Nanodiamonds as Bioactive Platforms to Modulate Microbial, Mammalian, and Vertebrate Systems
Advanced NanoBiomed Research, EarlyView.Nanodiamonds (NDs) are biocompatible and antibacterial nanomaterials that support mammalian cell growth while inhibiting bacterial pathogens. NDs showed strong antibacterial activity, with Escherichia coli being more sensitive than Staphylococcus aureus. At 10 mg/mL, both bacteria exhibited ~8% viability.

Advanced NanoBiomed Research, EarlyView.Bowl‐shaped Janus nanomotors with platinum, iron oxide, and polypyrrole integrate catalytic, magnetic, and electric propulsion for targeted drug delivery. They demonstrate controlled, directional motion under varying pH and hydrogen peroxide conditions, with optimal performance in neutral media.

An Evaluation of the Resazurin Test Paper Method for Determining the Sanitary Quality of Raw Milk [PDF]
, 1968 A new reduction method for determining the sanitary quality of raw milk, which in called the resazurin test paper method; was evaluated comparing with the conventioal resazurin test tube method.

THE REDUCTION OF RESAZURIN IN MILK AND AQUEOUS SOLUTIONS
, 1941 The action of resazurin in milk is complex and not as yet clearly understood. The various resazurin tests have been proposed as practical tests for estimating bacterial populations in milk before they have emerged from the experimental stage.

THE BEHAVIOUR OF RESAZURIN IN MILK
, 1942 The view that resazurin is not a satisfactory substitute for methylene blue in assessing the hygienic quality of milk has been examined.Resazurin is equally as sensitive as methylene blue to the metabolic activities of bacteria in milk.

Rapid serial diluting biomicrofluidic provides EC50 in minutes
Micro and Nano Engineering, 2019 Complex water effluents pose a toxicity risk to biological wastewater treatments and environmental discharge. Dynamic sampling and risk assessment of effluents would mitigate downstream hazards, but few methods are available to assess microorganism ...

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors
Biotechnology and Bioengineering, EarlyView.ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Chemistry – A European Journal, EarlyView.The SARS‐CoV‐2 papain‐like protease (PLpro) is a medicinal chemistry target. Here we report mass spectrometry assays employing oligopeptide substrates based on the sequences of the viral polyproteins 1a/1ab and on an ISG15‐modified human protein, which enabled the identification of substrate‐selective PLpro inhibitors.
