the effects of tuning the localized surface plasmon resonances (LSPRs) of silver nanoparticles on the fluorescence intensity, lifetime, and Raman signal from nearby fluorophores. The presence of a metallic structure can alter the optical properties of a molecule by increasing the excitation field, and by modifying radiative and non-

Genetically Controlled Iron Oxide Biomineralization in Encapsulin Nanocompartments for Magnetic Manipulation of a Mammalian Cell Line

Advanced Functional Materials, Volume 35, Issue 13, March 25, 2025.
Genetically expressed encapsulin nanocompartments from Q. thermotolerans in mammalian cells enable the compartmentalization of Fe biomineralization and formation of ≈30 nm iron‐oxide cores containing quasi‐crystallites of up to ≈3 nm size consistent with a maghemite‐like phase.

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

Advanced Functional Materials, EarlyView.
Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Non‐Enzymatic Destruction of the Extracellular Matrix for Activatable Orthotopic Tumor Treatment and Enhanced Drug Penetration

Advanced Functional Materials, EarlyView.
Supramolecular biomimetic nanoaggregates (HFCu NAs), constructed with fluorinated histidine and copper ions via metal coordination and aromatic packing, exhibit enhanced reactive oxygen species （ROS）generation at tumor sites, which results in stepwise collapse of the extracellular matrix (ECM), affording tumor microenvironment responsive “turn‐on” 19F ...

An Engineered Recombinant Spider Silk Protein Providing Disulfide‐Locked Control over Self‐Assembly and Fiber Formation

Advanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
Using atomic structure and local stability information, recombinant aciniform spider silk proteins are rationally engineered to incorporate a chemically switchable disulfide bond to prevent fiber formation. When disulfide‐locked, these proteins cannot form continuous fibers, whereas the unlocked (reduced) state can.
