What is Nanotechnology?
Nanotechnology is the science and engineering of manipulating matter at the atomic, molecular, and supramolecular scale. It involves the design, production, and application of materials and devices whose size and shape can be controlled at the nanometer level.
What Are Nanosensors?
Nanosensors are devices that can detect physical, chemical, and biological changes at the nanoscale. They are integral to biomedical diagnostics as they can identify disease-related biomarkers like proteins, nucleic acids, and small molecules with high precision and sensitivity.
What Are Quantum Dots?
Quantum dots are semiconductor nanoparticles that exhibit unique optical properties. In diagnostics, they are used as fluorescent probes for imaging and tracking biological processes in real-time. Their high brightness and stability make them superior to traditional dyes.
How Are Gold Nanoparticles Used in Diagnostics?
Gold nanoparticles have unique optical and electronic properties that make them ideal for use in diagnostic applications. They are often employed in colorimetric assays, where the binding of target molecules to the nanoparticles causes a visible color change, facilitating easy and rapid detection of pathogens or disease markers.
What Is a Lab-on-a-Chip?
A
Lab-on-a-Chip is a miniaturized device that integrates multiple laboratory functions on a single chip. It utilizes microfluidics and nanotechnology to perform complex biochemical analyses. These chips are capable of rapid and accurate diagnostics and are especially useful in point-of-care settings.
What Are Nanopore Sequencers?
Nanopore sequencers are a type of DNA sequencing technology that uses nanopores to detect changes in electrical current as nucleic acids pass through them. This allows for real-time, single-molecule sequencing, providing detailed genetic information that can be crucial for diagnosing genetic disorders and personalizing treatment plans.
