However, achieving autonomous cargo capture, guided transport, and on-demand release within a single light-driven platform remains challenging because cargo capture and release are often coupled to the same propulsion mechanism. Here, we report visible-light-driven hematite\u2013titania (\u03b1-Fe2O3\/TiO2) Janus micromotors that decouple cargo capture and cargo release through photocatalytically generated phoretic interactions and magnetic actuation. Under blue-light illumination, the micromotors exhibit autonomous propulsion with speeds up to 8.5 \u03bcm s\u20131 while operating at a low hydrogen peroxide concentration of only 0.5% (v\/v). The micromotors enable repeated cargo pickup, transport, selective collection from mixed particle populations, and on-demand cargo release, while a single micromotor can simultaneously transport more than 15 silica microparticles. Importantly, magnetic-field-induced micromotor reorientation triggers cargo release without interrupting propulsion or altering the chemical environment. Numerical simulations support the proposed phoretic cargo-capture mechanism, while high-speed imaging and repeated release experiments provide complementary evidence for the magnetically triggered cargo-release strategy and its high repeatability. By independently controlling cargo capture and cargo release through complementary photocatalytic and magnetic mechanisms, this work establishes a versatile strategy for programmable microscale cargo manipulation.<\/jats:p>","DOI":"10.1021\/acsami.6c19045","type":"journal-article","created":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T20:02:09Z","timestamp":1792612929000},"source":"Crossref","is-referenced-by-count":0,"title":["Visible-Light-Driven Hematite\u2013Titania Janus Micromotors for Programmable Cargo Manipulation with Magnetically Triggered Release"],"prefix":"10.1021","author":[{"given":"Hemant","family":"Kumar","sequence":"first","affiliation":[{"name":"Indian Institute of Technology Bhilai , , Kutelabhata, Durg , , ,","place":["Bhilai, Chhattisgarh, India, 491002"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suvendu Kumar","family":"Panda","sequence":"additional","affiliation":[{"name":"Tampere University , , ,","place":["Tampere, Finland, 33720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-2256-9512","authenticated-orcid":true,"given":"Kanhu Charan","family":"Andia","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Bhilai , , Kutelabhata, Durg , , ,","place":["Bhilai, Chhattisgarh, India, 491002"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3550-2102","authenticated-orcid":true,"given":"Sayan","family":"Das","sequence":"additional","affiliation":[{"name":"BITS Pilani , , ,","place":["Hyderabad, India, 500078"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8624-9293","authenticated-orcid":true,"given":"Dhruv Pratap","family":"Singh","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Bhilai , , Kutelabhata, Durg , , ,","place":["Bhilai, Chhattisgarh, India, 491002"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,22]]},"reference":[{"issue":"44","key":"2026102116015797800_cit1","doi-asserted-by":"publisher","first-page":"9846","DOI":"10.1002\/adma.201603586","article-title":"Capture of 2D Microparticle Arrays via a UV-Triggered Thiol-yne \u201cClick\u201d Reaction","volume":"28","author":"Walker","year":"2016","journal-title":"Adv.
