Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

This handbook provides a resource for those already familiar with some kinds of micro-particles who wish to learn more about others, or for those just starting out in the study of microremains who wish to have a broad understanding about microscopic archaeology.

We develop open micro cavities to trap light in small volumes and thereby increase the interaction with intra-cavity emitters. Important aspects in this development are the optical penetration in the mirrors, coupling between optical modes, and scattering and clipping losses.

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

Leiden physicists have developed a way to address how accurately a superconducting single photon detector (SSPD) can be characterized by detector tomography. SSPDs are not fully understood, and tomography is a key element to determine how these devices detect light. A better understanding of these detectors…

Physicists, including Leiden researcher, Sanli Faes, have devised a new technique for studying processes at microscale rapidly and extremely precisely. This new method will make it easier to develop antiviral medication. And it doesn’t stop there. Publication in ACS Nano.

The CIGR comprises research groups from the Institute of Biology Leiden (IBL), the Leiden Institute of Chemistry (LIC), the Leiden Academic Centre for Drug Research (LACDR) and the Leiden Institue of Physics (LION).

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

Alireza Mashaghi from the Leiden Academic Centre for Drug Research (LACDR) will use state-of-the-art technology to investigate proteins that play a role in muscular dystrophy. His goal is to provide new insights for designing novel therapeutic strategies in the future. To accomplish this, Mashaghi receives…

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

The specialisation consists of 120 European Credit Transfer System (EC) points and includes mandatory courses and electives (60 EC) and two research projects (60 EC).

In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

Quantum computers deserve their own quantum internet. This is a network that dispatches information not in the form of bits - ones and zeros - but rather as qubits, just like in the quantum computer itself. In the view of Dirk Bouwmeester, a professor in Leiden’s Quantum Matter & Optics research group,…
