Amorphous Phase Mediated Crystallization: Fundamentals of Biomineralization

open access: yesCrystals, 2018
Many biomineralization systems start from transient amorphous precursor phases, but the exact crystallization pathways and mechanisms remain largely unknown.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

open access: yesFEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

Towards chitosan-amorphous calcium phosphate nanocomposite: Co-precipitation induced by spray drying

open access: yesNext Materials
This article reports the successful one-step synthesis of two micron-sized composite powders consisting of chitosan and amorphous calcium phosphate. These composite materials are prepared by spray drying of a solution containing chitosan and calcium ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Spectrophotometric Evaluation of the Color Change of Artificial White Spot Lesions Treated with Three Different Commercially Available Remineralizing Agents: An In Vitro Study

open access: yesDental Hypotheses, 2022
Introduction: This study evaluated the color changes induced by the treatment of intact and demineralized enamel surfaces with casein phosphopeptide-amorphous calcium fluoride phosphate (CPP-ACFP), casein phosphopeptide-amorphous calcium phosphate (CPP ...

Inhibition of Acid Phosphatase Enzyme Activity in the Presence of Noncrystalline Calcium Phosphate and Nanocrystalline Calcium Apatite: a Preliminary Study [PDF]

open access: yes, 2009
*Background* Our bones are remodelled repeatedly during life. A new and “healthy” bone tissue replaces the old one. Accordingly, the bone degrading cells, the osteoclasts, prefer old and fatigued bone.

Dynamic Observation of Lacy Pattern Formation in a Bone Tissue Model Using Liquid Phase Scanning Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Here, we establish a low‐dose liquid‐phase electron microscopy workflow for real‐time observation of biological processes in hydrated conditions. Beam damage is reduced by imaging only 20% of the pixels and reconstructing the complete image using an inpainting algorithm.

Guided Tissue Remineralization of Resin-Bonded Acid-Etched Dentin [PDF]

open access: yes, 2008
Contemporary biomineralization strategies incorporate non-classical crystallization pathways of fluidic amorphous nanoprecursors and mesoscopic transformation.
