Biocompatibility evaluation of breathing gas pathways in medical devices is a powerful tool for the evaluation of contaminants from the air emitted from the device for Volatile Organic Compounds (VOCs) and particulate matter when the gas pathway is intended to contact a patients’ respiratory tract. Standard for Biocompatibility Evaluation of Breathing Gas Pathways in Medical Device “Chemical Characterization of medical device materials”, part eighteen of the…

Antibody-drug conjugates (ADCs) are conjugated products of monoclonal antibodies (mAbs) and cytotoxic small molecules. In tumor treatment, although monoclonal antibodies have good targeting properties, most of them target extracellular or cell surface antigens, have weak anti-tumor activity, have limited therapeutic effect on solid tumors, and are more likely to develop drug resistance; conventional anti-tumor chemotherapy Although drugs have high anti-tumor cell activity, they lack targeting…

What are Dyed Polystyrene Latex Particles? Polystyrene particles (PSP) are commercially available in different sizes, ranging from 15 nanometers to several micrometers, with narrow size distributions and various surface chemistries. Additionally, polystyrene is generally considered inert and nontoxic, making it safe for use in a variety of biological assays. Dyed polystyrene latex particles or colored latex beads have excellent multiplexing capability and have the following characteristics: a. Diversity,…

Staphylococcus aureus (S. aureus) is an important class of food-borne pathogens that cause food contamination and food poisoning, and is also a symbiont of human skin and mucous membranes. Studies have found that about 20%~30 % of healthy individuals carry Staphylococcus aureus. Animal foods are susceptible to Staphylococcus aureus infection, such as milk, butter, cured ham, etc. Food poisoning incidents caused by Staphylococcus aureus have been frequently reported, and more than…

The incidence and prevalence of diabetes are increasing year by year globally, and patients with diabetes are at increased risk of cardiovascular disease and heart failure. Diabetic cardiomyopathy (DCM) refers to the presence of abnormal myocardial structure and performance in the absence of other heart-related risk factors (such as coronary artery-related disease, hypertension, and severe valvular disease). DCM can lead to cardiac systolic or diastolic…

The biocompatibility systemic toxicity tests are in vivo systemic tests used to evaluate the impairment or activation of a system, rather than the impairment of individual cells or organs. Acute systemic toxicity tests and pyrogenicity tests are included in the systemic toxicity tests. Acute Systemic Toxicity Testing Acute toxicity is considered to be the adverse effects that occur after administration of a single dose or repeated doses…

As a promising systemic drug delivery method, transdermal drug delivery system (TDDS) is easier and more convenient to operate than traditional oral, intravenous and subcutaneous injection methods. It can improve patient compliance while also avoiding First-pass effect and drug side effects. As the largest organ of the human body, the skin is also the body’s first line of defense against foreign microorganisms and chemical substances. Its drug…

What is Zeta Potential? Zeta potential (ZP) is a physical property exhibited by any particle in a suspension, macromolecule or material surface. ZP is an analytical technique used to determine the surface charge of nanoparticles in colloidal solutions. The surface of a charged particle attracts and binds firmly to a thin layer of opposite charge, forming a thin layer of liquid called the Stern layer;…

Alzheimer’s disease (AD) is a progressive neurodegenerative disease with an insidious onset. Clinically, it is characterized by comprehensive dementia manifestations such as memory impairment, aphasia, apraxia, agnosia, impairment of visuospatial skills, executive dysfunction, and personality and behavioral changes. Alzheimer’s disease is progressive and irreversible and can only be delayed with medication. Once it develops into moderate or severe disease, it will cause significant harm to…

Herpes simplex virus (HSV) belongs to the herpesvirus alpha subfamily and has a unique 4-layer structure. The core of HSV is a linear double-stranded DNA of about 152 000 bp, surrounded by an icosahedral capsid. The outer capsid is a membrane, which contains more than 20 important proteins that can regulate the virus replication cycle. It is a characteristic structure of herpes viruses, can connect…
