This review explores the application of graphene-based materials (GBMs) in biomedicine, focusing on graphene oxide (GO) and its interactions with peptides and proteins. GO, a versatile nanomaterial with oxygen-containing functional groups, holds significant potential for biomedical applications but faces challenges related to toxicity and environmental impact. Peptides and proteins can be functionalized on GO surfaces through various methods, including non-covalent interactions such as π-π stacking, electrostatic forces, hydrophobic interactions, hydrogen bonding, and van der Waals forces, as well as covalent bonding through reactions involving amide bond formation, esterification, thiol chemistry, and click chemistry. These approaches enhance GO's functionality in several key areas: biosensing for sensitive biomarker detection, theranostic imaging that integrates diagnostics and therapy for real-time treatment monitoring, and targeted cancer therapy where GO can deliver drugs directly to tumor sites while being tracked by imaging techniques like MRI and photoacoustic imaging. Additionally, GO-based scaffolds are advancing tissue engineering and aiding tissues' bone, muscle, and nerve tissue regeneration, while their antimicrobial properties are improving infection-resistant medical devices. Despite its potential, addressing challenges related to stability and scalability is essential to fully harness the benefits of GBMs in healthcare.

Extracellular vesicles (EV), including exosomes or small EV (sEV) derived from biological fluids, such as milk, have garnered increasing interest in veterinary medicine because of their role in the pathophysiology and understanding of the disease status of the host. Bovine milk serves as a rich source of sEV, containing diverse cargoes of nucleic acids, proteins, and lipids, which play a critical role in intercellular communication and regulation of host status. Although it is more difficult to isolate and purify sEV from bovine milk than from human breast milk, challenges persist in enabling the enrichment and analysis of sEV populations, facilitating the elucidation of their functional roles and prognostic potential in cattle diseases.

Tinnitus arises from the intricate interplay of multiple, parallel but overlapping networks, involving neuroplastic changes in both auditory and non-auditory activity. Tailor-made notched music training (TMNMT) has emerged as a promising therapeutic approach for tinnitus. Residual inhibition (RI) represents one of the rare interventions capable of temporarily alleviating tinnitus, offering a valuable tool that can be applied to tinnitus research to explore underlying tinnitus mechanisms.

Bacteriocins, a class of molecules produced by bacteria, exhibit potent antimicrobial properties, including antiviral activities. The urgent need for treatments against SARS-CoV-2 has proposed bacteriocins such as enterocin DD14 (EntDD14) as potential therapeutic agents. However, the mechanism of macromolecular interaction of EntDD14 for the inhibition of SARS-CoV-2 is not yet fully understood, and its efficacy against variants like JN.

Biosurfactants are biodegradable, non-toxic, and environmentally beneficial substances that are produced by microorganisms. Due to their chemical characteristics and stability in various environmental circumstances, biosurfactants are low-molecular-weight, surface-active molecules of great industrial importance. The choice of the producer microbe, kind of substrate, and purification technique determine the chemistry of a biosurfactant and its production cost.

Highly ordered ultrathin nanosheets (NSs) of Au(I)-Cys were fabricated through aggregation-induced supramolecular self-assembly triggered by an extended agitation in an alkaline environment. The synthesized Au(I)-Cys NSs exhibited intense luminescence and exceptional chirality. Remarkably, additions of biothiols to Au(I)-Cys NSs have significantly enhanced their luminescence emission, and circular dichroism properties coupled with morphological modulations into nanoflowers, nanodendrites, or closely packed aggregates.
