NanoStruct

Overview

NanoStruct (NanoStruct GmbH) is a deep-tech startup based in Würzburg, Bavaria, Germany. It develops nanostructured sensor chips that are read out with optical spectroscopy and evaluated with machine learning, with the current commercial focus on detecting harmful bacteria in food samples in hours rather than days. According to the company's own site https://www.nanostruct.eu and the investor profile of High-Tech Gründerfonds, the company was founded in 2021 as a spin-out from Julius-Maximilians-Universität Würzburg.

Why this entity matters

Microbiological testing in the food industry still relies heavily on culture-based laboratory methods that can take several days, which means products may already be in the supply chain before a contamination is detected. NanoStruct's approach, which combines nanostructured surfaces for surface-enhanced Raman spectroscopy (SERS) with AI-based evaluation, targets that delay. In a seed-round announcement in May 2026 the company and its investors described the aim of same-day results that could help prevent recalls and reduce food waste. NanoStruct is also a typical example of the university-spin-out deep-tech pattern that Startuprad.io follows across the DACH region, where research-grade physics and photonics are turned into a product for a specific industrial testing problem.

Company or institutional background

NanoStruct is headquartered in Würzburg. Its team page names Dr. Henriette Maaß as CEO, Enno Schatz as CTO and technology expert, and Kai Leibfried as the financial expert, alongside specialists in machine learning, nanostructuring, microbiology and sensor-chip production. High-Tech Gründerfonds (HTGF) lists the same three people as founders. In July 2021 the company won first place in the Business Plan Competition Northern Bavaria, organized by BayStartUP and LfA Förderbank Bayern; at that time BayStartUP described the company as producing biosensors for SERS analysis, with envisaged applications in drug development and in the detection of pollutants, explosives or viruses. By 2026 the stated commercial focus had narrowed to bacterial analysis in food. On 12 May 2026, Bionity reported a seed round of 2.6 million euros with High-Tech Gründerfonds, Bayern Kapital and the AUXXO Female Catalyst Fund, intended to fund pilot projects in food analysis, the build-up of a sales organization and entry into the food-testing market. The platform is also described as having potential in veterinary and human diagnostics; this is a stated ambition and not an established product line.

Role in the ecosystem

NanoStruct sits in the DACH deep-tech segment of sensing, spectroscopy and food-safety diagnostics, and in the Bavarian university-spin-out ecosystem around Würzburg. It is relevant to food producers, contract laboratories and quality-assurance teams that need faster pathogen screening, and to investors who track the intersection of nanotechnology, biotechnology and applied AI.

Selected relationships and affiliations

Public sources name High-Tech Gründerfonds, Bayern Kapital and the AUXXO Female Catalyst Fund as seed investors (May 2026, per Bionity and HTGF). The company's origin is attributed to Julius-Maximilians-Universität Würzburg. It was a winner of the 2021 Business Plan Competition Northern Bavaria (BayStartUP and LfA Förderbank Bayern).

Startuprad.io relevance

Startuprad.io introduced NanoStruct in June 2021 in a dedicated startup profile titled "They Are Listening to Molecules", and the company is tagged again in a January 2025 deep-dive on emerging technologies in biopharmaceutical production. The 2021 profile describes the company's spectroscopy-with-nanostructures approach for biotech, pharma and food-industry applications.

Public source context

This record draws on NanoStruct's own website https://www.nanostruct.eu , the High-Tech Gründerfonds portfolio page, the BayStartUP competition announcement of July 2021, Bionity's May 2026 funding report and Startuprad.io's own archive coverage listed below. The technology description is taken from company and investor statements and has not been independently verified, and no revenue, customer or headcount figures were found in public sources, so none are given.
