Unfortunately, I cannot create a summary of the requested article because the available search results only contain a basic description from the ChemRxiv[1] database, which does not contain enough content to create a detailed factual summary. The available text only states that the work "establishes innovative organoboron chemistry as a strategy to enable the chemical synthesis of proteins at low concentrations"[1], but does not include the specific data, methodology, statistics, or main findings needed to meet your requirements. To create an accurate 6-8 sentence summary in Slovak with verified facts, statistics and main findings, I would need access to the full text of the article from the journal Science, Volume 391, Number 6785 (February 2026).
