Nanogels (NGs) are presently the focus of extensive research because of their special qualities, including minimal particle size, excellent encapsulating efficacy, and minimizing the breakdown of active compounds. As a result, NGs are great candidates for drug delivery systems. Cross-linked nanoparticles (NPs) called stimulus-responsive NGs are comprised of synthetic, natural, or a combination of natural and synthetic polymers.

Laser surface alloying of Fe, Si, and C on aluminium is demonstrated using a Q-switched Nd:YAG laser as the source of energy. The fundamental wavelength of the laser beam was 1064 nm with an output energy of 100 mJ and a pulse duration of 10 ns. The exposure was conducted in repetitive mode with a frequency rate of 1 Hz.

Bone remodeling, a continuous process of resorption and formation, is essential for maintaining skeletal integrity and mineral balance. However, in cases of critical bone defects where the natural bone remodeling capacity is insufficient, medical intervention is necessary. Traditional bone grafts have limitations such as donor site morbidity and availability, driving the search for bioengineered scaffold alternatives.

Department of Biomedical Engineering, University of Virginia, Box 800759, Charlottesville, Virginia 22908, United States.
Cell entry by enveloped viruses involves a set of multistep, multivalent interactions between viral and host proteins as well as manipulation of nanoscale membrane mechanics by these interacting partners. A mechanistic understanding of these events has been challenging due to the complex nature of the interactions and the event-to-event heterogeneity involved. Single-virus microscopy has emerged as a powerful technique to probe viral binding and fusion kinetics.

Interfacial enzyme catalysis is widespread in both nature and industry. Granular starch is a sustainable and abundant raw material for which a rigorous correlation of the surface structure with enzymatic degradation is lacking. Here pullulanase-catalyzed debranching of 12 granular starches varying in amylopectin contents and branch chain contents and lengths is shown to present a biphasic relationship characteristic of the Sabatier principle.
