Microfluidic health monitoring devices provide revolutionary tools for biological diagnostics and industrial applications. Miniaturized microfluidic sensors integrate key steps such as sample collection, separation, and detection into a single chip and realize automatic and multi-functional analysis. The microfluidic chip is easy to operate, easy to carry, and convenient for on-site deployment, providing a new option for tedious and time-consuming laboratory testing. Microfluidic technology can be further combined with electrochemical, optical, mass spectrometry, and other technologies to greatly expand its function and usability. Microfluidic systems have a wide range of applications in public health monitoring, including food safety management, environmental monitoring, veterinary diagnostics, organic wastewater treatment, and forensic science.

Exosomes have specialized functions and play a key role in different physiological processes and pathological conditions. Consequently, exosomes have attracted increasing attention in their clinical applications for prognosis, diagnosis, drug delivery, and vaccine development. Here, we give an introduction to the different exosome applications.

Immunoglobulin A (IgA) is the most abundantly produced antibody isotype in mammals. The primary function of IgA is to maintain homeostasis on mucosal surfaces and play a role in immune protection. IgA functions mainly through interaction with multiple receptors, including the asialoglycoprotein receptor (ASGPR). ASGPR is a type C carbohydrate-binding lectin that mediates the clearance of various defective plasma glycoprotein molecules from the body. These receptors also identify and bind to pathogen membrane glycoproteins to efficiently clear them from circulation by receptor-mediated endocytosis and play a pivotal role in preventing hepatocyte infections, inflammation, and cancer.

At the end of cytokinesis, the dividing cells are connected by an intercellular bridge, containing the midbody along with a single, densely ubiquitylated circular structure called the midbody ring (MR). MRs are large (about 1.5 m), ring-like macromolecular assemblies that contain several proteins, including centriolin2, MKLP1 (ref. 7), the de-ubiquitylation enzyme USP8 (also known as UBPY)8, and the multifunctional anti-apoptotic ubiquitin ligase BRUCE3, 9, which has a relative molecular mass of 528,000 (Mr 528K).

In vitro diagnostics (IVD) are tests used to detect and diagnose disease, infections, or other medical conditions, including the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. They’re intended for use in the collection, preparation, and examination of specimens taken from the human body.

Half-life extension chemical modification of peptides and proteins has become an essential route to enhance the PK profile of biopharmaceuticals. Herein we provide an overview of some important chemical modifications to extend the half-life of biopharmaceuticals, which are alternatives to PEGylation. The emphasis is on chemical moieties, the biophysical properties they direct, and their biological compatibility. One approach to improving the pharmacokinetic properties of peptides relies on chemical moieties that convey protraction by binding to albumin and promote self-assembly to form larger structures. Biopharmaceuticals modified to bind to albumin have an extended mode of action, which in principle can approach the 19-day half-life of albumin. Alternative strategies to improve PK properties rely on covalent conjugation or fusion with long-lived macromolecules with low immunogenicity.

Research into bacterial ribosomes and the development of ribosome-targeting antibiotics have been important in the fight against pathogenic bacteria and have made outstanding contributions to human health. However, serious problems have developed, including bacterial drug resistance, and the toxicity of ribosomal antibiotics due to their low selectivity. Great advances have been made to deal with the issues of drug resistance and the selectivity and toxicity of ribosomes targeting antibacterial agents). Among all solutions, virtual screening and enzymatic activity assay-based screening to discover ribosome-targeting antimicrobials with novel chemical structures or scaffolds are the most important strategies. However, the complexity of ribosome structures has impeded the development of receptor-based docking, molecular dynamics simulation, and activity-based screening. Recently, advances in ligand-based drug discovery and artificial intelligence have facilitated the virtual discovery of drug development targets in ribosome--ribosomes targeting antimicrobials. In addition, with the development of cryo-electron microscopy technology and novel screening strategies, such as cell-free in vitro transcription and translation systems, opportunities to develop novel antimicrobials with greater accuracy and efficiency are emerging.
