Genetic toxicology testing evaluates the potential of the test material to induce the gene mutation or chromosome damage using a range of bacterial, mammalian cells in vitro and in vivo test systems. STEMart offers multiple test types for genotoxicity biocompatibility testing, following the OECD guidelines modified for medical devices and performing under GLP conditions. Genetic Toxicology Testing for Medical Devices Bacterial […]

Melamine (1, 3, 5-triamino-2, 4, 6-triazine) resin, or melamine formaldehyde (MF) is one of the hardest and stiffest thermosetting polymers, which provides good properties and performance. It is an amino resin and has various material advantages, such as transparency, better hardness, thermal stability, excellent boil resistance, scratch resistance, abrasion resistance, flame retardant, moisture resistance and surface

Nano drug delivery system refers to the drug delivery system composed of natural or synthetic polymer materials with a particle size of 1-1000 nm. Nano-drug delivery carriers have the characteristics of biodegradability, low drug toxicity, slow-controlled release and targeted drug delivery, and are widely favored by researchers in the field of medicine. Metabolism, which can

Introduction for anti-PEG antibodies Polyethylene glycol (PEG), a classic non-fouling water-soluble synthetic polymer, is broadly used in the field of pharmaceutics for proteins and drug carriers1. The covalent coupling of PEG to proteins and drug carriers, a process known as PEGylation, is crucial to maintaining the colloidal stability of drugs in biological fluids and reducing their uptake by

Prevalence and Perniciousness of Monkeypox Virus Monkeypox is a rare disease that is caused by infection with monkeypox virus. Monkeypox virus belongs to the Orthopoxvirus genus in the family Poxviridae. The Orthopoxvirus genus also includes variola virus, vaccinia virus and cowpox virus. Monkeypox was first discovered in 1958 when two outbreaks of a pox-like disease

Hemocompatibility testing is designed for medical devices contacting circulating blood. Biomaterials that contact blood could have cellular effects and humoral effects including thrombosis, embolism, activation of the coagulation, etc. For devices contacting with circulating blood, hemocompatibility testing is generally required as a biocompatibility assessment. STEMart offers multiple test types for Hemocompatibility biocompatibility testing including hemolysis, in

Sodium alginate is a sodium salt of polyanionic alginic acid. It is a natural high molecular polysaccharide polymer extracted from natural brown algae. It has the advantages of wide source, low price, good biocompatibility, and degradability. Contains multiple hydroxyl and carboxyl functional groups, so it can react with a variety of divalent or trivalent cations to
