Due to their special energy level structure, quantum dots exhibit unique physical properties. This article mainly discusses some properties of quantum dots, including quantum confinement effect, quantum size effect, surface effect and luminescence property.
Quantum dots, also known as semiconductor nanocrystals, are nanoscale materials composed of a small number of atoms. The number of atoms in a quantum dot is usually between a few and a few hundred, and their size in all three dimensions are less than 100 nm. The movement of carriers in the three dimensions of quantum dots is limited by the size effect. Due to the quantum confinement effect, the energy levels of carriers in quantum dots are similar to those of atoms having a discontinuous energy level structure, so quantum dots are also c…

The novel DUBTAC therapeutic platform enables the development of novel drugs against a wide range of human diseases, including cancer and neurodegenerative diseases as well as a variety of inherited diseases, by targeting abnormally degraded pathogenic proteins previously thought to be untargeted.
The use of Proteolysis Targeting Chimeras (PROTACs) to degrade dysfunctional proteins has shown great potential to target proteins that were previously considered “undruggable”, and several projects have entered clinical evaluation worldwide.   Aberrant protein degradation, in fact, is also a pathogenic mechanism in some diseases, such as cystic fibrosis (CF) and some forms of cancer. Therefore, for these diseases, targeted protein stabilizers (TPS), rather than targeted protein degraders (TP…

Staining is one of the most important steps in the preparation of biological microscope slides. First destroy the selective permeability of the cell membrane, and then use the dye to immerse the biological tissue in the dye, so that a certain part of the tissue cells is dyed with a different color or depth of color from other parts, resulting in different refractive indices for observation.

Amplexor’s Renato Rjavec describes practical steps to building the skills for a data-driven future.
Most life sciences Regulatory teams still think and work in terms of documents. Yet it is data, rather than pre-prepared dossiers, that is moving into focus and many companies do not have the necessary skills base to handle this. Stakeholders across the life sciences and healthcare ecosystem are increasingly realising that a data-first approach to collecting, managing and communicating product information will be the most efficient and reliable way to maintain consistent, definitive, current and high-quality record of a product entering or on the market. One that can be interpreted and use in a wide range of use cases, by the broadest possible range of people (from regulators to clinicians, p…

CYP450 has been extensively studied since its discovery was reported in 1962 in the journal JBC, including structural features, catalytic mechanisms, regulation, and many other aspects of biochemistry. Scientists believe that further research and engineering advances on CYP450 will bring great benefits to synthetic biology in the future.
Overview of Cytochrome P450 Cytochrome P450 (CYP450), is a family of hemoglobin-coupled monooxygenases. In mammals, CYP450 oxidizes steroids, fatty acids, and xenobiotics, playing an important role in the metabolism of various compounds as well as in the synthesis and breakdown of hormones. In plants, they regulate the synthesis of defense compounds, fatty acids, and hormones. With the progress of research, the effects of CYP450 on organic synthesis and dru…

A data-first approach to content sharing, using flexible and dynamic data objects, is consigning structured document authoring to history. Generis’ James Kelleher explains how a shift towards real-time data as a single source of truth is fast replacing the traditional structured document authoring approach.
Structured authoring was designed to be the future of document authoring – the ultimate efficiency in presenting information. But a data-driven approach to information sharing is set to address issues with version control and provide a more traceable line back to the master source of intelligence. This does mean that structured document authoring, as a much-anticipated technology proposition, is already obsolete - before it really had a chance to get off the ground. The original concept…

Engineered bacteria can be used as anticancer agents, in which suitable bacterial strains are engineered to colonize hypoxic tumor environments and provide therapeutic payloads.
Engineered bacteria can be used as anticancer agents, in which suitable bacterial strains are engineered to colonize hypoxic tumor environments and provide therapeutic payloads. The hypoxic microenvironment changes tumor cell metabolism and leads to cell quiescence, which contributes to tumor cell resistance to therapy. Live bacteria can inherently colonize areas of hypoxic tumors. In tumor-bearing mice, the intravenously injected bacteria were initially delivered nonpreferentially to healthy and tumor tissues. Over time, the nontumor tissues and circulating bacteria were rapidly cleared, whereas the tumor bacteria…
