Engineering Microbial Particles for Next‐Generation Biomedical Platforms

open access: yesAdvanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

THz time-domain spectroscopy of mixed CO2–CH3OH interstellar ice analogs [PDF]

open access: yes, 2016
The icy mantles of interstellar dust grains are the birthplaces of the primordial prebiotic molecular inventory that may eventually seed nascent solar systems and the planets and planetesimals that form therein.

Fermented Citrus as a Functional Food Matrix: Evaluating Probiotic, Prebiotic, and Postbiotic Potential

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Fermented citrus transforms bioactive compounds into metabolites with probiotic and prebiotic properties, enhancing gut health, immunity, and metabolic balance. This review highlights fermentation's role in developing sustainable, health‐promoting functional foods while addressing challenges in process optimization, sensory quality, and commercial ...

The Problem of the "Prebiotic and Never Born Proteins"

open access: yes, 2012
It has been argued that the limited set of proteins used by life as we know it could not have arisen by the process of Darwinian selection from all possible proteins.

Length and sequence relaxation of copolymers under recombination reactions

open access: yes, 2017
We describe the kinetics and thermodynamics of copolymers undergoing recombination reactions, which are important for prebiotic chemistry. We use two approaches: the first one, based on chemical rate equations and the mass-action law describes the ...

The Algorithmic Origins of Life [PDF]

open access: yes, 2012
Although it has been notoriously difficult to pin down precisely what it is that makes life so distinctive and remarkable, there is general agreement that its informational aspect is one key property, perhaps the key property.

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

open access: yesAngewandte Chemie International Edition, EarlyView.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

A prebiotic basis for ATP as the universal energy currency

open access: yesPLoS Biology, 2022
ATP is universally conserved as the principal energy currency in cells, driving metabolism through phosphorylation and condensation reactions. Such deep conservation suggests that ATP arose at an early stage of biochemical evolution. Yet purine synthesis

Open Prebiotic Environments Drive Emergent Phenomena and Complex Behavior

open access: yesLife, 2019
We have been studying simple prebiotic catalytic replicating networks as prototypes for modeling replication, complexification and Systems Chemistry. While living systems are always open and function far from equilibrium, these prebiotic networks may be ...

Hydrogen peroxide thermochemical oscillator as driver for primordial RNA replication

open access: yes, 2014
This paper presents and tests a previously unrecognised mechanism for driving a replicating molecular system on the prebiotic earth. It is proposed that cell-free RNA replication in the primordial soup may have been driven by self-sustained oscillatory ...
