úzkospektrý

úzkospektrý is a Czech adjective that translates to "narrow-spectrum" in English. It is most commonly used in scientific and technical contexts, particularly in fields such as physics, chemistry, and biology.

In physics, úzkospektrý might describe a light source that emits radiation within a very limited range of wavelengths. For example, a laser is often considered a narrow-spectrum light source. This contrasts with broadband sources, such as incandescent bulbs, which emit a wide range of wavelengths.

In chemistry, the term can refer to a reagent or a reaction that is highly selective, affecting only a specific type of molecule or functional group. A narrow-spectrum catalyst, for instance, would catalyze a particular reaction without promoting undesirable side reactions.

In biology, úzkospektrý is frequently used in the context of antimicrobials, such as antibiotics. A narrow-spectrum antibiotic targets a limited range of microorganisms, often specific types of bacteria. This is in contrast to broad-spectrum antibiotics, which are effective against a wider variety of pathogens. The use of narrow-spectrum agents is often preferred when the specific causative agent of an infection is known, as it can help to reduce the risk of developing antibiotic resistance and minimize disruption to the body's natural microbial flora.
