PDB Viewer vs 晶体光学实验室

PDB Viewer turns your phone into a molecular microscope. Search the entire Protein Data Bank and over 200 million AlphaFold predictions, then explore any protein, virus, drug, or DNA structure in interactive 3D — free, with no account, no ads, and no sign-up. WHERE THE MOLECULES COME FROM • RCSB Protein Data Bank — 200,000+ experimentally determined structures • AlphaFold — 200M+ AI-predicted protein models • SWISS-MODEL — template-based homology models • PubChem and ChEMBL — millions of drugs and compounds • Crystallography Open Database — small-molecule crystals • NCI/CADD resolver — type a chemical name and get a 3D model Every source is free and needs no API key. You can also open your own .pdb and .cif files. WAYS TO SEE IT • Five representations: wireframe, ball-and-stick, space-filling (CPK), cartoon/ribbon, and a smooth molecular surface • Color by element, chain, secondary structure, rainbow, or AlphaFold confidence (pLDDT) • Biological assemblies: rebuild an entire icosahedral virus capsid from a few deposited chains • NMR ensembles: overlay every model in the bundle to watch a protein flex • Automatic secondary-structure detection MADE FOR TOUCH • Rotate, pinch-zoom, and pan with smooth native rendering • Tap any atom to see its element, residue, and chain • Recently viewed structures are cached, so they reopen instantly and work offline For students, researchers, teachers, and the simply curious. PDB Viewer makes structural biology beautiful and accessible. Structures are provided by their respective databases. PDB Viewer is independent and not affiliated with or endorsed by the RCSB PDB, EMBL-EBI, or AlphaFold.

晶体光学实验室是一款面向晶体学、矿物学和宝石学学习者的交互式教学工具。无需账号，主要实验与计算在设备本地完成，可离线使用。 【转动晶体，理解形态】 浏览矿物标本，观察晶轴、晶面与面族；调整参数，比较晶体形态变化。晶体单形图鉴收录 47 类单形，提供点群、面指数与构造说明。 【探索光学现象】 通过色散、多色性、偏振与光轴实验，观察取向、波长和厚度等参数如何影响模拟结果。使用偏光仪教学场景，比较正交和平行偏光下的现象。 【体验宝石模拟】 按矿物匹配不同琢型，在正常光与突出火彩两种照明下观察宝石。比较色散与多色性；琢型匹配用于教学展示，并非最优切割建议。 【快速开始实验】 从钻石、石英、坦桑石等实验出发，一键载入教学参数，再自由调节。滑杆配合数值编辑，便于精确设置与比较。 【适配手机与平板】 iPhone 使用可展开的参数面板；iPad 提供侧边导航、标本库和参数检查器。通过拖动、捏合与双击操作三维视图。 【了解模型边界】 应用区分文献数据、推导结果与教学假设，并提供学术来源。模拟颜色受模型与显示设备影响，结果仅供教学与探索，不构成实物鉴定、估价、认证或测量结论。 应用不含广告或第三方分析 SDK。实验参数保留在当前运行会话中，结束进程后不会保存。查看外部学术来源或在线支持需要联网；隐私政策和使用帮助可在应用内离线阅读。 技术支持：18314@qq.com
